tried NGC 281 again (Halifax)

Shot the Pac-Man Nebula (NGC 281) again, aimed at TYC 36630 06351. I was hoping to avoid gradient and satellites in the colour data...

Pac-Man in luminance

Luminance frame at 30 seconds and 10 subexposures. FITS Liberator and Paint.NET. North is up and left is right.

Finally got some good LUM data! No nasty gradient at the bottom. No airplanes. No satellites. No tumblers. Pretty good registration. I'll take it.

I had last worked on this object in August 2016.
