Planetary nebulae

Notizen: PK 173-5.1 is an extremely faint planetary nebula in Auriga. The object itself is a very faint glow just a bit under the middle of the picture, the bright ring around the brightest star is an artifact caused by the UHC filter. Taken from the middle of Berlin, 2*20 minutes with 8"LX200 at f/4 with UHC filter and MX512 camera with STAR2000.
