PK164+31.1 Planetary Nebula

©2006 Richard Murray

Techno Stuff: 4/10/07 ATK-16hr, Megrez 80mm APO at F/6 mounted on LX90 8" SCT, Ha Filter 6nm, 45 mins total exposure with 1x10mins, 1x15mins, 1x20mins, Binning 2x2, manually guided from LX90 with ATK-2HS, no darks, Photoshop CS2, Image Analyzer, Silkypix

Notes:Also known as the Headphones Nebula, this is a very faint, 14.0 mag, planetary nebula located in the Lynx constellation. The image was taken at a low altitude with low level fog and in the direction of the most heavy light pollution at my site. The Astronomik 6nm Ha filters ability to cut through these obstructions is the only reason this faint object registered on the CCD at all! :>))
