NGC7662 - The Blue Snowball in Andromeda

The Blue Snowball - a planetary nebula - in constellation Andormeda is small, you need a larger telescope to see i good. Here I have used CPC 11oo, Focal length 2800, f10 with Canon 40D modified. 19x2 min ISO 800 and 8x4min ISO1600, guided with Celestron 80ED and NexImage videocamera.
