Description

Revisiting the Cygnus Constellation to image this 6 panel mosaic over the course of two months. I've shot multiple data sets from multiple places, utilizing the West Texas Skies for the all important LRGB data and the light polluted skies of Chattanooga for the Hydrogen and Oxygen.

Thanks for looking!

Description: Adjusted curves to control the reds a bit. In my fear of the blues, I went a bit too far.
