The Sculptor Galaxy is about 11.4 million light years away, and features a supermassive black hole in its centre of some 5 million solar masses! Vello describes the two shots:
I've been trying to get a good image of NGC 253 for about a month now.
Still have not figured out how to combine the channels without getting artifacts, but this is half decent, I think.
The colour image is from data acquired in reasonable seeing, and the higher-res luminance is from last month.
