Description

I added the Sii integration to my previous bi-color effort. I ran into some cloud issues and had to toss a lot of my Sii frames.

I think it is OK but I'm not thrilled with the stars and I think this may have been over manipulated a bit... I do think, however, the stars are better than the previous image.

The take-away on this project is that it is probably better to err on the side of conservatism on most aspects of post processing.

As always, criticism and/or comments appreciated!

CS,

Mike

Description: Still having bad luck with Arizona weather... It's crazy! When I'm available, it's cloudy, when I'm working it's clear. Oh well, it's the astrophotographer's lament. So I took the opportunity to tune this one up a little. Mostly to improve the stars and background.
