Planetary nebulae


Notizen: Pk128-4.1 is a BIG planetary nebula in Cassiopeia and as far as I remember the first object I have shot that isn't listed in "The night sky observer's guide". It reminds me a lot of the Medusa nebula in Gemini. The upper version is meant to look nice while the lower version has a stronger logarithmic stretch to better show the extent of the nebula. Taken from the middle of Berlin with an 8" LX200 at f/4, MX512 camera, UHC filter, video autoguider for 6x10 minutes.
