00:30On va faire cette conférence sur les oculaires OVNI NAD Vision.
00:33La première chose qui est importante à comprendre, c'est que OVNI, ça signifie Oculaire de Vision Nocturne Intensificateur.
00:40Donc vraiment, Oculaire, Vision Nocturne Intensificateur, d'où le nom OVNI.
00:45Aujourd'hui, on va traiter de ces oculaires qui vont permettre d'amplifier à la fois la lumière visible, donc le spectre visible,
00:52mais également tout ce qui est dans l'ultraviolet et dans l'infrarouge.
00:55On a vraiment ces trois grandes longueurs d'onde qui vont pouvoir être amplifiées par les oculaires.
00:59La société a été fondée en 2019.
01:02Aujourd'hui, on a deux produits principaux et toute une gamme d'accessoires.
01:06On est basé à Royan, en Charente-Maritime, certains doivent connaître.
01:11On a deux oculaires qui vont permettre de toucher à la fois les observateurs visuels,
01:18ceux qui vont faire de l'astrophotographie, voire également les professionnels.
01:22Après, on peut ensuite déboucher sur plein d'autres possibilités qu'on va explorer durant cette présentation.
01:28Le tout premier produit qui a vu le jour, ça a été l'OVNI-M en 2019.
01:36Il y a eu deux ans d'ER&D entre 2017 et 2019 pour aboutir à l'OVNI-M.
01:40Donc vraiment, novembre 2019, ce mois-ci en fait nos cinq ans,
01:44on a eu l'OVNI-M qui a été officialisé en trois versions différentes.
01:48M signifie monoculaire, donc oculaire de vision nocturne intensificateur, c'est la version monoculaire.
01:54Donc trois niveaux de version, quelques accessoires également qui ont été proposés.
01:58Et puis en 2020, cette fois-ci, on a sorti l'OVNI-B.
02:01Donc là le B, cette fois-ci, ça signifie binoculaire.
02:04Donc M monoculaire, B binoculaire.
02:06De la même façon, on a continué à développer différents accessoires,
02:10comme la focale adapteur, c'est quelque chose qu'on verra par la suite.
02:13Et également, on a continué au niveau des performances, à améliorer toujours les performances.
02:19C'est-à-dire que l'OVNI-M, par exemple, qui au départ a été proposé en version 1800, 2100, 2400,
02:25aujourd'hui on le propose dans des versions qui sont 2200, 2400 et 2600.
02:31Donc vraiment des versions qui évoluent toujours.
02:34Les performances, comme dans toute technologie, vont évoluer durant les années.
02:41Et de ce fait, 2025, vous devrez voir un nouveau produit,
02:46alors j'en parlerai un petit peu plus à la fin,
02:48qui sera l'OVNI-S, qui lui sera vraiment plus dans un cadre scientifique.
02:52Et en parallèle également, parmi les accessoires, il y a des filtres, il y a des adapteurs pour caméras.
02:57L'OVNI en fait ne prend pas de photos, ce n'est pas une technologie numérique, c'est analogique.
03:01Donc si vous voulez prendre des photos, il faut ajouter une caméra, un appareil photo et faire vos propres photos.
03:07Ça c'est pour ceux qui vont vouloir faire de l'astrophotographie.
03:10Et puis on a également le smartphone adapteur, qui permet de mettre un petit téléphone à l'arrière pour prendre des photos rapides.
03:16On arrive à faire de très belles choses avec des smartphones aujourd'hui.
03:20Donc voilà, toute une gamme d'accessoires qui continuent de se développer.
03:24Il y en a un que je n'ai pas mis d'ailleurs, mais ce sera décembre 2024 ou janvier 2025, je ne savais pas où le mettre.
03:30C'est un nouvel objectif frontal qui permet un grossissement de trois fois.
03:35Donc vraiment d'ici deux à trois mois, il sera fait.
03:39Il est entre les deux pour le moment au niveau de la présentation.
03:42L'OVNI M que j'ai ici, vous voyez en fait, il est très petit.
03:49Ça ressemble à un oculaire classique en termes de taille.
03:52Il fait 244 grammes, 10 centimètres.
03:55Et vraiment, c'est celui-ci qui va vous permettre à la fois de faire du visuel et de la photo pour ceux qui aiment faire de la photo.
04:02C'est plus optimisé pour ces deux disciplines.
04:05Donc on va avoir différentes choses de celui qui sont intéressantes à comprendre.
04:08C'est que tout d'abord, il est avec un réglage dioptrique à l'arrière qui permet vraiment de s'adapter à la vue de chaque personne.
04:15On a tous des vues plus ou moins bonnes.
04:17Donc il est important de pouvoir s'adapter vraiment à toutes les personnes.
04:22On a ensuite un bouton de contrôle du gain à l'avant.
04:25Ce petit bouton permet de contrôler la luminosité.
04:29C'est-à-dire que quand vous allez observer, même si ce n'est pas du numérique, c'est de l'analogique,
04:33on va quand même pouvoir augmenter ou baisser la luminosité que l'on va avoir.
04:38Ensuite, on a d'autres petites choses qui sont utiles.
04:44Par exemple, le filetage avec le C-Moon à l'avant va permettre de mettre différents types d'objectifs à l'avant.
04:51Ici, là, on est sans objectif.
04:53Là, on est vraiment dans la configuration plug-and-play.
04:56On va mettre son instrument directement dans le porte-oculaire du télescope.
05:00Après, si on veut faire d'autres méthodes, comme la mode à focale qu'on verra par la suite,
05:05on va pouvoir mettre des objectifs à l'avant.
