Description

This is a 4-panel mosaic of the H-alpha nebulosity in the constellation Cygnus, but to me it looks a bit like a wind-swept wildfire with embers blowing through the wind. It could have been done in 3 panels, but I'm just not that good at framing.

I used my H-a modded Canon 600D, Rokinon 135mm f/2 with Optolong L-eNhance filter front-mounted with step-down rings, and Skyguider Pro guided with PHD2. I got a total of 170 300-second light frames at ISO 800 across the four nights, with a set of 12 darks for each night, and the same set of 30 flats and dark flats used across all four nights.

Calibrated, stacked, and mosaick-ed in Astro Pixel Processor, star reduction with Starnet++, and recombination and final tweaks in GIMP.

C&C welcome! Thanks for looking.
