NGC247 is part of the Sculptor group of galaxies, only 11Mly away but with a very low surface brightness. Nicknamed the 'Needles Eye Galaxy', this intermediate spiral galaxy is viewed almost edge-one and has quite an interesting shape with its distinct 'hole' possibly caused by collision with a dark subhalo and continued restriction on new star formation in this area.

Captured here with around 14hrs of data from my B7 backyard location. It's taken a couple of months to get enough moonless nights, but seeing conditions were generally very poor, and I needed to throw out quite a bit. Some nice dark sky data would really help to bring out the multitude of background fuzzies in particular the fascinating string of galaxies right on the edge of my fov.
EDIT: Managed to come across a bunch of data I'd already acquired on this object earlier in the year! Done a full repro with double the data - bit of a difference ay?!?
