NGC 3310 is a grand design spiral galaxy in the constellation Ursa Major. It is a starburst galaxy and it is likely that NGC 3310 collided with one of its satellite galaxies about 100 million years ago, triggering widespread star formation. It is thought to be located approximately 46 million light-years away from the Earth, and is thought to be about 22,000 light-years wide.The ring clusters of NGC 3310 have been undergoing starburst activity for at least the last 40 million years.Two supernovae have been discovered in NGC 3310. SN 1991N was spotted March 29, 1991 at an offset of 5? east and 7? south of the galactic nucleus.  A second supernova, SN 2021gmj (mag.15.1, type II) was discovered March 2021.

The dynamic range of NGC3310 and the glare of fifth magnitude star HD 92095 add to the challenge.
