It sits on a line between the mag. 9 star involved. It sits 17' south of the star Chi Ursae Majoris, just south of the bowl of the Dipper. Increasing aperture helps brighten the middle, as well as produce a mottled appearance. NGC3893 makes a good jumping off point for three small faint galaxies.
Many stars lie to the west.
Dreyer optimistically describes it as very bright. Countless galaxies fainter than mag. 15 inhabit this image. 14.1 and covers 1.8'x0.5'. It's small size compensates a little for its dimness.
