How to Connect a Camera to a Telescope | Smartphone, DSLR, Mirrorless, Dedicated Astronomy

[@leonardfibigerlewis]

I have watched tons of these tutorials but none of them left me with a confident understanding in this field. Yours on the other hand has invitingly opened the mental door I always wished open and left me wanting to pursue more in the matter. Thank you, I muchly appreciate your informative channel. Hugs from Sunny South-Africa.

[@mazze4782]

Wow. Finally a professional and good "overview" of different methods on how to connect cameras with a telescope - this helped me a lot. Thank you so much for the effort. One suggestion: I guess the Video Speed is 1,25 x than u recorded. Since i am from Germany and its hard to follow fast speaking americans in technical language i switched to 0.75 x speed :) Go on! I like it.

[@AstroDenny]

This was a cool video and something I could have used when I first started! I will say that if you're going to hook up a camera to a refractor for prime focus, you will likely need a lot more spacers than you may think! Unless it's called an astrograph, they need to make up for the surprising length the diagonal adds! Looking forward to more content!

Hi Sarah what is better for close up pics of the moon? Negative projection or eyepiece profection?

[@archivemanager2734]

Hello. I have also used telescope eyepieces that have a thread near the viewing lens, this thread allows attaching to an adapter tube that attaches to the camera. It makes the eyepiece centrally align with the cameras sensor and so removes any annoying light path offset or wobble. I have also used something similar to allow people who have Fixed-lenses cameras to screw their complete camera+lens units onto the eyepiece adapter and attach to the telescope, they took some moon photos and were very happy.

[@SarahMathsAstro]

Hello there, were the threaded eyepieces from Baader? Those are really neat and make a ton of sense. I hadn’t heard of the threaded fixed-lens camera adapter though, I’ll have to look into that. Very cool! Thanks for sharing!

[@demej00]

Thank you for this video. I bought a Celestron 5" Newtonian Reflector telescope about a week ago and haven't been able to point it at much of anything in the sky because of near constant clouds.

[@johndaley9188]

What method do I use, actually none. Yes, I'm still learning. But, to almost answer your question, when the time comes, I will be using a dedicated telescope camera. When I saw your notification pop up, I was hoping to see something with your edgehd. Sadly, it was only used as back ground candy. As always, your videos are entertaining and informative. Do you still have the AM5? Kind of related, would you recommend using the .7X reducer for DSO. Is there a situation where you would not want to use it? Thank you.

[@SarahMathsAstro]

I had included the EdgeHD in the video for attaching a T-Ring to it as those T-Rings are much different physically than the more traditional ones, but I ended up cutting that part out since it was a very specific use case and I was trying to keep this a little bit more broad (still hard to do with so many possible configurations within each method though). I do still have the AM5 though. And as far as the .7x reducer for the EdgeHD and DSO imaging, I do use it. I wouldn't use it for planetary imaging, unless I was trying to get a super wide-field view of a planetary conjunction or all of Jupiter's moons or something similar. Great question. Thanks for taking the time to watch and thanks for the kind words. It's much appreciated. I hope all is well!

I am happy with my Dwarf II and ASI Seestar S50 which, however, are not appropriate for planetary photographs. Is there any not so expensive telescope or telescop equipment including. goto mount that is able to shoot good planetary objects and DSOs? Maybe a modular one, with different focal lengths?

[@SarahMathsAstro]

I'm happy to hear that you're enjoying your Dwarf II and Seestar S50. They are both great devices. As far as a non-expensive and modular planetary setup, the least expensive option that comes to mind is a Newtonian that has a native focal ratio of f/5 or faster. Maybe the Orion 8" f/4 Newtonian Reflector Astrograph - 800mm focal length + a coma corrector to correct for coma. Then for planetary imaging, you can pair it with a 2x or 2.5x Barlow and a planetary camera to increase the focal ratio and focal length. www.telescope.com/Orion/Orion-8-f4-Newtonian-Reflector-Astrograph/rc/2160/p/133615.uts You'd need a sturdy equatorial tracking mount as well for long exposures for DSOs. All together, you probably are looking at $2k USD on the cheaper side of it. But purchasing second-hand is something worth looking into too. CloudyNight is an excellent place to look!

[@fy7589]

