Object Type: Planetary Nebula in Constellation Cepheus
Observing Location: Sudelfeld, Bavaria, Germany
Date: 16. November 2012, 11:50 PM
Observer: Christian Rausch
Telescope: 12inch/F5 Dobson (Hofheim Instruments)

Power: 300x (Nagler 5mm)
Conditions: SQML = 21,45 mag/arcsec*2, seeing good, transparency very good, Temp. +3C, rel. humidity 40%
Media: Chalk pencil on black paper

The night from the 16. to the 17. of November was exceptional here in southern Bavaria. A very good transparency combined with good seeing conditions is very rare in our area. In addition the fog down in the valley damped the artificial lights.

It was a great night!
