The Brightest Planetary NebulaeObserving AtlasWhite version

2012-5

This atlas is aimed to illustrate the appearance of various planetary nebulae visible insmall telescopes (between 8 and 15 cm of aperture) from suburban locations, providinga description and the related observational, physical and location data. Both theconsidered range of aperture and quality of the sky are common to many amateurobservers, who are forced to deal with a gradual increase in light pollution. However, thesurface brightness of several of these objects is so high that they can be easily observedfrom suburb locations, and in some cases even from city centers. In more isolated areas,with a limit visual magnitude of at least +5, small telescopes are able to show relativelyweak planetary nebulae.Most of the observations have been performed with a good achromatic refractor of 120mm of aperture and 1000 mm of focal length, which in the case of nebulae of smallangular extent can be used profitably at magnifications in the order of 250x.Occasionally, or in the case of older observations, a 127/1250 Schmidt-Cassegraintelescope, a 114/1000 Newtonian, a 102/500 refractor and a 20x80 binoculars havebeen used.The sketches were executed with pencil on white paper, and then scanned andprocessed with an image editor program, with which a slight blur to the nebula has beenusually applied in order to make the look even more realistic.Objects data were taken from ‘The NGC/IC Project’ (http://www.ngcicproject.org/) and‘PNebulae’ (http://www.pnebulae.altervista.org/index.html), while the used star maps arefrom ‘Taki’s 8.5 Magnitude Star Atlas’ (http://www.geocities.jp/toshimi_taki/index.htm).The adopted seeing scale is that of Antoniadi modified (1-excellent, 6-very poor). Theobjects are arranged according to their right ascension.I hope that this collection may be useful for your observations.

Good vision and clear skies,
