Second night in a row...
The Burke-Gaffney Observatory robot imaged multi-star system 41 Aquarii, aka H N 56, aiming at GSC 06384 00537. I observed this system on 15 Aug '15 but did not make good notes. It is listed in the RASC Observer's Handbook in the Coloured Doubles table.
Luminance only, 0.5 second subexposures, 20 stacked shots. FITS Liberator, GIMP. North is up; east is left.
The A and B stars are merged in the image. If I had to guess, I'd say B is the bump on the left or east edge of A. SkyTools 3 Pro says they are 5.1 arc-seconds apart. This is the limit of the BGO Apogee system given the delta magnitude.
C and D are to the north-east. D is the delicate star west of C, ever so slightly to the south. ST3P quotes the sep. at 12.0".
Lovely. Finally, I have good positional notes.
