Constellation Imaging

I had to give this a shot to see how it would look, so I centered the scope on Orion and shot a sequence of 10 shots of Orion at 3 minutes, 55mm at f/5.6 and ISO 1600, and then selected the best 5 images to stack with Deep Sky Stacker for a total of 15 minutes of integration time. I've been advancing with my processing technique's having finally learned how to adjust some of the levels and obtain decent contrast and color, and this is evident in the results with Betelgeuse (upper left) and Rigel (lower right) showing some proper colors. In the larger image there is some red nebulosity visible in M42, the center star in the sword of Orion, although, as expected, the whole nebula is a little "blown out." This one has been a good learning experience and demonstrates some progress in what I am learning.
