M27 - The Dumbbell Nebula (my first 10 minute subs)

Skunk Hollow Observatory

Messier M27. 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. 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. This was purely test session of the latest adjustments I have done to the wedge and a couple of other things.
