Another Sharpless2 object that is seen in the context of the surrounding H-alpha clouds thanks to the CMOS chip and stretching optimized with GHS.
She 179 is the one on the left and better seen in the close in image below. I am going to run some O-III on 180, but no astrobin images has found any after a couple attempts. [Ran 2h on Nov 17 2022 and no signal at all in O-III]

Sh2 180 Faint Sharpless2 Object From GalaxyMap:Sh2 179: This is the planetary nebula PN BV 5-2 (sometimes designated PN BV-2).
Sh 2-180 is visible in the direction of the Perseus arm
Cas OB7 association, but a distance estimate based on CO velocity places it much further away in the Norma/Outer arm.
Avedisova also locates it at a large distance and concludes that it is ionised by the O7.5V star
LS I +62 139.
The filaments visible in this image, more characteristic of a close supernova remnant than a distant HII region, suggests that this region may deserve deeper investigation.
