Yes, of course, Sonya.

A big jump in processing ability came with CS. One was able to utilize many features in 16 bit that were only available in 8 bit with version 7 but, even so, even the lower versions still work well.

M51 reprocessed

The good news is that the slight bit of color noise is gone from the first version,
the bad news is that the dust that was visible in the first version got swallowed by your black point.
I thought the color was excellent in the first version, but this looks even better.
My regards,

Hi Maurice,
I'm pretty sure that this isn't the source of your problem, but under Color Settings/Color Management Policies/ RGB: try choosing Preserve Embedded Profiles.

You've made a good case for that with your image, Louie.
You've chosen a good field of view, too.

That's a good image for such a short exposure, David, and the color looks to be right on.
If you're up for a real challenge, this nebula has a dim, crazy outer nebulosity that's rarely imaged.
Stan Moore has a fine shot of it on his site:

I tried for it last year but I ran out of time before I got an acceptable image.

First completely unattended image -- vdB142

Posted By dan kowall
An absolutely stunning image, Tom. You've mixed the Ha in well with not a hint of salmon color.
The square stars are a little disconcerting, but I read on another group how you're going to get rid of the secondary vanes so that will change that. How are you planning on supporting the secondary with your modification?
Congratulations on the M13 APOD, too!
My regards,

Another oldy but goodie?

Natural processing with great star colors, Jason.
Easy to like, but not so easy to do.
