Sadr Region
A colorful area in the center of the constellation Cygnus, showing the Crescent Nebula and open cluster Messier 29. Long exposures reveal a rich starfield otherwise hidden by light pollution, and the filter preferentially passes the red light emitted by vast clouds of hydrogen space dust.
Tech Stuff: Borg 55FL/ZWO ASI 1600MC/IDAS LPS-V4 filter. 42 minutes of 4 second unguided exposures captured as SharpCap livestacks, processed with PixInsight, Topaz AI Denoise; and ACDSee Gemstone 12. From my yard in Westchester County, red zone Bortle 7 sky.
