M42 Orion Nebula in RGB + Narrowband
The Hancock & D'Arienzo team presents Andy's D'Arienzo's version of M42, The Orion Nebula in the constellation Orion. Andy shot 3 hours and 40 minutes of hydrogen alpha + 3.5 hours of 0III using his FLI ML8300 Mono CCD on his TMB92SS Refractor at F4.4 from the Waning Crescent Observatory in Long Island New York, while I shot 2.5 hours of RGB using the Canon 5D Mark II at F7 on the TMB 130 Refractor from the DownUnder Observatory in Fremont, Michigan.
We each do our own processing when it comes to combining and post processing in photoshop using slightly different techniques and it gives me great pleasure to post Andy's version and a different perspective combining narrow band imaging with RGB on one of the most photographed and spectacular Nebulae in the winter night sky.
We hope you like this version.
