Iris in the Dust

Here is NGC 7023 in a somewhat wider field in an effort to try to expose some of the dust in the region. It is processed up a bit high to highlight the dust. This was kind of a fun catch with a simple setup on the humble CG5 Goto mount and a homemade guide scope. A full size image is here:

I also have a 2006 image of the Iris up close:

Hey Jim, the dust really shows well and the color works nicely.

Thanks for the comments guys.

I am beginning to appreciate that different subject matter can suggest variations to your "normal" processing workflow. PS Actions and other automation tends to perpetuate the routines. I am glad I tried a few different things with saturation, levels and filters on this one.