Hey Sarah, I am a beginner wildlife photographer. Recently with my long lens, I started photographing the moon and the planets. The moon is pretty good but the planets are ultimately soft and bad. I know about pipp and autostakkert and registax and astrosurface and whatnot. I know all about astrophotography in terms of image stacking etc as I am a software dev who wrote a prepriotary image processing and stacking software for a company. Whatever, my question is, would you pick up the 9.25" edge hd or the 11" cpc xlt? The mount on the 11" is better but the optics I heard for the 9.25" is better. But at 2800 mm or 5600mm vs 2350mm and 4700mm, if that is negledable, if the chroma end the edge sharpness is negledable, I'll pick up the 11" cpc instead of 9.25" edge hd with avx mount. Which one would you pick? My goal is planetary imaging but I''ll also do deep sky nebula imaging too. I want to get as much versatility as possible. Which one really would you pick up? Does the edge HD offer really that much extra over the bigger cpc? I have by the way a ton of lenses from 800mm to 14mm, like 20 lenses both prime and zoom, a lot of teleconverters (barlow extender lenses) and also speedbosters (barlow reducer lenses) and multiple cameras, both dslr and mirrorless and also even film cameras so I have been there in terms of photography and videography for years and yet I still want to do more. I want to get to the astrophotography edge now. I have nothing in terms of astrophotography camera but I wanna buy a scope that I'll connect my canon eos camera and shoot the Jupiter with high detail and stack the video frames with astrosurface. I am sure that I can do better than what I could do so far with my existing normal camera lenses even if I get a 6" scope but I want to go big this time, and the biggest I can order is the 11" non edge hd, there literally is no edge hd 11" that I can order in here Turkey, But I still have 5-6 months until I get the place the setup the observatory for it, However the 14" may never come to stock, so that's why I'm asking, if you say f, everthing just get a 14" edge hd if you can, I'll try to get it from overseas and it'll be expensive but still I wait for your opinon. I have had a terrific experience with my current gear for wildlife and birding but for astro imaging, I need more. Thanks and my highest appreciation if that means anything. Still, please give me your opinion. I'll shoot a video hailing you. Thanks!

[@SarahMathsAstro]

Hey there, it comes down to how steady your skies are that you're going to be imaging from really. If the skies can even handle that level of focal length, and imaging the planets is what you want, then more focal length tends to be best. The EdgeHD series is nice because of the coating but I don't have direct experience with the CPC to say if I've noticed any sort of difference comparatively. Ultimately, I'd just make sure you have the right sampling and the right skies for imaging at such high focal lengths or else the whole setup is basically useless. Hope this helps!

[@fy7589]

@@SarahMathsAstro Thank you for the response, I'm not really hoping for a perfect weather condition for astro shooting as I can do lucky imaging with the mount even for days if not weeks of exposure with the observatory I'll be building (a roof that's openable) so I think I'll get the longest possible scope, probably the 14" edge hd. And on those scopes the front secondary mirror is detachable to connect the camera and turn the scope into a RASA style scope at F/2 and much shorter focal length. But the coating you mentioned on the EDGE HD series really helped me decide which one to get despite the size. Thank you so much!

[@SarahMathsAstro]

@fy7589 awesome! I think adding the Hyperstar configuration to the EdgeHD series is a great combo for doing both types of imaging (long exposures and lucky imaging) very excited for you and wish you all the best!!

This video is VERY informative and thank you for doing this. I recently acquired a ZWOASI662MC for usage with my dobsonian. I have a 12 inch dobsonian. When I go to take a photo with a 2x Barlow, i get a reflection of the ZWO camera's sensor in the photo. Am I doing something wrong when its with the barlow lense?

[@SarahMathsAstro]

It may be that the telescope is out of focus and/or the placement of the barlow lens to the telescope and camera may need to be adjusted to get everything in focus to eliminate the apparent reflection. The spacing between everything, that is. This would be my first guess as to why there appears to be a reflection.

you may also need to collimate your telescope, too if you haven't done that already.

Maybe remote in the future after getting a good tripod and am good at setups. Big request but thanks for sharing

[@SarahMathsAstro]

Hi there, I've not used or put together a setup using advanced encoders so I probably am not the best person to respond to this. Perhaps reaching out to a local observatory might be better e.g., a local astronomy club with an observatory who may use similar-type encoders.

What's the difference between afocal projection and positive projection? Unfortunately, because the video is corrupted between 3:44 to 3:59, which is explanation of what is afocal projection, it's unclear how it differs from positive projection. Thank you!

[@SarahMathsAstro]

I apologize for that. Afocal projection is where we use a camera with a lens attached to it and hold it over the eyepiece of an afocal optical system (like a telescope). There are two focal planes with this method; the first is the telescope's original focal plane with the eyepiece placed slightly after it so that an image can be seen through the eyepiece (how we normally observe through the eyepiece with our human eye). Then, instead of using our human eye to observe the exiting light from the eyepiece, we hold a camera lens over the eyepiece that then converges the light onto the second focal plane, the camera sensor. By aligning the camera lens and camera sensor perpendicular to the optical axis, we would get the focused image so that we could then take a photo or short video. Eyepiece projection is different in that a no additional camera lens is attached in the imaging train. Instead, the camera is attached directly to the eyepiece, usually via a T-Ring adapter and an eyepiece projection adapter holding the eyepiece. The eyepiece is placed slightly after the telescope's native focal plane (similar to what we saw with afocal projection) but instead of having the exiting light go through to a camera lens, the eyepiece projects that light directly onto the camera sensor. How close or far away the sensor is to the eyepiece determines the magnification. This way, there is only one focal plane, rather than two like we saw with afocal projection. This creates a magnified image based on the distance between the camera sensor and the eyepiece. Hope this helps! Again, sorry for the issue! -Sarah

[@aranelchan]

Ah, I see. I have been happily observing Jupiter and Saturn through my 10 cm refractor, so I tried imaging using prime focus, but Jupiter turned out to be a tiny bright blob. That got me thinking about eyepiece projection, and when you introduced afocal projection, that sounded like it, so I was confused when you then introduced eyepiece projection 😂 But it's clear now, thanks! I do have another question though: is that eyepiece adapter tube necessary, or could I just use my straight through observing configuration for my telescope (i.e., I can achieve focus for observing with those existing extension tubes without using my diagonal)?

