IC5146 Cocoon Nebula

I recently posted a picture of this nebula using my Celestron C5 spotter scope. This time I “zoomed in” by using my 11” Celestron C11.

 

The Cocoon Nebula, catalogued as IC 5146, is an emission nebula and star cluster located about 4,000 light years away in the constellation of Cygnus. it has a span of about 15 light years.

 

Like other stellar nurseries, the Cocoon Nebula holds a bright red emission nebula, blue reflection nebula and dark absorption nebula. The latter two are not evident in my picture, probably due to the light filtering profile of the Optolong L-eNhance filter I used. The massive central star which formed about 100,000 years ago now provides the energu source for much of the emitted and reflected light from this nebula.
