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.

RASC Finest The Blinking Planetary nebula luminance

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.
