Abell 12 Planetary Nebula in Orion

This quite large planetary nebula hides in the glare of mOrionis (see finder chart below).

 

The above image was taken on January 19, 2002 from Harrowsmith, Ontario. Cookbook 245 LDC camera was used on Celestron Ultima 8 f6.3 SCT autoguided with Cookbook 211 on a piggybacked 500mm f8 telephoto lens. Thirty white exposures (30 sec. each) were combined using AIP4WIN software. Images of brighter stars were partially masked to help visualize this faint planetary nebula.

North is to the left.

Map created in Guide 7.0 - 7°45' x 7°45'. North is up.
