Whatever you are doing... keep it up!

Thanks for sharing!

I see you upgraded the mount already. Are you still using the Atik ATK-16? Your M27 looks really good. You gotta love H-Alpha and light pollution. They just go together.

Great job, David!
Your manual guiding worked well and you haven't clipped your black point (like many of us do).
Try stretching your data more, though. You want to fill up as many of those 256 histogram slots that are available.
Attached is a quick stretch of your data. I'm sure that you could do better with the original data, but it shows that you have some good data lurking there.

I would suggest that you eliminate the (median?) filtering that has produced the strange artifacts in the image.

Programs like MaximDL have really great processing tools that can bring out just about everything that you can capture. I know Maxim is expensive, but it is really worth it. The images that get downloaded from the camera are not altered during the download, and the latest version will store the image at a very high bit level. There are numerous stretching routines that can be applied to make the image look its best. Highly recomended over every other software I have ever used.
