Here we have the region around Gamma Cassiopeia. Gamma Cass. is the star at the top center and you can see two bright but small nebulae, IC59 and IC63, right next to it. A much fainter but larger nebula can be seen stretching to the bottom of the frame. To the best of my knowledge this faint nebula is Sh2-185.
To go this deep, I had to go 'all in', requiring 3x3 binning and thus a big loss in resolution. I'm very happy with the result though. Especially when considering that this was shot at 55mm aperture.
