Description

This is an ancient Pn in Cepheus. I first imaged this last October and finally got around to imaging this again in August this year. Then I promptly forgot to process it. This has at least 3 different orientations on the images which has led to severe cropping.

VdB 152 lies very close to this so for people with a larger FoV this offers a great colour contrast with the dark nebula.

Rev B: Re-processed using a different orientation which helped with the stars.
