The hourglass effect is due to the pixels on the edge of the field having a vignetted view of the telescope aperture (aperture looks like an almond or oval) which diffraction of that shape aperture causes the hour glass shape in the star profile. Nice video!
Hi Nico, I just wanted to show appreciation for your sense of experimentation in your videos. I know the body cap lens didn't do too well but it was cool testing it to see what happened...astro with a camera body cap :D
That's pretty cool. I just picked up an 800mm F11 myself with the intent of trying to capture the moon close up near the horizon. I didn't think it'd be any good for anything else but I was very surprised by the nebula photos. Thanks!
Wow The canon 800 mm performed better than what I expected if I would to try it on something It will definitely be M33 or M31 if you could squeeze it in with the full frame sensor. Great job I love the Idea of trying with whatever gear or equipment you got.
Super useful vid Nico! Looking to do a similar setup as the RF 800 (Sigma 150-600 instead) and with a SA GTi on order. What plate are you using to mount the uniguide to? Can't seem to find any products that do this! Saw you used something similar in your GTi review too...thanks!
I'm just getting into astrophotography and being in Southern California is rough with all the light polution. From my backyard I get like maybe 2-4 stars.. and every place around me that i'd be able to film stars/the Milky Way is so far that if I do decide to bring all my gear I have to make it a day trip.
Hey mate, I'm from Australia and am new to astrophotography. Just want to thank you for your content, it's has been such a fantastic help and is so inspiring. Thank you, you're a bloody legend!! 👊
so,i use every day Tamron 150-600mm lens. 150-300 is F5.pass that is F6.3. I was wondering if its any good and should i bother to get tracker. Seems like i shall give it a try. Thanks mate.
I have the Sigma 150-600 and it works quite well for astro. It's about 4.25 pounds (1.9 Kg) I think the Tamron is a very similar lens. Took some practice to use it all out at 600mm but lately been getting some nice galaxy pics.
Love your work and images. Have used a lot of your ideas in imaging and processing and have had some success. Just wondering if you have ever tried a Mirror type lens and whether they would be useful in Astrophotography.
Hey Nico, fun comparison! Thanks for sharing! Would you consider the 800mm on Messier 99? It's such a pretty galaxy and I never see anyone trying to capture it!
I have a suggestion of a good target to shoot with the 800mm rf lens. The hockey stick 🏒 and whale 🐳 galaxy. It should it in the fov pretty well. Clear skies!
I am amazed of the amount of colour the R5 has achieved. Is your camera modified? Great video, thanks for sharing. I am really interested in what the R5 in combination with the 800mm can deliver.
Another wierd, or more like crazy lens I would like to see used for astro is the insane SIGMONSTER 200-500 f2.8 but it costs as much as a decent car, so how someone would want a such overprised OTA, I am not sure of. And the weight is also quite compareable to a beefy Newtonian
Cool! Just got my RF 600 day before yesterday (refurb+on sale=crazy deal!). Guess I'm going to have to play with it at night. I think the next targets for you galaxy-wise should be the Leo Triplet, M81and M82, and of course M31.
Tamron SP 500 or nikon 500mm mirror lenses are among the best for this. F/8 is slow but manageable. Stay away from the opteka/samyang/etc mirror lenses
Wait for the moon to go down and try it out on M81 or M101. M81 would be the better target, being quite a bit brighter overall. You should be able to get 82 in the FoV as well, by the looks of the M8/M20 shot. I'd even have a go at the Cygnus Loop, but you may not get it all in the FoV of that lens.
I think "Mini Andromeda" NGC 7331 in Pegasus would be a great target! I don't see a lot of people attempt it. Also The Sombrero Galaxy would be awsome. Can they be photographed within reason with that F11 lens?
Interesting video. Low F ratio's are in vogue these days.. but it does have some short comings. Your 800mm did a lot better than I expected. If your able to do narrowband, or maybe dual NB with an L-Extreme type filter on a modded cam/astro cam.. the Crescent nebula would be an interesting target for that lens.
Funny. I got today the RF 800mm F11 2nd hand. The moon was just too perfect today, didnt get any nice shot of an animal yet but the moon was easy - even handheld! after stacking the 4k (crop!) Video which basically fills the entire vertical space im wondering how detailed the moon will be
