NGC 2371 is a little odd in a couple of ways to me.

First, it has two entries in the <a href="http://en.wiki.x.io/wiki/New_General_Catalogue" rel="nofollow">New General Catalogue</a> because astronomers (specifically, William Herschel) <a href="http://stars.astro.illinois.edu/sow/n2371.html" rel="nofollow">thought</a> it was two objects at the time.

Second, for processing, the HLA only has one channel worth of data for the left side which is why it appears dimmer and monochrome in my version. I also processed it slightly differently than I usually do because I liked the look with the f656n filter in the red channel along with the f658n. Usually I like those two to be in separate channels.

Anyway, it's a picturesque nebula. It has a very soft appearance which I quite enjoy. HubbleSite has <a href="http://hubblesite.org/newscenter/archive/releases/2008/13/image/a/" rel="nofollow">a nice article</a> on the nebula if you are interested in learning more about it.
