M1

You've got some good star colors in there, Brian. I equalized your black points and the star colors were more noticeable (see attached image).
You could use two other strategies to make them more intense:
---Process two different versions of your image, one for optimizing the nebula and the other for preserving star colors, then layer the best of each together.
---Early on in your processing with levels and curves, stop when the star colors lood good, select them out, process until the nebula looks good, and then feather.
You have some good detail in your M 1.
Good job.

Hi Eric,
It looks pretty good so far. Most imagers skip the luminance when shooting globulars, and just do RGB 1x1. You might want to try that with your data.

That's an amazing amount of detail from a C8, Jim. Very impressive.

That's an appealing, natural processing, Alan. It's not overly sharpened or contrasty. You have an artist's touch.

Horse and Flame with Borg 77ED

I think that you did better than you think, Vincent.
First of all, you have some real good data there.
You're right in thinking that 6 hours of images should have been enough. I did a little stretching of your image and have attached the before and after result. I'm sure that you could do better with the original master.

Thanks, guys.
Klaus, You're right, this camera and scope were made for each other. They both highlight the best capabilities of the other.
Jose, I wish the stars were tight, but at full resolution I can see the field rotation that I'm getting from a less than adequate polar alignment. I'm closing in on it, though.
