Test shots 20 x 10 sec for R,G,B with SCT 8" at f/10. It looks like a overgrown star, and after processing it gets greenish:

More aperture and focal length needed. Also DS camera like DSI III Pro doesn't seems to be suitable for imaging small planetary nebulas with high surface brightness. Planetary cameras do better with such imaging... As a comparison picture by Sebastien Caille, and emission spectrum - mainly O-III and H-a. Very low N-II and S-II.
