Planetary nebulae

Notizen: This is Pk131-5.1 in Perseus. My picture doesn't show the beautiful inner structure that is visible in the digital sky survey. Rings around bright stars are courtesy of the UHC filter. Taken from the middle of Berlin with an 8" LX200 at f/6.3, MX716 camera, video autoguider, UHC filter for 11x5 minutes.