05:07On peut également mettre des objectifs de tout type de caméra ou d'appareil photo
05:12qui sont vraiment très variés, que ce soit du Sony.
05:16Toute marque va pouvoir s'adapter directement à l'avant.
05:19C'est vraiment très utile pour pouvoir grossir et observer dans différents objets.
05:27On a aussi la possibilité, depuis quelques semaines, de pouvoir customiser l'ovni.
05:33C'est quelque chose d'assez simple.
05:35Mettre un peu de couleur, c'est mieux que d'avoir du tout noir.
05:38Par défaut, c'est tout noir.
05:39Mais si on veut avoir un peu de couleur, aujourd'hui c'est possible.
05:42C'est vraiment quelque chose qui est assez rigolo pour pouvoir se distinguer par rapport aux autres.
05:49Ensuite, je vous parlais de l'ovni B, qui est la version binoculaire.
05:53Cette fois-ci, pour les deux yeux.
05:55L'ovni B est vraiment fait pour de l'observation visuelle pure,
05:58même si certains, des fois, mettent des caméras dessus.
06:01Parce qu'on peut mettre, pourquoi pas, deux caméras plutôt qu'une seule.
06:03Mais en soi, l'ovni B, c'est plus pour ceux qui font du visuel.
06:07L'ovni M, plus ceux qui vont vouloir faire de l'astrophoto.
06:11Chez l'ovni B, ici, on a une binoculaire qui est un peu plus grande que l'ovni M,
06:16mais qui reste tout de même très petite et assez légère.
06:20On est sur du 500 grammes.
06:22Comparé à une binoculaire classique, qui est généralement dans les ordres de 1, voire 1,5 kg,
06:26on est quand même beaucoup, beaucoup plus bas.
06:29Ce qui est plutôt agréable pour le porte-oculaire.
06:32De la même façon, on va pouvoir le mettre directement dans le porte-oculaire.
06:35Ici, on a vraiment la configuration au foyer.
06:38On met sa bino directement dans son porte-oculaire,
06:40soit avec le coulant à 25, 31, 75 millimètres,
06:44ou le coulant en 50,8 millimètres.
06:47De la même façon, on a le réglage d'optique à la base de chaque oculaire.
06:53Qui va se trouver ici.
06:55Ici, on peut régler également la vue pour chaque personne.
06:58Ce qui est important aussi, c'est qu'on a tous des yeux avec des écarts plus ou moins importants.
07:02On va avoir le réglage interpupillaire.
07:04On peut rapprocher ou écarter directement les deux oculaires,
07:08ce qui est vraiment utile pour avoir une image qui soit bien nette.
07:13De la même façon, on va avoir cette fois-ci le réglage du gain,
07:16qui va se trouver à l'avant via une petite molette.
07:19On a une petite flèche à contrôle manuel du gain,
07:22qui va se trouver de ce côté-là.
07:24Et puis encore une fois, on va avoir des coulants variés,
07:29et la possibilité de mettre différents objectifs à l'avant.
07:33Et quand on dit objectif, c'est-à-dire qu'on peut aussi mettre des filtres si on le souhaite,
07:36on peut aussi mettre des barreaux pour pouvoir grossir,
07:38ce qui est vraiment très très utile.
07:40Donc en fait, on a une bino, un seul jeu d'oculaires qui sont déjà inclus,
07:44et on peut ensuite grossir avec différents barreaux.
07:47Et à l'inverse, si on veut réduire, il y a deux méthodes.
07:49C'est la méthode afocale, qu'on verra après,
07:51ou alors mettre des réducteurs de focale directement dessus.
07:54Et en fait, contrairement à une binoculaire classique,
07:56ici on n'a pas de problème de mise au point,
07:58c'est-à-dire qu'on va la mettre dans son télescope,
08:00et automatiquement on aura la mise au point qui sera bonne,
08:03sans avoir besoin d'aller mettre une barreau ou un OCS directement dessus,
08:08pour avoir cette mise au point et ce point focal qui sera directement parfait.
08:15Donc vraiment, l'OVNI-B, de la même façon,
08:17on peut aussi le customiser avec différentes petites couleurs.
08:20Bon, ça reste toujours assez rigolo de pouvoir encore varier,
08:24et avoir quelque chose d'un peu coloré,
08:26et pas toujours noir, noir, noir, ce qui est déjà très bien.
08:29Mais si on peut se distinguer, c'est toujours du positif.
08:33Donc retenez bien, voilà, OVNI-M, OVNI-B.
08:38Les deux vont avoir à l'intérieur un tube intensificateur,
08:42le tube OVNI-NAS Vision Astronomy Grade, que l'on développe,
08:45qui va être optimisé pour les astronomes,
08:50et qui ressemble à ce petit tube qui est ici.
08:52Alors, évidemment, il est beaucoup plus petit,
08:54c'est à peu près 4-5 cm,
08:56et on va pouvoir, avec ce tube justement,
08:58avoir différents niveaux de performance,
09:00donc les FOM, qui veut dire Figure of Merit,
09:03c'est la valeur principale pour constater les performances d'un tube.
09:08Il y en a encore plein d'autres que l'on verra par la suite.
09:10Donc ici, aujourd'hui, on a trois FOM,
09:12donc soit l'OVNI-M ou l'OVNI-B sont disponibles en trois versions.
09:15On a le FOM 2200-2400,
09:18on a également le FOM 2400-2600,
09:20et le FOM le plus performant, qui est le 2600-2800.
09:25Tous donnent, dans notre cas, une teinte monochromatique noir et blanc.
