Here is an RGB + Ha rendering of Orion and Eastern Monocerous. I captured some of the Ha data last year. The rest of the Ha and RGB frames were taken about a week ago. I used eight 30 minute Ha frames and about the same number of five minute RGB subs. All were taken with a 55 mm Pentax 67 lens attached to a Finger Lakes Instruments CFW-7 wheel, PDF focuser and Microline ML 110002M camera.
I personally like the contrast of the brilliant golden Betelgeuse with icy blue Rigel in this shot. I pushed the Ha pretty hard to bring out the faint nebulosity between Barnard's Loop and M42 and in other areas. There is plenty of distortion in the corners, but what the heck, it's a 36 x 24 degree field!
A full size jpeg version is here:

Unfortunately, the full size image seems to lose some snap when converting from the huge 16 bit tiff to a fairly compressed jpeg. My ISP only supports 8M uploads and the original is 60M!
Anyway, I hope you like it.
