This image was taken on 2017 January, with the FSQ telescope and the QHY90A CCD. It is the result of a LRGB sequence of (14+10+8+11)x900s, for a total of about 10hr45m of exposition.
Lynds’ Dark Nebula (LDN) 1622 appears against a faint background of glowing hydrogen gas only easily seen in long telescopic exposures of the region. LDN 1622 lies near the plane of our Milky Way Galaxy, close on the sky to Barnard’s Loop, a large cloud surrounding the rich complex of emission nebulae found in the Belt and Sword of Orion. But the obscuring dust of LDN 1622 is thought to be much closer than Orion’s more famous nebulae, perhaps only 500 light-years away. At that distance, this 1 degree wide field of view would span less than 10 light-years. Its foreboding appearance lends this dark expanse a popular name, the Boogeyman Nebula.
