Description

Data on two different nights in april - last one April 27th so this is more of a 50th birthday present for me. Due to the different nights including meridian flips and repositioning (finding a new guidestar with OAG), there are many partially-overlapping batches of frames. The resulting common picture is this crop of all overlaps, reduced to 40% of the full image scale. Stars are not really round need to check the frames.

No flats, I have flats but need to get my head around stacking batches of lights with associated flats

Description: Stacked without frames that contained egg-shaped stars :-) this resulted in 17 frames instead of 20
