M110 is the larger and fainter of two prominent satellite galaxies of M31, which is in the lower left corner of this field. Most elliptical galaxies tend to be relatively featureless, but M110 shows some hints of structure and dust lanes near its core. Visually M110 is relatively faint and diffuse, lying on the opposite side of M31 from the smaller and brighter M32.
M110 along with M31 and M32 are currently well-placed high overhead in the early evening.
