Description

Sorry for the very complicated title of this image, but it contains both a SNR and a PN and none of them have any better names than these designations.

The Ha-emitting planetary nebula (IPHASX J055226.2+323724) lies in the star cluster M37 and was first reported in 2022 (https://iopscience.iop.org/article/10.3847/2041-8213/ac88c1). I only know about one other image of it since then, and it is by @Sven Eklund  and @Marcel Drechsler (https://www.imagingdeepspace.com/iphasx-j0552262323724.html). It is believed to be the oldest visible planetary nebula. The Ha signal is much stronger than the Oiii.

The supernova remnant (G179.0+2.6) is quite big and therefore old and faint. I only know of three other images of it here on Astrobin. It is quite close to a more famous SNR: the Spaghetti nebula, as can be seen in this wide field image by @Rolf Dietrich  (https://www.astrobin.com/j0p1vg/).

Finally, there is a faint bluish space oddity near the bottom left. It puzzled me first but the Astrobin annotation says it is galaxy PGC 17836, and it seems partly obscured by dark nebulosity from our galaxy.
