Techno Stuff: 5/13/07 ATK-16hr, Megrez 80mm APO at F/6, mounted on LX90 8" SCT, IR 40 minutes total with 8 min subs binning 1x1, RGB 15 minutes total each with 5 min. subs binning 2x2, Autoguided with Atik-2HS and Guidedog from LX90, Darks Applied, CCDStack, Photoshop CS2.
Notes: The IR (Infared/UV blocking filter) frames turned out very well. However, the RGB (red, green, blue filtered) frames suffered from heavy light pollution gradients which CCDStack took care of surprisingly well allowing me to come up with a decent final image. I like doing LRGB processing and plan on doing more with fairly bright objects like M104.
