Description

M13
Dec 26, 2014
C11 on CG5 unguided
Canon 7D
12 x 30 sec lights, ISO 640
10 X 30 sec darks, ISO 800 (jacked that one up)
10 bias

Flats made it weird. So processed the lights in Photoshop to remove the vignetting. Didn't have the LP filter on and had a horrible green cast that I finally removed by making this B&W. :)
