In this video, I go out to a Bortle 2 zone with a friend and image the cloud complex known as Rho Ophiuchi, rising along with the Milky Way band. I use a Samyang 135mm f/2 for the first time, attached to a Canon Ra and tracking the sky with an Atlas EQ-G mount, and spend several hours on the target.

Respect for anyone who shoots in the desert! Great image, too!
The video we have always wanted but are not worthy of! I am super pumped to see final image!
Wow. That photo looks like a masterpiece.
Great Video and Image!! Rho Ophuchi Looks Like an Intresting Target!! Lovely Colours in your Image!!👏👏
Always an interesting adventure watching your videos. Totally envious of your desert location, says the fellow from a Bortle 8 place.
Awesome outcome and cool vid. Thank you !..
Great images and lots of fun. Rho will definitely be worth revisiting again and again! Totally jealous as we’ve had nothing but clouds for 3 months here in Santa Fe New Mexico. Coincidently the first night with reasonable lack of clouds two days ago I chose Rho Ophi and a Nikon 180 2.8. New subdivision construction to our southwest is creating new light pollution dome. Will need to travel to a Bortle 3 or better to catch the dark dust lanes of Rho Ophi. Looking forward to your final images!! Wish I were there!
This was so much fun shooting! 🔭. Amazing video!
really really Nice!!! Clear skies!
I thoroughly enjoyed this post. I am planning on buying the Samyang/Rokinon f/2 . It's an awesome lens. New subscriber!
Another lens I have had some good results in bortle 8-9 skies with is the Mitakon 135mm F2.8 lens. It is a completely manual lens and the camera does not even think it has a lens. It is a budget lens for under 200 dollars. It might be a good starter lens for someone tight on funds. I love the thing.
(A quick update, I do have to crop the images with my full frame camera due to vignetting with the lens wide open. Not so much with my crop sensor camera.)
Gorgeous!
애쓰셔서 촬영하신 영상 잘 보고 갑니다 고생 많이 하셨습니다
Looks awesome!
Superb!
Im currently shooting Rho with the Rokinon/Samyang 50mm. at first I thought the lens was garbage, but stopped down to F/3 its great. I also have the 135 and love it. Use it almost every time out. Of course I have the 14mm for milkyway shots. I really enjoy using their lenses and they really perform well during the day also!
I'll try the Samyang 135mm for wide-field EAA. My idea is to really get to know the bigger views and the context around all the galaxies and nebula I can only see in detail with a bigger telescope like a 8 inch newtonian I normally use. Great to hear the Samyang 135mm works so fine. It will reduce the capture time for EAA even more.
I still want to get the 135mm Samyang lens for my Canon EOS Ra. I will get the EF version because I have the R to EF Adapter. I have the 12mm for Fujifilm and the 14mm for the Sony. ❤

