NGC5371 is a small spiral in eastern edge of the constellation of Canes Venatici.
The galaxy has a size of about 4 arc minutes and a brightness of about 11.4th magnitude, and this image shows you dimmed arms.
You can detect compact five galaxies about 30 arc minutes southwest from NGC5371.
They are members of a small scaled galactic group of Hickson's compact group 68,
rather larger three from A to C have sizes of about 3 arc minutes or so and visual brightnesses of about 11th magnitude.