The Results From 800mm lens Is Really Good. Loved The Detailed Walkthrough on the Video! You Could Try Using It on Galaxies or Globular, Im curious How it Would Be The Results :)
what mount did you use for the 800mm? I think I understand the point of the scope and camera, but wonder if you need specific mounts (and also how to mount a regular camera/lens on that vs telescope)
I used a big equatorial mount (sky-watcher eq6r), but you could do it on something much smaller since the lens is lightweight. To mount it you just need a universal dovetail plate and some screws.
I'm pretty impressed with the results of the 800mm, but I still wouldn't buy it. Okay, it's very light, but F11 is not what I'm aiming for. One question: did you use a modified DSLR or was it a "standard" camera?
@Nebula Photos you lucky guy got a "Ra", tried to get one, unfortunately too late, but it is sold out WORLDWIDE. Now I will wait a few weeks (months), then I will get my R7 astromodified. Then I can also use my EF-S lenses with my "clip-in filters". So **** happy! Clear Skies, keep up the good work. How about testing DSO's with a "Holga lens", that's weird squared too ;-D
Hello me again to I’m getting a ts optic Apochromatic refractor AP 80/480 CF-APO f/6 FPL55 Triplet OTA For guide scope should I get the 40mm svbony or the 50mm uniguide
Honestly doesn't make lot of sense to me, it is an expensive lens (even though not super expensive) and it's f/11, for that price you'd better go for some short apo refractor and if needed put a a Barlow lens on it, you'll get a more versatile setup for similar price and with probably a better quality.
From a value perspective a telescope would be better, but I disagree about Barlow. Usable field of view with a Barlow is really bad, forget full-frame or even APS-C without signficant vignette and distortion. What is impressive about this lens for the price is how good the corners looked with a full frame sensor.
The f/11 lens is never going to produce sharp stars. Image spot size with a perfect f/11 lens and perfect star will be bigger than 14μm , but the Canon Ra provides 5.36μm pixels. So every star is going to be a blur of about 3x3 pixels area at best. Lens and sensor must have equal MTF to be optimal. The Ra sensor is a poor design on Canon's part with the tiny pixels. It's gotten out of hand with cameras having sensors that no lenses can resolve. This just produces noise and blur.
Lots of people that follow this channel dabble in many different kinds of photography and may wonder how the lenses they already own for a different purpose will work on the stars. I didn't have high expectations, but was very pleasently surprised by how well the Canon RF800 did. If it had been a disaster, I would have likely scrapped the video. I couldn't find any images of long exposure deep sky work with this lens, so I hope it may be helpful to people wondering. If it was a purchase decision, knowing it can be used for astro might help inform that decision.
I think Nico's point is . Anyone showing an interest in astrophotography, should try out the equipment they already own before splashing out on expensive gear. At the very least, it may teach them which lenses are not suitable and where to invest their hard earned cash.
That was the whole point of the video as Nico CLEARLY STATED. He bought them for other purposes and he showed how amazing the results can be with lenses you ALREADY HAVE! Great job, Nico❤️❤️❤️❤️❤️
The hourglass effect is due to the pixels on the edge of the field having a vignetted view of the telescope aperture (aperture looks like an almond or oval) which diffraction of that shape aperture causes the hour glass shape in the star profile. Nice video!
I would like to see m51 the whirlpool galaxy with that canon lens.
@Poketronics--btw, my DJ name is HourGlassDJ 😎😉🤘🏻🍻🇺🇸🇩🇪
Hi Nico, I just wanted to show appreciation for your sense of experimentation in your videos. I know the body cap lens didn't do too well but it was cool testing it to see what happened...astro with a camera body cap :D
Thanks Chris! Glad you liked it
I use a 400mm f/5.6 with a teleconverter fairly often, so 800 f/11 is right up my alley!
That's pretty cool. I just picked up an 800mm F11 myself with the intent of trying to capture the moon close up near the horizon. I didn't think it'd be any good for anything else but I was very surprised by the nebula photos. Thanks!

