IC 5146, the Cocoon Nebula (August 2018)

This target in the constellation Cygnus carries emission signal, but it not strong.  What you see here is the H-alpha emission.  In full spectrum images, though, much of the nebular glow is reflection.  The bright star in the middle is a young, B-type star that powers the nebula.  It is surrounded by young stars forming from the disrupted dust and gas in this region.

This image is 9x1800" with the SXVF-H9 through the Synta-ONTC8 f/4.95 reflector.
