DSS can do that. I used shots from the c8 with reducer at f6.3 and an f8 refractor with and without the reducer using the same camera DNG files loaded straight in to DSS , using 100% of images in mosaic mode and a few darks from each session. No flats of course. I have been playing with this for a while, tweaking DSS, and when I saw the posts regarding camera arrays as a valid astronomical technique it seemed worth more attention.
It is logical that DSS simply stretches and rotates the images , the same as PS alignment, to line up the stars and remove varied lense distortions so it all matches. There must be a limit. I suppose for some small objects perfect frame alignment , matching optics and no rotation would be preferable. For a cropped field it does not seem critical.
I wonder how much time is right for some of these small objects. Is 10 or 20 minutes required?
