Seagull nebula

Recently I had managed to work out all the issues with my guiding setup (with some minor differential flexure), and hence I had more confidence that the images I capture would come out all with pinpoint stars. As it was nicely placed in the sky, I decided to image the Seagull nebula (IC2177).

Imaging settings:

ASI178MM cooled to -25 degrees C, Gain 200 3 min subs

Red: Astronomik 12nm H-alpha 20 x 3 min subs

Green: Astronomik 12nm O-III 20 x 3 min subs

Blue: Astronomik 12nm S-II 20 x 3 min subs

Seagull nebula - RGB stack of H-alpha, O-III & S-II

To me the Seagull nebula looks more like a pteradactyl. This is probably the best stacked image I have produced so far. Can’t wait to do even more imaging.
