Planetary Nebulae in Milky Way Globular Clusters
Up to now, the following planetary nebulae have been reported in
Milky Way Globular Clusters:

A former candidate was Peterson 1 (Pt 1; PK 004+03.1, see
Peterson 1977), an object in the
neighborhood and perhaps associated with globular cluster NGC 6401
(RA: 17:38.6, Dec: -23:55 for 2000.0) in Ophiuchus.
However, Acker and Stenholm (1990)
found that this object exhibits a red stellar continuum - thus is not a
planetary nebula but a symbiotic star.