09:30C'est-à-dire que, dans votre imaginaire,
09:32peut-être que vous avez vu des films à la télévision,
09:34avec des militaires, une image verte.
09:36Nous, ce n'est pas le cas.
09:37On a une image qui est vraiment neutre, naturelle, très propre,
09:40et qui est beaucoup plus naturelle,
09:44quand on observe avec un oculaire classique.
09:46On n'a justement pas une image qui est verte,
09:49mais qui est beaucoup plus propre.
09:51Et puis, on a également différentes fonctions.
09:53Le contrôle manuel du gain,
09:54on a vu le petit bouton qui est sur l'OVNI-M et l'OVNI-B,
09:57mais le tube, lui, est également équipé de ce dispositif.
10:01On a la fonction auto-gated,
10:03qui vient protéger le tube en cas de forte intensité lumineuse.
10:06C'est utile si jamais on va pointer la lune, par exemple,
10:09ou si, par inadvertance, on a des phares de voiture
10:11qui viennent nous éclairer au moment où on observe.
10:13C'est toujours mieux de pouvoir, en tout cas, protéger son instrument.
10:16Et il faut savoir aussi qu'en termes de durée de vie,
10:19on est sur du 12 000 heures minimum.
10:21Alors, comme ça, ça ne parle pas trop.
10:23Mais 12 000 heures, ça représente 3 heures
10:25toutes les nuits pendant 10 ans.
10:27Ce que personne ne fait.
10:28Bien sûr, personne ne peut observer chaque nuit pendant 10 ans.
10:31Il neige, il pleut, on travaille.
10:33Il y a différentes raisons.
10:34Mais dit autrement, c'est 3 heures par semaine pendant 70 ans.
10:37Et ça, c'est la durée de vie minimum et non pas maximum.
10:40En fait, le tube va continuer à vivre encore plus longtemps.
10:42Mais après, il va perdre au niveau des performances,
10:44au niveau de la luminosité.
10:46Et donc, chaque tube,
10:48chaque ovni M, ovni B,
10:50est délivré avec un bulletin de contrôle
10:52qui présente toutes les performances,
10:54ce que l'on verra ensuite.
10:56Donc, voilà ce petit tube,
10:58qui est le tube OVNI Night Vision Astronomy Grade.
11:02Et il a une sensibilité,
11:04en tout cas, sa photocathode,
11:06a une sensibilité dans les longueurs d'onde
11:08entre 390 et 1000 nanomètres.
11:10Ça, c'est ce qu'on garantit.
11:12La réalité est encore un petit peu meilleure.
11:14On est plus dans les 350, 1050.
11:16En tout cas, on garantit cette partie ultraviolet,
11:19spectre visible et infrarouge.
11:21Donc vraiment, si vous comparez par rapport à l'œil humain,
11:24qui lui est sensible uniquement, c'est déjà bien,
11:26mais uniquement entre 400 et 700 nanomètres,
11:28on va avoir à la fois, du coup,
11:30une amplification du spectre visible,
11:32mais également la possibilité de voir en temps réel,
11:35ici on est tout en temps réel,
11:37de voir en temps réel des longueurs d'onde
11:39et de pouvoir les capter avec les yeux
11:41que l'on ne verrait pas autrement.
11:43Même avec un très, très gros télescope,
11:45il est impossible de voir des longueurs d'onde
11:47qui sont dans l'infrarouge ou dans l'ultraviolet.
11:49Pour cela, il faut directement utiliser
11:51un ovni M ou un ovni B
11:53pour pouvoir capter vraiment ces différences.
11:55Et c'est très, très intéressant.
11:58Ne serait-ce que les planètes, par exemple,
12:00dans les longueurs d'onde du méthane,
12:02là on les voit directement en visuel
12:04dans la longueur d'onde du méthane
12:06et qui présentent des parties
12:08qui sont plus ou moins importantes
12:10et qu'on ne verrait pas du tout
12:12avec un oculaire classique.
12:14Donc l'œil humain est capable de voir
12:16dans l'infrarouge ?
12:18Oui et non.
12:20On va retranscrire cette lumière-là
12:22dans le spectre visible.
12:24On va tout retransformer
12:26après, mais c'est une excellente question.
12:32OK, la vidéo fonctionne,
12:34donc c'est très bien.
12:36Au cas où, j'avais une solution de secours,
12:38mais elle marche directement.
12:40Donc ici, je vais vous montrer
12:42le fonctionnement du tube intensificateur.
12:44En fait, il y a trois étapes.
12:46D'abord, on a la lumière, donc les photons,
12:48qui vont être captés et qui vont traverser
12:50la photocathode.
12:52La photocathode va les transformer,
12:54et va être démultipliée
12:56environ 70 000 fois
12:58par la plaque multicano.
13:00Ça, c'est plein de petits trous
13:02dans la plaque multicano
13:04qui va permettre de multiplier ces électrons.
13:06Là, à ce niveau-là,
13:08effectivement, on est en électrons.
13:10Mais pour pouvoir être capté par l'œil humain
13:12à l'arrière, il faut pouvoir retransformer
13:14ces électrons en photons,
13:16et c'est grâce à la partie phosphore.
13:18Donc ça, c'est ce que je vous ai expliqué.
13:20Maintenant, on va le voir directement
13:22et on va commencer.
13:26Donc là, on a les photons.
13:32Les photons, en ligne droite,
13:34viennent frapper la photocathode.
13:36Donc là, ils sont transformés en électrons.
13:38Cette fois-ci, on a des électrons
13:40qui, à nouveau, restent toujours dans la ligne d'origine
13:42et viennent frapper la plaque multicano.
