[Utah-astronomy] Central Stars in Planetary Nebula

Hi All, As I recall, we had a discussion on central stars in PN. I remember searching the Helix because someone said the Helix does not have one. I recently searched my old Deep Sky Magazines and found an article from Jack Marlin (Lumicon founder) They have a list of PN with observable central stars, they list the Helix (NGC 7293) as having a 13.47 mag star, spectral class sdO. I will tack the list up at SPOC when I get a chance to photo copy it. Copyrites probably prevent me from posting it on this list. It is from the Summer 1986 issue, it has a rather complete list of summer planetary nebulas for amateurs. Erik
