tHANKS, aDAM, THAT LINK WAS GREAT. I shall study it in great depth. I have been doing most things right, but your advice on the histograms and on getting a good preview is really helpful. One thing I noticed is when I select color, say of a globuklar cluster, it appeared on the screen as a tiny pink dot that I drew the box around. When I selected mono, the cluster almost filled up the entire screen and looked better. Is it all in those sliders???
