Description

This is a large but very faint SNR in Auriga. It appears to be very rarely imaged, and I could only find four images of it on Astrobin.

Even more rarely imaged is the small planetary nebula that I noticed in the bottom middle. This image may be the first disclosing a central Oiii signal in that PN. Aladin and the HASH data base tells me it is PN KN 36. I could not immediately find out what (who) "KN" refers to, maybe someone can tell me.
EDIT: Of course @DanaPatchick knew and you can read his explanation in the comments below.

This is the first data I have collected in 2024, and the first for a month as both clouds and the moon has conspired against me. It was  taken during a very cold (-25°C) night with 40 cm snow on the ground, which unfortunately brightens up the night even without a moon. So my SQM was 20.3, and not the 21.6 I can get on a moonless night without snow on the ground. The next night was also clear but then the temperature fell to -29°C and I decided against opening up the obsy for the well being of both me and the equipment. It was taken with my dual-RASA rig so I could collect a fair amount of data in one night.

Here is a crop of the small PN KN 36. Something for someone to aim at with a longer focal length telescope.
