Charles Messier described the Dumbell Nebula in Vulpecula as an "oval nebula without stars", when he came upon it in 1764.
Taken with a Canon 10D digital SLR coupled to an 8" mak-Newt with a 1.25X 2" Denkmeir OCS, this image is comprised of twelve 480 second shots taken at ISO 400 and an ambient temperature of 50 deg F. Processing done in Images Plus, with final touches in Adobe PhotoShop.
The upper image is resized (but uncropped), from the native 3072x2048 to 720x480, and the image to the right is a 400x400 cropping taken directly from it. |
