After a few months waiting for it, I finally got to play with my new telescope and I revisited The Orion Nebula (M42). This time, I could include the Running Man Nebula as well (NGC 1977). Their light took roughly 1500 years to cross space and hit the sensor of my camera. I am very pleased as I could gather much more information this time. Considering that the moon was 97% illuminated yesterday night, I didn’t think I could be able to salvage these details. Looking forward to some clear and dark nights.
For those interested in the technical details, this is a stack of the best 50% of 78 light frames, stacked with 20 dark frames (used to reduce the heat noise from long exposures), 20 flat frames (to reduce vignetting and dust), as well as 20 bias frames (used to detect camera noise and dead pixels). The camera is an EOS 550d modified for astrophotography.
Taking the photos was the quick part (fortunately as it was just about to freeze last night). A couple of computer hours were necessary to bring all the details out.
