Mystery Planetary Nebula

Mystery Planetary Nebula
I took the following image on February 10, 2011, from the LAs observatory, in Curby, Indiana. Unfortunately, for some reason, I didn't document this image, so I have no idea what planetary nebula it is. I'm postng a copy of this on the club web site to see if any other members know which one it is. I'm pretty sure it is a circumpolar object. In the mean time, I thought I'd post it here because, well, I think it's kinda neat.

Here is a cropped version so you can see it better:

Enjoy

RE: Mystery Planetary Nebula
Found it. It's the eskimo nebula (NGC 2392).

The Eskimo is a classic planetary nebula, particularly for larger scopes. Discovered by William Herschel in 1787, the Eskimo is 10th magnitude, with a 10.5 magnitude central star. Relatively small, the nebula subtends a mere 20". It lies some 3700 light years distant. The object is located in Gemini, which blows my recollection that it was a circumpolar object right out of the water. Oops. At least I figured it out.