Great photo!! I have an off brand oshiro 135mm(f2.8) that is awesome (bought for less than 200$) I do most of my astrophotography with it now over all my other lenses. I will be upgrading to an EQ6-R pro and some more focal length/first telescope in the near future.
Clear skies
Nice vidieo. Your fan from india. loving galattic hunter 🙏
Wow, that's a really good shot of Rho Ophiuchi, the amount of dust you got is amazing. The Roki 135 f2 really is a beast at AP and stars without needing to be stopped down, I hope you get a lot of use out of that lens. Also I would love to see you use it with the 1600mm and mono filters, I've seen really cool results with that type of rig.
Thank you! I might try to get an adapter for the QHY600M but sounds like it will be a pain so not sure :D
@@GalacticHunter yeah, backspacing can be a pain when you mix lenses with dedicated cooled cameras, but I think QHY makes an adapter set, I’m not sure since I have a zwo camera with efw to ef lens adapters and those adapters will probably also fit on QHY depending on the M threads. But even with a dslr(or mirror less) I wish you luck, that’s a really fun lens from what I hear.
Lovely video Antoine! I do like this nebula region, unfortunately is very low in the sky from my home. I am thinking the small star trails that you had could be because of balancing, having good balance with a dslr and lens can be harder.
Try to jump up to 2.8, it will give you less work and even sharper images. Just a tip. I want to shoot this Rho, but in my place in Norway, the summer are so bright in jun- beginning of aug, that the view of RHO is gone. I live up North, almost like the same as Trevor from Astrobackyard. It is nice to see more and more people joining her also, we astro folks need to grow, because this is the most beautiful hobby in the world. Clearski.
Interesting, I'll have to give f2.8 a try, thanks!
I stop it down to f2.8. Easier to nail focus and tighter stars. Great lens
500 likes here. thank for the fun time.
Mention to your friend that took the M81/M82 pics that dark flats should cure that little bit of amp glow on the right. I made the same mistake (until recently) with my 183MC of not using them. Now my images are completely free of amp glow.
Wish I could take some night pics. Damn California wild fires has stopped me for a 2nd year in a row now. Can't see the stars because of the smoke haze.
Great video! I am going out tonight (Majorca Euro time) to shoot this with the 135mm, QQ I have a crop sensor Astro modded, Canon 700D - checking the filed of view is difficult will I get all of this in with the Blue HH ? Thanks !!! Simon
Just curious - are you working with an astromodified camera or a "regular" one?
...orange juice with cereal?! I must try this
Was this a canon mount lens or were you using an adapter? if so which?
Great image. Do you have a video of the post processing of this image? It looks amazing.
I have heard there is considerable flaring around the brighter stars on that 135mm lens. Can you confirm this please?
Great video! When I started building my first astrophoto rig a year ago, this is the lens that I wanted, but they were on backorder everywhere (something that I eventually got used to). I ended up buying a RedCat instead, and love it, but I'd still love to pick up this lens sometime for great shots like what you collected here. Thanks for all of the great videos!
Maybe im being a bit special but how did he not have star trails without a proper alignment?
The alignment was good, just not "extremely precise". The lens is much wider than a telescope so star trails aren't visible with that exposure time if you're a bit off in the alignment.
Have you tried the canon 135mm @ f/2? If so, how does it compare?
Haven't tried that lens, too pricy 💀
magnifique
It's like a RASA but small,easy to use and cheaper.
Wonder is the sampling of the stars affected by the Ra pixel size. Maybe try the 135 with the zwo?
Bonjours Antoine bien dommage que ce ne soit plus en français c était un plaisir de regarder vos vidéos vraiment dommage
Did you say 2-3 hours for M107? why so long. Isn't a modern Sony light sensitive enough to shoot video of the stars? so how could it require more than a second or a minute of exposure. I assume that 135mm doesn't need stacking? Is Sony A7IV not better than Canon EOS RA?
Also maybe do 4k videos. When you have 4k displays it's just worlds apart in youtube. And they are neglecting HD bandwidth on top of the resolution difference.
My experience with Rokinon/Samyang wasn't as good. I got the 14mm f/2.8 for Nikon Z mount and fully open even at the center the stars had nasty coma like distortion. I had to stop down to f/5.6 to get rid of it and at that point I could just use the Nikon 14-30mm f/4 lens anyway. But it was a super cheap lens, maybe they put more effort into this one.
You should take off the camera strap next time to avoid camera shake when wind gusts are there... cheers
Good idea thanks!
Why does everyone use ball heads? >.< They can slip during the night for starters.
if you're using an appropriate payload and tighten it properly there's no issue. It also adds a great convenience vs controlling RA and DEC.
Unless I'm mistaken, it's so he can track like an equatorial without guiding.
In this case, for framing too. Can't rotate camera otherwise, need some rings for the lens.
@@falubii9712 using an appropriate payload is only mildly relevant. Temperature change can cause things to slip.
@@gooe9561 the mount tracks the sky with or without guiding. That's how an equitorial mount works. Ball heads are used by people for framing purposes, because they can't figure out how to make it work with RA/DEC
Ver nice, what was the ISO again, I think you stated 6400.
Супер 👏 🙌 !!!!!
Amazing result, did you also took some flat images? Because i also have this lens on my canon 6d and i have big issues with vignetting.
No flats, surprisingly there wasn't any vignetting
@@GalacticHunter oh crazy to hear.
Nice! How did you use the mount for Tracking? You just set it at random star for tracking and pointed the ball head in a different direction? Maybe i missed somerhing…thanksw
i think he got lucky
He must have polar aligned, I think the random star part was just tricking the mount to think he went through the autoguiding feature without any actual guiding. In my experience even at 50mm you gotta polar align pretty well to get 3 min subs.
Lets assume it is polar aligned. Then I can point at any star with the mount and Track and at the time point in another direction using the ballhead?
@@kaeseonline When you polar align, the mount is pointed to the pole, everything in the sky revolves around the pole so you can point your ballhead and camera anywhere in the sky and the mount will (by simply rotating) track it.
Thanks. I polar aligned the mount, then "faked" the star alignment process through the hand controller so that the mount starts to actually engage the gears to track the sky, then yes I just aimed the camera to the target. Once it's tracking you can aim anywhere :)
you should remove the strap on the camera. if there is a breeze. it will shake the image. been there, got the T-shirt.
I was saying the same thing, lol. kept thinking he was going to tie it up at least
@@Tim_the_Astronurd I also add a motorcycle disc lock alarm to my rigs if sleep is involved...
@@davejenkins8524 I cant shoot from home, so I have to pack up around 3:30am and drive back, so Im sitting with my rigs in the middle of a field. theres a good amount of wildlife that can kill a person, so I always have the 1911 45 on the hip. JIC
Thank you! I should have indeed!
Ça fait 2ans, t'es pas là maintenant?

?
Question?
Was your dslr modified or stock?
He used a Canon Ra. It is the factory astro version of the mirrorless EOS R.
superbe tu avais déjà prévu de la faire il y a quelque année quand vous faisiez encore des vidéo en Français et la paf une bonne réussite par contre la bouffe ma pas l aire d etre appétissantes je sais pas la bouffe francaise te manque pas un peu coq au vin, boeuf carotte, gigot ,Hachi parmentier ect alle bon ciel a vous
Merci ! Et oui effectivement la bouffe me manque enormément. Je vais en France pendant 2 mois dans quelques semaines donc je suis impatient de me régaler :)
@@GalacticHunter et bien bonne appétit pour toi