Hi Nico, you have trailing issues on your shirt, please polar align your outfit next time!
Love your content! Ciao from Italy
As the 5min sub did so well, I’d love to see what a 10min sub would look like on a fainter target. Perhaps tight on the Elephant’s Trunk Nebula.
Nico you are the fun leader…. Seriously this was fun to watch
Ha, Thanks Daniel!
Great video as usual. For the 5 minute exposure, what ISO did you pick?
Super useful vid Nico! Looking to do a similar setup as the RF 800 (Sigma 150-600 instead) and with a SA GTi on order. What plate are you using to mount the uniguide to? Can't seem to find any products that do this! Saw you used something similar in your GTi review too...thanks!

Hi Nico, just wanted to bring to your attention that the polar alignment was way off when taking stars pictures for your shirt. Regards

Thank you for all the help/knowledge! Might I suggest Andromeda if it's in your current sky? I'll be watching and listening!
andromeda is far too big for a 800mm.
Love your work and images. Have used a lot of your ideas in imaging and processing and have had some success. Just wondering if you have ever tried a Mirror type lens and whether they would be useful in Astrophotography.
Try using the RF800 on M57 - bright, small, and interesting!
Hi Nico, great experiment how about trying the 800mm on M13
Hey Nico, fun comparison! Thanks for sharing! Would you consider the 800mm on Messier 99? It's such a pretty galaxy and I never see anyone trying to capture it!
That little pancake lens really surprised me. Great shot of the milky-way!
Do a full hour exposure!
planetary nebula would be cool!
With 800mm it will be interesting to see M51 or M104, but may be M87 may show it's jet? 🤔
Anyway, it is pleasure to watch your videos!😊
I have a suggestion of a good target to shoot with the 800mm rf lens. The hockey stick 🏒 and whale 🐳 galaxy. It should it in the fov pretty well. Clear skies!
you should try the big lens on the dumbbell nebula or the whirlpool galaxy or the hercules cluster
I am amazed of the amount of colour the R5 has achieved. Is your camera modified? Great video, thanks for sharing. I am really interested in what the R5 in combination with the 800mm can deliver.
I use the Canon Ra, which comes 'pre modified' to let in the Ha and give that boost to the reds.
Nico, can you review the new TTArtisan 500mm F6.3 when it comes out?
Definitely M101. Perfect size for 800 mm with some surrounding space, and still conveniently placed if you get out there before 1am.
Try the rf 800mm f11 on The Orion Nebula. 👍
Are there any new videos with the RF800/11 used for astrophotography yet? I'm curious :)
Can you try whirlpool galaxy or sombrero galaxy, and try the helix nebula if you can? 😃
Great, you have many interesting ideas for new video.
have you made more shots with the 800mm after this video?
Another wierd, or more like crazy lens I would like to see used for astro is the insane SIGMONSTER 200-500 f2.8 but it costs as much as a decent car, so how someone would want a such overprised OTA, I am not sure of. And the weight is also quite compareable to a beefy Newtonian
you need a crazy equatoriale mount to load this sigma lens !
@@telemaq76 the EQ6-R would carry it fine I would think, as the lens "only" weighs 16kg
That lens is very soft @ 500mm f2.8
Cool! Just got my RF 600 day before yesterday (refurb+on sale=crazy deal!). Guess I'm going to have to play with it at night. I think the next targets for you galaxy-wise should be the Leo Triplet, M81and M82, and of course M31.
Hello Nico! Will you by chance be attending the Okie-Tex star party at the end of September? If so, see you there!
Hello Nico thank you for the video, I wonder if the cheap 600mm f/8 Opteka lens works for deep space astrophoto, did you used before?
Tamron SP 500 or nikon 500mm mirror lenses are among the best for this. F/8 is slow but manageable. Stay away from the opteka/samyang/etc mirror lenses
@@AdmiralSym Thank you!!
In my experience, f8 mirror lens works as f10
As people always say dont zoom in, get closer. Probably this one is an exception.
Was that a Cygnus tattoo, Nico :D ?
Well spotted ;)
Caldwell 19 with the 800mm im trying it with my Tamron 150 500mm with a Sony a7iv and with a zv-e10 which is a 750mm equivalent..fingers crossed:)
You should try the 800mm on M51.
I should look at using that 800 with my Z6II with a adapter. You could try M33 with it. As always thanks for sharing Nico
Try Andromeda galaxy with RF800 mm Lens sir
Wait for the moon to go down and try it out on M81 or M101. M81 would be the better target, being quite a bit brighter overall.

Well.. then again maybe not. Small aperture.. NB.. probably wouldn't work well at F11.. but it might be a fun experiment anyway. 10-15 min subs :)
So you use 5min expose time with 800mm lens ? So when you should use rule of 500 ?
When shooting without tracking and a wide angle lens (Milky Way shooting)? This was done with a tracking mount.
@@NebulaPhotos thanks for reply.
give a try to m27, maybe M57, small but very light. M101, M51 can be good target at 800 !!
Ever tried a mirror lens?
do you recommend lenses or refractors for deep space astrophotography?
Funny. I got today the RF 800mm F11 2nd hand.
The moon was just too perfect today, didnt get any nice shot of an animal yet but the moon was easy - even handheld!

@@Pip8oy I have an R7 on order too. Think we'll see them before the end of the year? I'm not optimistic.
Is your EOS R camera Astro modified?
Yes, it’s the Canon Ra - the version of the Canon R that came pre-modified by Canon.
Hello me again to I’m getting a ts optic Apochromatic refractor AP 80/480 CF-APO f/6 FPL55 Triplet OTA For guide scope should I get the 40mm svbony or the 50mm uniguide
30mm svbony I mean
Go for the 50mm Uniguide, excellent guidescope!
Ok
Hi, what focal lenght and aperture of a lens do you suggest to a new?
The Samyang 135mm f/2 is great, and if you add a star tracker it will be even better.
Do you have a link for buying the 18mm
myfunleader.com/products/funleader-caplens-for-mirrorless-camera I bought it from here, and it took a couple weeks to arrive.
haha, i thought the lens in your right hand was a lens cover! doh
That's pretty damn good for an f11 lens
Leo Triplet Next!
Nice

Soy usuario de CanonRF 800. Un lente a un precio asequible. Aunque obscuro.
Whirpool galaxy😊
Small one looks like something you’d put your drinks on
please do some more on the 800mm. I was hoping to try to get that lens and eventually get a star tracker to try it out.
M51
