What a fantastic video. When someone knows their subject it shows. Thanks.

Your astro-equipment review videos are TOP NOTCH! I'm planning to purchase my first dedicated astro camera and these videos are indispensable. Thank you so much for all your hard work and great explanations, Wido.

This was a great video, with excellent examples. Thank you for demystifying this subject. I really learned a lot.

Very helpful Wido for what can be a complicated subject. Your channel and several others helped me settle on a ASI 2600 MC Pro for DSOs and the 178 MC for planetary and lunar. One of these days I’ll also try out my full frame, mirrorless DSLR. For the amount of time I can dedicate to astrophotography, I went with colour cameras. No regrets. They do an amazing job.

Thanks Brian! I use similar cameras, the 178 for moon and planetary and a 2600mm for deep-sky. And I still have an older asi1600 pro. Hope you'll have some clear skies in Canada!

Great video Wido!

Small correction: the number of pixels does determine the resolution but it doesn't determine the FOV. The sensor size determines the FOV.

I use a Canon 6D unmod for deep sky. Just started with my first pics. M81/M82 and M101. Now nights are too short. I‘m thinking about color vs mono and zwo2600 vs zwo294 later. But first good picture processing is my goal. Thanks for your interesting videos and inspiration!

Thanks Dirk, that's a good strategy!

Great video Wido, you are steadily getting better not only at astrophotography but also at conveying precise and cristal clear information in your video (but please ditch this ugly green screen). I would also point out that a high dynamic range is especially crucial if you leave in light polluted area since the more precise encoding will help you extract the faint signal of the astronomical object from the huge background noise of light pollution. I recently upgraded my 533 MC Pro (14 bits) to a 2600 MC Pro (16 bits). While the differences between the 2 cameras were noticeable when I shot from the dark skies of southern France, they were simply breathtaking when I imaged from my mother in law’s residence, in downtown Douai, in the highly light polluted skies of northern France. And the 533 is already a vert good camera ! Another minor point you should mention is that you should check that the imaging field of view of your telescope can cover the whole sensor size: for instance, the Celestron Edge HD 8 cannot cover the entire field of a full frame sensor, even with a focal reducer. By the way, in your next video, do not forget to mention the weight of the camera: it can be a signifiant issue if you are using a star tracker.

It's very deep knowlege of camera, great video. I have canon dslr with original ir filter removed and using a clip filter for cls with uv/ir cut I do interested in qhy533c, please include that in your next video.

One thing you skipped over is diffraction. Depending on the f/ratio, the minimal meaningful pixel size is not only limited by seeing, it's also limited by the relationship of focal length and aperture. Diffraction limits the useful pixel size for most telescopes to fairly big values. For example, an f/8 scope can't really use pixels smaller than 5 um, regardless of whether that's below an arcsecond or not.

Great video! Thank you for this. Guess I screwed up when I bought my 8'' dob, with 1200 focal lengh, and thought that I could later upgrade it to do some astrophotography... Back to the drawing board... :)

Thank you.... it appears that there is a ton of commitment necessary to do deep sky photography effectively. I love the results but the learning is more extensive and the equipment is more expensive than I am willing to commit. I will need to be satisfied taking tracked Milky Way images with interesting foregrounds.

Yes, it does require a lot of energy and time. Lunar and planetary is perhaps an option as they are easier to capture. And widefield astro pictures are great too!

Many thanks for this great video. I would like to point out that, if I am not mistaken, the dynamic range is not determined by the a/d convertor. The dynamic range in EV is the difference between the darkest and the brightest that a sensor can discern (black level and the amount of light that causes full saturation of the pixels, above which all will be just white independent of further increase in light intensity, sort of clipping). The a/d convertor will determine how many different steps will be present within the dynamic range of the sensor. Sorry, can not think of a better way of explaining this but I might be wrong anyway.

Very cool I really hated using the cellphone adapter on our telescope. It's too bad there wasn't a link for top ten best budget telescope cameras.

Hi Frank, I'm using an asi178 for planetary imaging and an asi1600MM pro with the celestron .7 reducer for deep-sky astrophotography. Works pretty well for me. The imaging scale is .55, but you can apply binning to rescale your pictures to about 1 arcsec p/pixel. Hope this helps :-), clear skies!

Great video, thanks for making this. One thing that confuses me is imaging scale in regards to high magnification moon imaging. I've seen some amazingly detailed images come from gear that by the numbers would be significantly oversampled. For instance, a C8 SCT using a 2x Barlow and camera with a pixel pitch of around 3.5um. Is the rule of thumb for image scale different for lunar photography?

@AstroForumSpace

Yes, it's like planetary imaging. You can go as far as 0.25 or even 0.1 arcseconds per pixel under good seeing conditions.

Your opinion about the Mallincam DS 16c for astrophotography ?

Hahah, from the thumbnail I was like, wow 5 cameras....pause...thinking...ok, I only have 4... 5 is just excessive ;) .... thinks.... You know, I need a cooled OSC.

Everyone starts with modified a dslr. They are great, but you'll end up with more noise in your pictures as they are uncooled cameras. Dark frames and dithering helps, but if you want the highest quality pictures you'll eventually take the step towards a dedicated, cooled astrocamera.

I am not familiar with astrophotography but to me it seems like vibrations from a cooling fan in the camera could be a problem. Is this a problem? Do they use special high precision fans or vibration dampers?

Hi Lars, good question. I own several cooled cameras, they all came with a 2 Stage thermo electric cooler. None of them have any vibration issues, multi minute exposures show nice round stars.

@@AstroForumSpace Just speaking from personal experience with ZWO, I had owned several ZWO camera's before one had an issue and they refused for 3 months to RMA it, Only after selling it for a severely reduced price and posting on their social media several times about this issue did they finally want to acknowledge this issue and do something about it which was too late. So I make sure now I warn people before they buy ZWO just because they are budget friendly. Equipment lottery in astrophotography is not acceptable. Our gear costs way to much to hopefully get the good gear an not lemons "gear with problems" Needless to say I do not own anything ZWO anymore after the horrible customer service I received from them. Now all of my camera's are QHY whose got amazing customer service
