Eta Carina - LRGB
I was following almost step-by-step of processing LRGB images from the Starizona - Guide to ccd imaging, and happily managed to extract some good data from my previous Eta Carina RGB data sets.Combined with the Luminance data, I used R(3 min), G(3 min), B(3 min).
The combined method is Median for RGB and Sigma Clip for Luminance. The SNR seems better.
