Tim An interesting link which brings out some conflicting advice (as usual with this type of thread). I have done OK with the Celestron C8 SCT. According to the Astronomy Tools CCD Suitability Calculator the C8 with my cameras leads to slight over-sampling which becomes worse with the addition of th...

Good to hear you have sorted out your problem. Systematic capturing of calibration frames and an understanding of the histogram are big steps in producing decent images.

I purchased the book linked to in post #14 - a very useful read. Having thought about a project like this, a few things come to mind: Moving location, maybe a different latitude would alter the mount elevation. Tracking, polar alignment during the day. Take all the gear to some location other than t...

Alejandro Downloaded the files and the outstanding item seems to be the difference in gain settings between the light (=0) and dark (=100) frames. As a general guideline I set the exposure, gain & brightness for the light frames, keep these exact settings for the dark frames and adjust only the ...

If you have them, it would be helpful if you could post somewhere on the internet a light, dark & flat frame (1 of each) for download and inspection.

Jerry Some alternatives to GoSkyWatch https://alternativeto.net/software/goskywatch-planetarium/?platform=android . determine whether or not the dovetail on the scope is directly in line with the C8 axis You state you switched to the AM5 mount. On your previous mount, did it work correctly with the ...

Jerry GoSkyWatch https://gosoftworks.com/apps/goskywatch/ on iPhone/iPad. There is a $0 version. The image below was captured on my iPhone whilst sat in my armchair, pointing the phone at a wall at 15:00. I think the app is iPhone only? There might be similar planetarium software available for other...
