ASTRO: Quick and dirty M31 LRGB
i shot some unfiltered lumnance last night of M31: 3.75 hours. I added that
to the color image (6 hours) taken last week to make an LRGB this was a quick and dirty processing of the data using some old version of photshop on my laptop. I am curious to see how this will look when I can get back to my regular computer for processing it. Using the PL39000C one shot color in conjunction with the PL16803 for luminance seems like a good way to go. The scope was an AP%%EDF f/7 with the 4" field flattener The Luminance was shot last night with about 83% of the lunar disk illuminated. The skies were reasaonably transparent it seems. |

That laptop monitor must be dying. The image is way too bright on mine losing a lot of detail and color. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct.

All your other images appear correct to me, just this one seems blown out. I usually set my background to about a count of 15 or so out of 256. I do like it rather dark rather than gray. This new monitor does show the darker levels better but using a 24 step gray scale each level is virtually an identical increase in brightness.
