processed NGC 147

Cranked out, thanks to Ian W, a final luminance image from CCDStack v2. I was pretty happy with the results, particularly given how faint, diffuse, and dim the target NGC 147 was. This was from data collected on the evening of 4 Sep.

This extremely faint object, described as a dwarf spheroidal galaxy, is also called Caldwell 17.
