Sh2-119 (Clamshell Nebula)

This is a bright emission nebula about 2200 light years away in constellation Cygnus.
It is less imaged than its close neighbors the Northamerica Nebula and the Pelican nebula.
The bright star in the center is 68 Cygni, a star of magnitude 5, which is one of the stars, which power the glow of the nebula and which have blown up a bubble emitting blue radiation of ionized oxygen.
Look at the very dense and dark globules which might eventually become stars and planets. Also a few background galaxies shine through the nebulosity in the foreground.
This is a pretty short broadband exposure, but the power of the RASA reveals a lot anyway.
