A preview to see if it is still worth for taking flats for this set of data.
Comet E3 taken with DIY 6" F4 Newtonian + Vixen coma corrector PH + 100Da in YL last night @570mm 3.8
Single shot of 15s exposure @iso800, unguided with Vixen SXD2

Re: Comet E3 -- stacked version
Seems the final image is improved a bit after stacking with more subs and flat calibrated in DSS.
total integration of exposure = 65x15s
Processed in PI and PS
