The Crescent Nebula (NGC6888) is about 4,700 light years from our solar system and can be found in the constellation of Cygnus. The name derives from its "hump" which appears to the west as the Moon observable in the growing phase. It is an emission nebula that must form (bubble) and brightness to the stellar wind generated by the Wolf-Rayet star inside it.
The lights were taken at the Valle degli Ulivi in Manduria (Taranto-Italy) at the end of August 2022 with a monochrome camera and Optolong narrow band filters at 3nm.
Lights: 75x300s Ha 3nm + 41x300s OIII 3nm
Sky: Bortle 6
Total exposure: 9,6 h
Telescope: Sky-Watcher Quattro 250P + GPU Coma corrector
Camera: QHY 294 Pro Mono
Filters: Optolong Astronomy Filter HO 3nm
Mount: Sky-Watcher AZ-EQ6 GT
