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.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
