Description

The crescent nebula and the fainter Soap Bubble Nebula. Same telescope that I have used to photograph this previously but what a difference the astro mono-camera and filters make.  Nebula is H-O-O. Stars are RGB. 180 minutes of Ha (45x240) and 280 minutes of OIII (70x240)

Description: I used the Bill Shanhan/ Mike Cranfield Narrowband Normalization Process in PI to push back the OIII a bit more to let more of the H-alpha shine through.
