collected photons on omega And (Halifax)

BGO imaged ω (omega) Andromedae aka BU 999 using the star GSC 03265-2190. I was hoping to split the C and D elements? First viewed this target on 30 Aug '19.

multi-star system omega And in luminance

Luminance only, ½ second subexposures, 12 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

Ha. Look at that. C and D, at a north-west through south-east angle are easily resolved, despite the poor image quality. Curiously, SkyTools draws the stars in a east-west orientation but the CD data in the Object Information panel shows a PA of 140°. A and B are merged.
