M27 - The Dumbbell Nebula

< Previous Next >Inspired by the M57 image from previous night I decided to try if my camera can capture a bit fainter object M27. Its surface is about 2 magnitudes fainter than M57's. After stacking 53 frames some details became to stand out from the noise. I think this is a bit too dim for 15" exposure. I had also some tracking problems (due to inaccurate polar alignment) and the images had differing coma in relation to each other. Processing as in M57, but without deconvolution. Selective Gaussian blur was applied in GIMP.
