New Discovery – Sharpless 215 is a potential planetary nebula: Pa 167

Sharpless 215 has, like other objects in the Sharpless Catalog, been classified as an HII emission nebula. My good friend Dana Patchick recently spotted a hot star apparently located within the nebula, and suggested that it could possibly be a planetary nebula. He suggested that I turn my scopes on it, looking for any OIII emission. Although much fainter than the HII emission, I found a strong OIII signal which is characteristic of planetary nebulae. We now await spectroscopic analysis to be able to confirm that it is a PN. Dana has registered it as a possible planetary nebula in his catalog as Pa 167.
