A planetary nebula in the constellation of Ursa Major.

Exceptionally faint and rarely imaged because it's so faint. Indeed the only previous images I could find were

A very obscure high excitation planetary nebula discovered in 1995 by James Liebert, Richard Tweedy, Ralf Napiwotzki and Michael Fulbright. At its heart is the eclipsing binary star system BE Ursae Majoris.

This is so faint that it's almost invisible on 1800s exposures, so I had to resort to capturing OIII data at bin 3x3, and lots!
There is a tiny amount of Ha, but even 1800s at bin 4x4 it was too faint to use.

Many thanks to Sakib Rasool for suggesting this target to me.
