This is a recent 7.5 hour LRGB of M66 taken from my NM observatory to replace old 2002 data from my local, California area. I think it came out pretty well even though it was a "quickie" in terms of luminance data and processing. Used a 20" RCOS RC on a Paramount ME. The camera was an STL-11000 with the AO-L unit and SBIG CS filters. Randy Nulman
