Description

this is a rather faint nebulosity a little west of Gamma Cas, the star called Navi (but should read Ivan, a joke by astronaut Gus Grissom that became a standard name, as you can read in the "Annals" ). I spotted it at one of my widefields with 85mm, which has not got processed so far - but I noted that tiny smudge might be something interesting.

It's a HII region embedded in a dust lane of the milky way dubbed LDN1317, at a distance of 4700 lightyears. One of these little stallar factories, it contains a star cluster visible only in IR.
