This is a small-scaled bared galaxy of NGC5248 floating around south west of Bootes near the boundary on Virgo. The galaxy has a long axis of 6 arc minutes and an apparent brightness of 10th magnitude. This picture shows you two undeveloped arms are stretching in east west direction. But the galaxy shows you a simple lump of dimmed light through large-scaled telescopes. And it's considered that NGC5248 is a member galaxy of the Virgo Cluster though it's lying considerably distant field.
