M13 in full LRGB was created by DaveGrennan
While I was out watching perseids on Friday night. I took this image of M13 with the ATIK 16HR and a bright moon in the sky. It is my first full LRGB image with this camera. The moonlight showed up as noise in the green channel. A darker night would yield better colour balance, still I'm thrilled with the result.

Details are as follows;
Celestron C9.25" XLT SCT @ f/6.3
ATIK 16HR with only UV/IR blocker (no LPR filter)
L = 27 x 1min
R = 15 x 1 min
G = 15 x 1 min
B = 15 x 1 min
The images were combined separately and then turned into an LRGB composite then applied 10 iterations of Lucy-Richardson deconvolution, and a 3x3 rank order filter to supress some green noise in that channel.

Nice image Dave. Colour is a tad off as you say but you have pretty much all other aspects taken care of.

Very good Dave!! Would be interesting to see a monochrome version in a side-by-side.
