Description

Sharpless 2-132 is a very faint emission type nebula on the Cepheus/Lacerta border. It lies at a degree southeast of Epsilon Cep, and has a size of about 40 arc minutes.

It is estimated to be about 10,000 to 12,000 light years away... but this is no more than an estimate. It's a well studied region as well, with lots going on as you can see in the image.

It can be glimpsed visually, but that takes a rich-field refractor and very dark skies.

Description: Added a bit more contrast and balanced some of the blue out of the background. I was originally trying not to push the contrast too hard cause I wanted to not damage the fainter nebulosity. I like this much better, though.