13:46C'est milliers de petits trous,
13:48et à chaque fois qu'ils frappent la plaque,
13:50ils sont transformés en photons.
13:54À nouveau, ils continuent leur trajectoire,
13:56toujours dans le sens d'origine,
13:58pour frapper la partie phosphore.
14:00Et c'est là qu'on peut voir plein de détails différents.
14:04Ici, naturellement, on a des photos.
14:06On ne va pas pouvoir faire une démonstration
14:08durant les RCE.
14:20Ce qui est intéressant aussi,
14:22c'est qu'on a une image qui est redressée,
14:24comme on garde vraiment
14:26l'alignement de base.
14:28On n'a pas de déformation qui va être faite.
14:34Le crabe M1.
14:36Donc, voilà, retenez vraiment ces trois étapes.
14:38Partie 1, c'est la photo cathode
14:40qui transforme les photons en électrons.
14:42Partie 2, c'est la plaque multicano
14:44qui ne va pas être transformée,
14:46qui va multiplier ces électrons.
14:48La partie 3, c'est la plaque
14:56qui transforme les protons en électrons.
14:58Partie 4, c'est la plaque
15:00qui va multiplier ces électrons.
15:02Cette fois-ci,
15:04The third part is the transformation of electrons again into photons to be visible by the human eye.
15:14We talked about it a little bit at the beginning.
15:16Each UFO is delivered with its control book, a bit like a mirror.
15:20When you have a mirror by a craftsman, you have a control book.
15:24Here, if we are on a control book for an UFO N.
15:28There are several values. Some are more important than others.
15:36The first one is the Foam, which means the figure of merit.
15:42The figure of merit is the multiplication of two other values.
15:47We have the resolution and the signal over noise.
15:50Here we have a resolution of 72.
15:56Multiplied by the signal over noise of 36.4, we get a Foam of 2621.
16:02Here, 36.4 is the noise.
16:06We have noise, but we can have a very small noise.
16:10The noise will be visible mainly when we put a narrow filter.
16:17A filter for nebulae, an H-alpha filter for example.
16:21This is where it will be more visible, but we can control it thanks to the gain control.
16:26Another important value is the contrast, EBI, Equivalent Background Illumination.
16:31This is the only value that must be the lowest possible.
16:34This value will be influenced by the temperature.
16:37The hotter it gets, the higher the value will be, which is not good.
16:40The goal is to have the lowest possible.
16:42That's why our tubes are guaranteed with extremely low EBI from the start.
16:47If you observe when it is very cold, it will be even better.
16:50If you observe when it is hot, it will be a little less good.
16:52But as it is already excellent from the start, there will not be a big influence on the observation.
16:59Then we have the luminosity.
17:01This is the number of times the photon will be amplified.
17:04The electron will be amplified and then transformed into a photon.
17:08In this specific example for this tube, we have an amplification of 62,800 times.
17:15Each UFO has its own serial number.
17:19There are other values that are important but less important than the ones I have presented to you.
17:32Now you know how the tube works.
17:34We will now see how the M UFO and the B UFO work directly in the telescope.
17:39We really have three modes of use that are all complementary.
17:42These are not gadget modes, these are not useless modes.
17:44The three modes are perfectly compatible.
17:52The visible spectrum.
17:54They have been transformed to be captured.
17:56Otherwise, we would not see them.
18:00Exactly.
18:06We put them all together.
18:08This is also why, as we have them all in one band,
18:11people who like to take pictures can also do the three colors
18:15and get the three colors and have color on the photo.
18:19We need filters.
18:21This is really the photo part.
18:23Personally, I am a visual observer.
18:26Two bases have been developed for visual observation.
18:29Then there was demand and there are people who use them for photography.
18:33They are put back in the visible spectrum.
18:37The first mode is the assembly in the foyer.
18:39It is very simple.
18:40We take our UFO, we put it in the eyepiece and we observe.
18:43It is not complicated.
18:45It is like a classic eyepiece.
18:47For this, you have the example at the top with the M UFO
18:50and at the bottom with the B UFO.
18:52In the eyepiece of a telescope.
18:54In the eyepiece of the scope.
18:56Again, it is not a telescope of eyepieces.
18:59Here it is an eyepiece of telescopes.
19:02Because with a single M UFO or a single B UFO,
19:05we will be able to put a barlow,
19:07put a focal reducer
19:09and have extremely varied magnifications.
19:14We can have very wide field
19:16thanks to the afocal method,
19:18which is the next method,
19:19which is really made for very wide field.
19:21The afocal method will consist of interlocking
19:23between the UFO and the telescope
19:25an eyepiece.
19:27Preferably, a long focal eyepiece.
19:29For example,
19:31what I recommend to everyone,
19:33is to have a 55 mm telescope
19:35with a 67 mm converter.
19:37You put this eyepiece between the UFO and the telescope
19:40and you will have very wide field.
19:42So really for nebulae,
19:44the best is to put a filter at the front
19:46to really capture these wavelengths
19:49that we would not see with the traditional eye
19:52with a classic eyepiece.
19:54And really, the afocal assembly
19:56is above all for very wide field.
19:59For everything else,
20:01it is assembly at home with Barlow
20:03to magnify as much as possible
20:05and have objects,
20:07small nebulae, small galaxies.
20:09Naturally, we will have a smaller field,
20:12but we will have a lot more objects
20:14that will still be visible.
20:16I did not go in the right direction.
20:18So the resulting focal is ...
20:20So basically,
20:22the UFO is a 26 mm,
20:24the UFO B is a 27 mm.
