NGC 3981 is a small spiral galaxy in Crater that's rarely imaged by amateurs. At around 62 million light years away, it is part of the NGC 4038 group, named after one of the pair of galaxies called The Antennae. The central portion is very small and the outer reaches are very faint! The bright central spiral structure is a mere 4 x 1 arc minutes. Its faint extended structures have an apparent size of roughly 8 by 5 arcmin and suggest some kind of interaction with another galaxy long ago.
