A narrowband bicolour image of the Rosette Nebula using hydrogen alpha and oxygen-III filters. Total exposure time was 5.5 hours. This was processed as a Ha:sG:OIII image using a technique developed by Steve Cannistra. I’m just getting the hang of the processing technique but I’m pleased with these early results!