20:26At home, it does not change.
20:28In afocal, it is no longer the focal of the UFO that counts,
20:31it is the focal of the eyepiece.
20:33So if we take a 67 mm
20:35and we have a telescope
20:37roughly 1,300 mm
20:39divided by 67,
20:41we will have a magnification of 50 times
20:43to magnify.
20:45We started a little early,
20:47it's normal.
20:52Which telescope?
20:54In fact, all telescopes will be functional.
20:56There will not really be telescopes
20:58with which we will have problems.
21:00I want to tell you that
21:02for the visual,
21:04we have rather dobsons in general,
21:06but it does not prevent us
21:08from doing this with glasses.
21:10So here you have a Mexican user
21:12who has his UFO
21:14on a 15-inch obsession.
21:16Here we have a New Zealander
21:18who has two UFOs
21:20with an APM 150.
21:22An Australian with a small telescope
21:24who has a UFO.
21:26There we have Thierry Legault
21:28who has his UFO.
21:30Now he has his dobson 400 mm,
21:32but there he had done it
21:34with a photo lens.
21:36And then at the bottom,
21:38it is a very large telescope
21:40which has a mirror of 1.14 meters
21:42which is at the Observatory of the Provençal Baronies.
21:44And this user has his UFO
21:46which comes to put directly on it.
21:48So really we have a whole panoply of telescopes.
21:50That's why I told you
21:52it's more of a telescope eyepiece
21:54to be able to have these different magnifications
21:56with these different eyepieces.
22:00So that's really for the editing
22:02either in focal length
22:04or at the foyer.
22:06Is it that on the photos you have passed
22:08it is still not the same fields?
22:10Ah no, we do not have the same fields.
22:12Already on the one hand in relation to the telescope used.
22:14Obviously if you use a telescope
22:16of 1.15 meters.
22:18No, but it's an example.
22:20It's an example in the sense that
22:22if we really want to be the best possible
22:24we have a big telescope, a small telescope with the UFO
22:26and like that we cover absolutely all possible fields.
22:28Because if you have a super big telescope
22:30unfortunately the big nebulae
22:32you will not be able to see them
22:34even if we can have a large field
22:36despite everything we will still be limited necessarily.
22:38While with a small scope
22:40you will have more field.
22:42That's why I say a little bit both
22:44but after everyone has fun as they feel.
22:48So now that we have seen the mode at the foyer
22:50there is a third assembly
22:52which is the assembly by hand, the twin mode.
22:54That is to say that we will take our UFO
22:56we will put it on the eye and we will directly observe the sky.
22:58Basically it is delivered with a
23:00sorry
23:02Basically it is delivered with a frontal lens
23:04of 26 mm
23:06which means that 26 at the back and 26 at the front
23:08we have a magnification of 1x.
23:10But we can also change these lenses
23:12and have different lenses
23:14to increase the magnification.
23:16For example, here we are on the lens
23:18which is included for the UFO
23:20the lens which is included for the UFO.
23:22But if we want we can remove them
23:24and put lenses in 6 mounts
23:26in 42 mm
23:28in M4 third
23:30we can really have a lot of lenses
23:32with different filtering.
23:34And here for example we are on an old Cosmica
23:36in 75 mm
23:38so we are on a magnification of almost 3x
23:40and really between 1x and 3x
23:42it's totally different in terms of observation
23:44it's really very interesting to be able to compare one and the other.
23:46And again we will be able to put filters at the front
23:48and again we will be able to observe the sky
23:50in very very large
23:52with a very very large field
23:54and be able to observe the big nebulae
23:56this time directly without telescope
23:58and when I say that
24:00I think for example
24:02about NGC 7000
24:04so North America or California
24:06there are absolutely a lot
24:08and there are even times that they are not even referenced
24:10in the catalogs
24:12and that we manage to distinguish with the UFO.
24:14So really this method
24:16is not at all optional
24:18it is really very very useful
24:20if one day you have the chance
24:22often in Star Party
24:24it's extremely impressive
24:26to see in the sky all these nebulae
24:28all around us
24:30all these gas clouds
24:32Jean-Luc I remember we did it together
24:34I think that's what you remembered the most
24:36to have all these gas clouds
24:38that are present around us
24:40and that we do not see in the end
24:42the Barnard nebula
24:44which is absolutely huge
24:46it is monumental
24:48and yet we do not see it at all in the classical light
24:50and with the UFO it is very easily observable
24:52and it's gigantic
24:58I was saying that we could put all kinds of lenses
25:00so here are some examples
25:02here is a Japanese
25:04so this is not the lens
25:06what I show is that here at the back
25:08he put a small convex to be able to observe
25:10it's a very good solution
25:12but we can also put lenses
25:14Samsung, Sony
25:16here is an American
25:18Morton Harwood
25:20who observes
25:22the 4 photos
25:24he made different montages
25:26with quite original systems
25:28and to be able to rest
25:30he has his transat with his UFO
25:32and at least it is good
25:34it's a very good solution to reproduce
25:36here is a photo
25:38which belongs to me
25:40of all the slides
25:42it's a photo I made with a military lens
25:44which is quite impressive
25:46we can really adapt them
25:48on
25:50not everything
25:52but almost all lenses are compatible
25:54so this time
25:56we really have the 3 modes
25:58that we were able to present
26:00which are the home montage
26:02in AF
26:03and in twin mode
26:05now
26:07something that will concern us all
26:09is for which type of user
26:11everyone
26:13the first ones will be those who do visual observation
26:15this is really the first category
26:17when I say visual observation
26:19it's also those who will want to do drawing
26:21it's our solution
26:23and to do it
26:25we will take the 3 methods that we presented just before
26:27at home in AF
