Hi, I took this data back in December and forgot about it. I did this in unbinned RGB with no luminance. I usually do globulars in LRGB, and wanted to compare it with one done in RGB. I have to admit I can't see much of a difference between this one and my other globulars. I will probably still lean more towards LRGB, but this experiment makes me wonder if the L adds that much to the image. I am curious what others think/do. I think most people do LRGB, but have seen other images on the web in just RGB. Anyway, thanks for looking and comments and suggestions are welcomed. http://www.azstarman.net/M53.htm Thanks, Bernard -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
