NGC 6857 is an emission nebula that looks like a planetary nebula. You can
read all about by filling in Astrophysical Journal volume 157, page L41 on
the form at:
http://adsabs.harvard.edu/article_service.html
This is a 1969 paper. The abstract, first, and last paragraphs should be
enough to get the idea.
My notes call it a faint, round disc, with a diffuse edge surrounding a
central star, which sure reads like a description for a planetary nebula.
