re-framed Pac-Man (Halifax)

BGO shot a field centred on star TYC 3663 00635 1. This is near the middle of the Pac-Man Nebula and open cluster NGC 281. I wanted to reframe the shot from the first run on 8 August. It worked. Unfortunately, it looks like there's a bit of a gradient on the bottom edge.

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


I also gathered narrowband data.
