IC 1318 – The Butterfly Nebula in Cygnus
One of my favorite summer targets finally getting some attention. IC 1318 is the sprawling emission complex surrounding Sadr in the heart of Cygnus, with two prominent "wings" of Hα separated by a dark dust lane.

Processing (PixInsight): WBPP, SPCC, BlurX, GraXpert as opposed to DBE for this one), NoiseX, GHS stretch, StarX, color work on starless, recombined with screen blend.
GraXpert really earned its keep on this one, DBE struggled to find true background samples in such a nebula-dense field.