26:29or directly in twin mode
26:31so indeed during the RCE
26:33we can't do a demonstration
26:35it won't be possible
26:37so for that I invite you
26:39directly to read the magazines
26:41which will present
26:43different articles on OVNI-M
26:45we had publications in almost all magazines
26:47in many countries
26:49and in many astronomical magazines
26:51here we have Astrosurf Magazine
26:53which was
26:55T1000 OVNI-B, an extraordinary experience
26:57in Astronomy Technology Today
26:59we see the OVNI-B which was present
27:01that's in the United States
27:03I think it's in England
27:05we also have the OVNI-M which was presented
27:11then in France we have the OVNI-M
27:13which was presented in Ciel et Espace
27:15two years ago
27:17we also have Astronomy
27:19Astronomy Now, other articles also
27:23in Germany
27:25it's good to speak several languages
27:27if it's your case, it's not my case
27:29except English and French
27:31to have a maximum of information
27:33on it
27:35all these magazines
27:37are sometimes associated
27:39to articles
27:41of radio shows
27:43or Youtube
27:45you have links directly on the website
27:47of United Vision
27:49in the category Avis et Presse
27:51we also list some
27:53topics which are taken up
27:55on the forums
27:57we don't list them all
27:59it's been at least one or two years
28:01that it hasn't been updated
28:03if you go on WebAstro, AstroSurf
28:05or other foreign forums
28:07Italian, German, English, American
28:09you will find articles on the OVNI-M
28:11users who come to present
28:13their use and observations
28:19still the same, as we can't
28:21observe today or tomorrow
28:23I put here
28:25small drawings
28:27this is Peter Strock
28:29he made astro-drawings
28:31and here we are on an observation
28:33at x1 magnification
28:35without telescope
28:37only with the frontal lens
28:39and so
28:41by putting a filter at the front
28:43we will be able to bring out the nebulae
28:45M16, M8, M20, M17
28:47on the left part of the Sagittarius
28:49and then when we are at the zenith
28:51we have North America
28:53and many other small nebulae
28:55which are not necessarily
28:57referenced, but we can observe
28:59it's quite impressive
29:01and then if the heart tells us
29:03we will observe with the telescope
29:05directly these nebulae
29:07but sometimes they are very large
29:09they can even go out of the field
29:11but it's always positive
29:13to be able to see them in this way
29:15which would not be possible otherwise
29:17so we saw for the visual part
29:19now we will see for the astrophotographers
29:21this is again a category
29:23which is very specific
29:25whether it's long poses or lucky imaging
29:27we will be able to do it either with the smartphone
29:29by using the OVNI smartphone adapter
29:31it's a small accessory we offer
29:33but we also have the OVNI camera adapter
29:35which is an accessory that allows this time
29:37to connect to any type of camera
29:41or astronomy camera
29:45some examples
29:47here we have
29:49OVNI-M or OVNI-B
29:51and we see the different possible editing
29:53actually
29:55there is no better editing
29:57each one with his experience
29:59and his favorite equipment
30:01but everything is possible
30:03there is not necessarily a limit
30:05do not hesitate to test things
30:07to really find what suits
30:09each person, even if some
30:11will prefer glasses
30:13some will prefer galaxies
30:15there are really for all
30:17for all astronomers
30:19and you see
30:21everything is possible
30:23there is no better camera than another
30:25again it will also depend on what we want to observe
30:27and what we want to photograph
30:31at the level of images
30:33for example here is a German user
30:35who took pictures
30:37so we have
30:39the feet of the creation
30:41which are visible
30:43in a meter
30:45they are visible in this way
30:47directly with the OVNI
30:49and with a smaller telescope
30:51they are still easily visible
30:53being naturally a little smaller
30:55so here are two pictures
30:57that allow to illustrate
30:59on extremely short break times
31:01when we look at the top
31:03we have no arc, no flat, we have nothing
31:05it's really pictures that are stacked
31:07and on break times
31:093 minutes, 3 minutes 07
31:13without necessarily spending
31:15very long hours
31:17to photograph
31:21yes quite
31:23the halos that we will see here
31:25are a little bit amplified by the camera
31:27when we stack
31:29but we have halos on the stars
31:31that are really the brightest
31:33and we will also be able to play
31:35with the gain control
31:37to be able to attenuate them
31:39but here again it is something
31:41that is not necessarily
31:43something that we stop
31:45for a long time
31:47in any case
31:51besides we will have
31:53two other pictures
31:55North America
31:57again with the pelican
31:59and many other small nebulae
32:01that are included
32:03there Rosette on the right
32:05that's why again
32:07we are on objects that are very large
32:09so sometimes you don't necessarily
32:11have a big dobson
32:13to be able to observe them
32:15it is preferable to have a lot of fields
32:17so here on a small scope
32:19besides if I'm not mistaken
32:21I think it was a sharp star
32:23150 mm open to 2.8
32:25that he had used for these photos
32:27it will be confirmed
32:29but it seems to me that it was
32:31with this telescope that made them
32:35so naturally the objects of the deep sky
32:37that's what everyone knows
32:39there are still other things we can imagine
32:41for example we can use them for
32:43the auroras
32:45everyone has them
32:47there is a video
32:49there we are a little fat
32:51we lose a little in quality
32:53in any case the auroras
32:55will also be
32:57amplified
32:59on a phenomenon
33:01for example we have Corinne Yaya
33:03who is a French user
33:05who observed with her UFO
33:07she mentioned that it allows
33:09to increase the luminous intensity
33:11while refining the pillars
33:13and therefore to see more details
33:15we don't have the color
33:17that's actually the part in minus
33:19on the auroras
33:21but in any case we will have
