Bubble Nebula, NGC 7635

One last dim target before the stormy weather sets in again. Happy to present this more improved shot of the "bubble", an emission nebula in the constellation of Cassiopeia located near star 4 Cassiopeiae and open cluster M52.

Unguided, 400 x 15 sec. JPEG frames, 100 minutes of accumulated exposure, 1600 ISO, calibrated and such, processed with DDP. No stretching.
