Sh2-261
Sh2-261, Lower's Nebula in Orion
Sh2-261, Lower's Nebula is an emission nebula on the outermost edge of the Milky Way, on the border of the galactic region between the Orion and Perseus arms. It is located in the constellation of Orion and lies at a distance of approximately 3,250 light years from Earth. The object was first discovered in a photo by Harold Lower and his son Charles in 1939.
The image is composed from 72*5 minute exposures taken through an Ha narrowband filter during 2018 & 2019. Camera - ASI1600 @ -20deg C, unity gain; Scope - AA8RC with CCDT67 focal reducer - F5.4.
