The Crescent and the Soap Bubble

[peter shah]

The Crescent and the Soap Bubble in Cygnus. I imaged this one in RGB H-alpha and Oxygen III remotely from Spain with the AG14 Newtonian and the FLI Kepler 4040 CMOS. Exposure times were 60s x 60 each in RGB, 180s x 120 in Ha, 227 x 180s in OIII,  giving a total integration time of 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

Although I have seen the Crescent Neb I have never heard of the Soap Bubble although I have picked it up in the map D1 of the Interstellarum atlas. Really brilliant photo - well done.

Thank you Mark, ...It was only discovered a few years back.....I remember the rumbles in the community at the time...I finally got around to imaging it. Its extremely faint and mostly visible in OIII.

Lovely clear soap bubble.🤗

What bandwidth are the narrowband filters you are using?

Amazing, this soap bubble defies laws of nebulae I have seen before in a sense that it is too perfectly circular.

Excellent picture Peter. The soap bubble in particular stands out very nicely.

Thank you Roy....I tried to keep it as natural as possible as narrow band can do strange things to RGB
