Description

I'm trying a new processing procedure to produce a quasi LRGB image:

1. open dark and flat corrected fits image in CCD ops, smooth and size.

2, go to utility-single shot color-extract channels-luminance.

3, color process luminance image as save as L tiff.

4 .Stack L tiffs with RGB tiffs for final image.

5. Do post processing in photoshop.
