IC5146 Cocoon Nebula

Nebula with surrounding dust (dark nebulosity) about 4000 light years away, in the constallation Cygnus. The central illuminating star is very young...only about 100,000 years old. Humans were on Earth when this star was born!

 

This image is a lot of "firsts" for me...First light with the new camera, first time trying LRGB method (versus one-shot-color camera), and first time using PixInsight.
