You've answered a question burning at the back of my pea sized brain, I have an astro-trac I'm yet to get out and play and Orion (M42) is my primary target. I have plenty of images taken through my 8" RC using from memory maybe my D810 (or maybe a small astro camera, I honestly don't remember) but I've been trying to decide on exactly which lens I want to use for the target and I have a nice older 80-200 f2.8ED, 16 element Nikon lens in with all of my other junk which I purchased new in 91.
Though if the camera doesn't come back from the repair centre soon it will be on my Player one Neptune (178 colour sensor, again, I think) in which case I may go to my Samyong 135mm f1.4. Once the moon dies down a little and health improves.
The 650D is an APS-C sensor isn't it?
In which case my 80-200 will be fine on my player one camera, better on my Nikon eventually, hopefully.

Hey Leo,
Yes the 650D is APS-C. I reckon this would be a good experiment with your camaras. Personally, I would use the Player One camara as those sensors while have a high readout noise, the Quantum Efficiency of them would be better. Furthermore, as there is no LPF filter, it would allow Ha to come through better on the images. However there would be a compromise. The small FOV of the 178 would make tracking important and finding M42 would be harder due to the FOV. This would be a fun little thing to do with the rokinon 135. I'm quite a fan of large DSOs being done with small sensors/high focal lengths
