Part of the Veil Nebula supernova remnant in the constellation of Cygnus. This is also my first finished test image with Optolong’s new L-Extreme filter for fast systems. I was pleasantly surprised at the lack of star halos that are often a problem with narrowband filters, especially at an F/2 focal ratio.
