M42

M42 is otherwise known as the famous Great Orion Nebula. This shot includes the adjacent M43 and Running Man nebula. It was my first attempt at a marriage between an H36 H-alpha image and an M25C one-shot RGB image. The Ha image was taken from my backyard in the mag 3 skies of Orlando and the RGB was shot from Chiefland's Astro Village with the 10" Newt at f/3!
