Messier M27 - The Dumbbell Nebula. Shot using a Meade LX200 10" @ f/7.15 and SBIG ST-2000XM with SBIG AO7. 40 minutes (4 x 10 minutes) luminance at 1x1 binned. Luminance frames shot on 10/9/06. RGB (1 exposure x 5 minutes) for each channel. RGB frames shot on 10/21/06. Image scale is .85 arcseconds per pixel. Acquired using CCDOps. Dark frames applied. Self guided by SBIG AO7. Still tweaking everything. This image is especially pleasing. Look how sharp the dim stars look! A mostly full moon was 1/2 sky away. The original luminance was purely test session of the latest adjustments to my pier and PEC.
