This small planetary nebula, also known as PK 131-5.1, is located in the constellation of Perseus at a declination of +56 degrees. This magnitude 15 PN spans 30 arc-seconds in our apparent view. I could not find a distance for this object.
The HII and OIII signals are similar, although as with most PN, the HII dominates the rim and the OIII dominates the inner section. The object is almost perfectly circular. The OIII signal shows an oval nature, extending from upper left to lower right.
In total, 3 PN were discovered by the German-born American astrophysicist Erika Böhm-Vitense and published in the 1956 paper, "Extragalactic Nebulae Close to the Galactic Plane". I have now imaged all 3 of them. The other 2 are each more interesting than this one and are found here:
