Seagull Nebula – IC2177
Seagull Nebula
So this image was with the worst data ever… about 1 hour worth of shooting, when I need about 25 hours worth of data. But got bored and processed the data and it ended up having some really good pieces to it and the light came out pretty good. I shot it really low through atmosphere, so lots of noise was hard to remove, but looking forward to getting more time on the target should make the dust lanes really stand out.
