Description

The Soap Bubble in Cygnus turned out to be a tough customer. Even with the focal reducer bringing my C14 down to about f/7.7, the bubble is barely visible on stretched 15 minute sub-exposures in Ha and OIII. The plus side is that the final image revealed the variability in thickness, color, and fringing of the bubble's outline.

I hope you like it!
