Description

IC5117 is one of those PNs listed in various catalogs as "stellar". Some are and some aren't, as I discovered from myself. This actually is one of such, member of perhaps half a dozen (in the combined NGC and IC catalogs north of the equator) of PNs I was unable to resolve (and not for lack of trying). Which doesn't mean they can't but I suspect they are really tough nuts to crack with average amateur instrumentation. Be as it may, there were (and probably there still are) precious few full colour images of these PNs out there.

The PN in question is easy to detect as it is the only green star in the field. Others are not that easy (unless you own a spectroscope, that is).