33:23additional details
33:25I'm going to put the video back
33:27so we can see it a second time
33:33there is really a loss of quality
33:35at the image level
33:37which is very very large
33:41but we can still distinguish the auroras
33:43that are present
33:45come on, let's be crazy
33:47she still observed things
33:49totally incongruous
33:53these are Boreal auroras
33:55but the exact place
33:57I can't tell you
34:01it's another person
34:03it's not Corinne Yaya who comments
34:05it's associated by another person
34:11come on, let's be crazy
34:13we have the gravitational waves
34:15well, no relation to the gravitational waves
34:17but the gravitational waves are atmospheric turbulence
34:19where the atmosphere
34:21will have this turbulence phenomenon
34:23and we can distinguish them
34:25they form waves
34:27that are present
34:29it's quite impressive to observe
34:31something that we don't see
34:33with the telescope
34:35it's already too large
34:37and even with binoculars
34:39we can't distinguish them
34:41another thing, the sprites
34:43here are two American users
34:45Mike Lockwood, who is quite famous
34:47he is a famous mirror wearer in the US
34:51here is another American
34:53based in Hawaii
34:55who captured sprites
34:57they are very very brief
34:59you have to be
35:01fast enough
35:03to take a picture
35:05you let the camera
35:07shoot and then
35:09you look at the results
35:11if we want to continue
35:13in the originality
35:15we can observe the sun
35:17but in a wavelength of calcium
35:19calcium, the human eye
35:21doesn't capture at 393 nanometers
35:23but the UFO does
35:25we can observe in the visual
35:27here we have a picture
35:29the sun in this wavelength
35:31Thierry Legault
35:33did this observation
35:37I think he is the first in the world
35:39to have observed the sun
35:41so detailed in calcium
35:43I told you earlier
35:45we can do planetary
35:47here we have Saturn
35:49and Jupiter in methane
35:51and we propose
35:53the OVNI Moons and Planets filter
35:55which allows
35:57one is ultraviolet
35:59and the other is methane
36:01which allows to observe directly in visual
36:03the planets with these details
36:05it is very impressive
36:07to see them differently
36:09there is another interesting experiment
36:11with the methane filter
36:13and then we go to the ultraviolet filter
36:15in the ultraviolet
36:17we observe the moon
36:19we put the ultraviolet filter
36:21there is turbulence, it moves everywhere
36:23it moves in all directions
36:25and then we put the methane filter
36:27and the image is stable
36:29and we observe in this way
36:31directly with the eye
36:33that really in the infrared
36:35the image is clean
36:37while in the ultraviolet
36:39the image is turbulent on all sides
36:41this is something that other photographers observe
36:43but in any case in visual
36:45it was not possible to do it before
36:47and now we can see it
36:49the third category
36:51is all the scientific field
36:53whether professionals
36:55or even sometimes amateurs
36:57who want to do scientific research
36:59and space activity
37:01so there really I listed
37:03a whole range of possibilities
37:05there are still others
37:07everyone still does
37:09as he likes
37:11practices his passion in different ways
37:13so here is photometry, spectroscopy
37:15polarimetry, astrometry
37:17discovery of exoplanets and supernovas
37:19sky studies, we can really do a lot of things
37:21and then there is also the whole SDA part
37:23for all that is identification and tracking
37:25of satellites and space debris
37:27so we have different clients in this field
37:29I will introduce you to
37:33I will show you one
37:35but I will talk about two for example
37:37we work in collaboration
37:39with the University of Arizona
37:41who have a whole program of space debris surveillance
37:43so they have UFOs
37:45and here we have the two people
37:47who are in charge of the program
37:49and they also have a pretty impressive telescope
37:51of 900 millimeters
37:53it's a 36-inch
37:55we don't have the UFO on the photo
37:57but in any case with this university
37:59we have been working for a few years
38:01and they will use them to observe
38:03the satellites
38:05we also have another program in progress
38:07always with an American laboratory
38:09which is in Georgia
38:11in the United States
38:13they are specialized in all that is storm
38:15so they will use both to see sprites
38:17as I showed you earlier
38:19but also in all other phenomena
38:21TLE for example
38:23to see all other phenomena in the high earth atmosphere
38:25which are quite unusual
38:27and which will be able to be captured much more easily
38:29with the UFO
38:31and then we on our side
38:33we also have the UFO-S
38:35which is under development
38:37I would say 2025, it will be perhaps early 2026
38:39which will be the UFO really involved
38:41at the scientific level
38:43Space Surveillance Survey
38:45hence the S
38:47which will only be for the professional part
38:49there will be small differences
38:51compared to UFO-M and UFO-B
38:53but which does not affect the public
38:55as an amateur
38:57now I will also present you
38:59results at the amateur level
39:01for example here we have the Crab Pulsar
39:03this little dot that shines
39:07which is here
39:09the Crab Pulsar is extremely small
39:11it is in the Crab Nebula
39:13in M1
39:15it is a Pulsar
39:17which shines twice
39:19every 33 ms
39:21one turn of light in 33 ms
39:23and these two poles emit
39:25two Gs, one on each side
39:27so in the space of 33 ms
39:29we really have
39:31the two G expulsions
39:33and here we have the time that flows here
39:35it is extremely fast and extremely small
39:37so this image was made
39:39with an UFO-M
39:41a 600 mm telescope
39:43from Germany
39:45and I wanted to compare it
39:47to professional telescopes
39:49in extremely high-quality sites
39:51so without light pollution
39:53with big telescopes
39:55to show you the difference
39:57that can be obtained with a pro telescope
39:59without UFO and an amateur telescope
40:01with an UFO
40:03does the third video start?
