imaged the Blinking (Halifax)

The BGO 'bot also photographed NGC 6826. A planetary nebula in Cygnus. One of the RASC Finest NGCs. Also known as the Blinking Planetary. And Caldwell 15. Neat! Unfortunately, there's a focus issue... or a planar issue, noticeable on the left edge of the frame.

Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, GIMP. North is up; left is east.

I didn't notice it at first but on the right edge of the frame, above (north) of the star GSC 03565-0243, there's a small round fuzzy: galaxy PGC 63573. Possibly an elliptical. Or a compact spiral.
