Description:

NGC 3877 is a tiny (4'.4x0'.8 in apparent size) jewel of a 12.1 apparent magnitude galaxy which, in order to render visible some of its structure, required the integration of 326x300s subs equating to 27.2 hours of total exposure. In 1998 a Type IIn Supernova, SN1998S, was observed within this galaxy. I photographed NGC 3877 (a Type Sc Spiral Galaxy in Ursa Major) on 11, 12, 14-16 and 19-21 March 2023 from a Bortle class 8 area. Having acquired 326x300s subs, which equates to 27.2 hours of total exposure, I processed the data in Pixinsight.
