Planetary nebulae

Notizen: I have never "seriously" imaged M57, so it was about time. This is a 2x enlargement with maximum entropy deconvolution applied. I tried not to make the sharpening look too harsh. Taken from the middle of Berlin with an 8" LX200 at f/6.3, MX716 camera, video autoguider, UHC filter for 51x60 seconds.