40:05yes
40:13so that's it for the Crab Pulsar
40:15maybe some of you have heard about it
40:17it was made by LaPod
40:19and there were other publications
40:21later on
40:27another thing
40:29the Andromeda Parachute
40:31which is really crazy
40:33I will invite you later
40:35to go directly on the blog
40:37to see the images in better quality
40:39the Andromeda Parachute
40:41is a quadruple quasar
40:43so we have 4 gravitational lenses
40:45for the same object
40:47so we really see the 3 at the top and 1 here
40:49and it is the same quasar in the background
40:51which has been multiplied by 4
40:53in terms of observation
40:55and here I compared the observation
40:57it is the same user as before
40:59for the Crab Pulsar
41:01it is a 1m telescope
41:03based in Germany
41:05compared to the Pan-STARR
41:07which is a 1.8m telescope
41:09based in Hawaii
41:11to show you the similarity
41:13so it would be interesting to put the UFO
41:15on the Pan-STARR in Hawaii
41:17to have an even better image
41:19so that's it
41:21among the scientific part
41:23some examples
41:27then there are all the astronomy clubs
41:29the private institutions
41:31which make observations
41:33with the public
41:35which are also
41:37demanders of the UFO
41:39so here I will list you
41:41some examples
41:43maybe there are some in your region
41:45it is possible
41:47and some non-exhaustive examples
41:49of observatories and clubs
41:51with which we work in France
41:53I even had 2 abroad
41:55which are clubs
41:57and which use them
41:59to observe with the public
42:01often with a neophyte
42:03but which allows to switch
42:05from grey spots
42:07to objects which are much more defined
42:09directly
42:11live
42:13to the telescope
42:19in summary
42:21it is a bit long
42:23but I invite you to read it all
42:25you will understand
42:27the UFO is 26mm focal length
42:29it is extremely small
42:31like a classic eyepiece
42:33even smaller than some
42:35like ETOs
42:37UFO B is a 27mm binocular
42:39we are the only ones in the world
42:41to develop intensifier instruments
42:43for astronomers
42:45and so
42:473 operating modes
42:49a stellar gain of 4 magnitudes
42:51in real time
42:53we are on an analog mode
42:55very natural
42:573 wavelengths
42:59which are visible
43:01a field which is very large
43:03if we don't limit ourselves
43:05to the foyer
43:07and focus
43:09the use is very practical
43:11it is like a classic eyepiece
43:13you put it in the eyepiece
43:15and you use it
43:17all telescopes
43:19there are no limits
43:21so don't hesitate
43:23to do your own experiments
43:25everyone has preferences
43:27about telescopes
43:29objects to observe
43:31so don't hesitate
43:33and do it
43:35to finish
43:37you have the website
43:39OVNINADVISION
43:41which is directly accessible
43:43here is the first page
43:45to have more information
43:47also you have the blog
43:49it is directly on the website
43:51we can't see it
43:53it is at the top right
43:55of the screen
43:57and you have the blog
43:59you click on it
44:01and you have access
44:03to all our news
44:05we post one article per week
44:07we started on facebook
44:09we still have the facebook page
44:11but since 2 years
44:13we relay the facebook article
44:15on the website
44:17to make it accessible
44:19to everyone
44:21the third thing
44:23is that you can join
44:25the group on facebook
44:27OVNINADVISION Astronomy Official Group
44:29there are more than 600 members
44:31everyone is not a user
44:33but there are a lot
44:35we have tutorials on youtube
44:37about accessories
44:39how to use them
44:41how to improve
44:43your observations
44:45the facebook group
44:47has photos, reviews
44:49observations reports
44:51different tips
44:53to improve
44:55your use
44:57and if you have questions
44:59here we are lucky
45:01we can talk a little bit
45:03we still have a little time
45:056 minutes
45:07but you can also
45:09contact me by email
45:11to talk about it
45:13Steve Jobs, one more thing
45:15on the occasion
45:17of our 5th anniversary
45:19this month
45:21we are offering
45:23for the first time
45:25a 500€ discount
45:27on all models
45:29for all orders
45:31before the end of november
45:33thank you for listening
45:35and if you have questions
45:43at the beginning
45:45there were a lot of numbers
45:471800, 2000, 2400
45:49what does it mean?
45:51the different performance levels
45:53the 1800, 2100
45:55we don't do it anymore
45:57now we start at a level of 2200
45:59even higher
46:01this is the calculation
46:03between the resolution
46:05and the signal on noise
46:07the higher it is
46:09the better it is
46:11so we start at 7000€
46:13on the OVNI M and 8000€ on the OVNI B
46:19any other questions?
46:21when we work with Lunal
46:23you said it was suitable
46:25for all models
46:27we still have
46:29the interest to make sure
46:31that we have a very well corrected
46:33with the chromatic
46:35so that given the importance
46:37of the spec
46:39it will be ultraviolet
46:41for the infrared
46:43we are more strictly limited
46:45to the visible
46:47there are two things
46:49better will be the instrument
46:51better will be the observation
46:53and also it is interesting
46:55to have an eyepiece
46:57that is sensitive to the infrared
46:59and ultraviolet
47:01and many are reduced
47:03in the visible spectrum
47:05and we have the BBHS
47:072000nm
47:09this one is excellent
47:11it allows to improve the observation
