This is another example of using alt/az setup with No guiding, by using 400 subs the curved/egg shaped stars seem to round out well after stacking in DSS, I think more subs would make it better, the processing in Startools brings out some fine detail, this is also my 1st attempt at using subs at multiple iso settings.

200 x 25sec subs at iso 1600 with 50 Darks and 50 Bias
