The Butterfly Nebula (IC 1318) in powerful SHO

The Butterfly Nebula (IC 1318) in the constellation of Cygnus is one of the most popular objects in the summer sky. Surrounding the supergiant star Sadr (Gamma Cygni), there is a variety of gas and dark nebulae that make this area incredibly fascinating! I had heard that there is a relatively high amount of SII emission in this region, and indeed, that turned out to be true. I captured a total of 9.5 hours of exposure at f/2, to create this SHO version.
