The Crescent and the Soap Bubble in Cygnus. From Pier 13 data shared with Pier 14 Syndicates. RGB H-alpha and Oxygen III Exposure times were 60s x 60 each in RGB, 180s x 120 in Ha, 227 x 180s in OIII, giving a total integration time used was just over 21 hours. Processed with Pixinsight and Photoshop.
I love the faint wisps of OIII around 34 Cyg near the bottom of the frame.
Thanks for looking
