This was my last chance at seriously taking images of the Winter Constellations. My weather this Winter has truly been "wonderful" to say the least... Anyways, since I was a little rusty, I decided to take another shot at the Orion Constellation. I had 3 nights of no moon, and no clouds. Perfect weather to get some serious time on a subject. I was pretty happy with the way this turned out. Especially with the star colors as well as with the amount of hydrogen-alpha emissions that I managed to collect. This is my best Orion Image to date.
