The attached file now includes 80 globular clusters, 31 planetary nebulae and 135 galaxies. I have include planetary nebulae larger than 12" across down to magnitude 11.0. Sizes for PN are in arc-secs not arc-mins. C STR is the magnitude of the central star. PN in bold are the brightest ones. Six PN are north of dec +45.

Planetary nebula are often typized for their appearance, according to the Vorontsov-Velyaminov scheme:
1 Stellar Image
2 Smooth disk (a, brighter toward center; b, uniform brightness; c, traces of a ring structure)
3 Irregular disk (a, very irregular brightness distribution; b, traces of ring structure)
4 Ring structure
5 Irregular form, similar to a diffuse nebula
6 Anomalous form