[@SarahMathsAstro]

@@aranelchan that totally makes sense! They do seem quite similar. I would recommend an eyepiece projection adapter. But if your eyepiece has T-threads at the top of it where you can thread it into a T-Ring on your camera, then you might be good to go. especially if using a refractor. If you're not able to reach focus still, then move the eyepiece further in or further out of the focuser. The other nice bit about the eyepiece projection adapter, particularly one that you can adjust in size/ extension (I think the one I linked in the description is adjustable), is getting the eyepiece closer or further away to the camera's sensor for more or less magnification. But yes, give it a go without one if your eyepiece has threads on the top. I'm curious to hear how it goes. 😀

is it possible to use a telescope as "normal" lens? like having a 1000+mm lens instead of expensive normal lense

[@SarahMathsAstro]

Yes, it’s possible if you’re using a DSLR / Mirrorless camera or dedicated astronomy camera. The prime focus method (the second method we cover in this video) covers what you need :)

The Celestron XYZadapter is falling out of favor with me. The clamp seldom holds well, due to the weight of the phone, and the adjustments knobs need constant adjustment to keep them from loosening up making it a very unstable platform. Also, depending upon the eye piece, the clamp cant keep up a decent hold. I have used the adapter for years, years of frustration, and feel it is a diservice to suggest it. Just my opinion. I used to feel it worked great. But it takes a lot of fiddling with and in dark skies, I have punted on even attempting to fix any issues that come up. A lot of cameras now have multiple cameras, and adjusting to a new camera at night is difficult. I do use a red light to beam down the telescope to find a decent placement for the camera over the eyepiece, but again, doing all of the adjustments is time consuming, and frustrating when the clamp also need major adjustments on its hold, depending upon the eyepiece. In other words, I set it all up, and it is just too unstable to remain in place.

[@superdave0002]

Hi Sarah in your videos your always saying "mirrorless camera" I have a nikon 3400 with a mirror. Will it still work the same when connected to a telescope? Thanks David

[@SarahMathsAstro]

Hi Dave! Great question, yes, your DSLR will still work connecting it to a telescope (granted like any camera, you'll still need to have the right connection/ attachment accessories) and depending on the type of telescope you have. For connecting your camera via the prime focus method, you'll want to make sure you have a t-ring to mount to your specific camera's lens mount and be sure you have one that fits your specific camera brand/ make/ and model. If you're trying to attach your camera directly into the focuser tube of the telescope with locking screws to secure the camera in place, you'll also need a t-adapter/ prime focus/ nose piece adapter to thread onto the t-ring that is mounted to your camera's lens flange that I mentioned earlier. Then, you'll take the nose piece/ t-adapter and put it into the focuser tube and secure it in place. If it's with a refractor, you shouldn't have any issue with achieving focus. But if you're using a newtonian or dobsonian that wasn't made specifically for astrophotography, you may have issues with a DSLR (a camera with a mirror inside) when trying to achieve focus with the telescope since the sensor sits too far back for most of those telescope's to achieve focus. DSLRs and mirrorless cameras have different flange focal distance requirements which is what informs the width of the t-ring for the different styles of camera's. Mirrorless cameras' t-rings will be much thicker than a DSLR's t-ring as a result. See here: briansmith.com/flange-focal-distance-guide/ There are lots of ways around the issues that DSLRs tend to have with non-astrophotography dobsonians/ newtonian depending on your specific situation (focuser travel, focuser size, etc)., but that will require some homework to figure that out for your specific telescope model. It could be as simple as buying a low profile t-ring adapter for the DSLR instead of the traditional t-ring that's about 10-11mm in width. Or, you may have to do some more invasive work to the telescope. CloudyNights.com would be able to point you in a good direction. Alternatively, if your telescope has threads on the focuser or you have a field flattener, or reducer/ flattener, or coma corrector installed on the focuser, then the camera facing side of those accessories will already have threads on there and you just have to make sure that the thread pitch size and the aperture diameter of the t-ring fits that optical accessory. Hope this helps!

How do I focus when I mount the DLSR to a telescope?

[@SarahMathsAstro]

You'll want to either turn on the live view screen on the back of your DSLR or look through the viewfinder while you move the focus knobs of your telescope forward and/or backwards until you see the stars get smaller and smaller. Just make sure the focuser isn't locked. There may be a tension screw that needs to be released depending on your telescope. I find it's most helpful to focus on a bright star or Jupiter or on the edge of the Moon to get some nice contrast. Your DSLR may also have the ability to digitally zoom in 5x, 10x, or maybe even 30x which is very helpful when focusing. Once the stars/ Jupiter or the Moon is in focus, you can exit out of the digital zoom mode. You'll then want to lock your focuser once in focus if there is a tension knob as mentioned earlier.
