M42 from 09/01/2011 reprocessed

I had posted it yesterday here already:

http://stargazerslounge.com/imaging-deep-sky/124755-yet-another-first-m42-sorry.html

but I had to post it again as I have reprocessed it with some extra light frames that I had forgotten about. When I started imaging that night I had the capturing destination in APT set to camera only. A few frames later I changed it to PC + Camera but later I had forgotten about the frames that were only on the camera.

So I have re-processed with an extra 21x 60 sec frames in the stack bringing the total to about 50 minutes. And what a difference this has made !!

At the end of the session I thought I'd take a few frames of the Alnitak region. I got 20x 40 sec exposures (about 13 Minutes). Not expecting much I processed it anyway and was quite stunned by the result. I can see quite a bit of detail in the Flame Nebula and I can even see the outlines of the Horsehead!!

They are both very nice captures' nicely caught of B33.Mark

They are good results. It is especially pleasing to capture somthing that is not visible to the naked eye. I am also on this learning curve and am amazed as to the long times needed to get a good image.
