Planetary nebulae

Notizen: Abell 61 (=PK 77+14.1) is a large planetary nebula in Cygnus. It is barely detectable in the digital sky survey, so it is probably quite faint. I'm having a lot of problems with focusing recently so stars are very blurry. Taken from the middle of Berlin with an 8"LX200 at f/4, MX512/STAR2000 camera plus UHC filter for a total of 200 minutes (10x20 minutes).
