NGC2805 is a medium-scaled spiral galaxy positioned at the head of Ursa Major, about 1.5 degrees northwest of 23 UMa.
The galaxy has a brightness of about 11th magnitude and an apparent diameter of a bit larger than 6 arc minutes.
This image shows the indistinct arms are wound loosely.
And two edge-on galaxies can be detected at about 10 arc minutes northeast of the galaxy, a larger one is NGC2820 and another one is NGC2814.
These galaxies are forming a small galaxy group at about 85 millions light years away.
