Hi Sandy
Generally, a camera designed specifically for auto guiding may not be ideally suited to long duration exposure astro photography, say 30 sec to 60 sec exposures.
If the camera is not designed for long duration (e.g. 30+ secs) astro photography, then any exposure of over, say 3 to 5 seconds will begin to show objectionable noise. This can be removed via dark frames.
Another requirement would be for the camera control software to be able to save the individual frames in a suitable format for reducing, then aligning and stacking?
So, I’d be looking at the maximum length of exposure and can the camera control software save individual frames in a suitable format and also take dark frames easily.
Cheers
Dennis
