| INSPIRED BY THE MESSIER CATALOG, here is a new list of 109 deep-sky delights to challenge | |||||||
| amateur astronomers, as described in Sky & Telescope's December 1995 issue, pages 38-43. | |||||||
| (This online version is revised and updated relative to the one that appeared in the | |||||||
| magazine.) | |||||||
| The Caldwell Catalog is presented in order of descending declination (all positions | |||||||
| are equinox 2000.0). For an observer at latitude X° N, all C objects at declinations | |||||||
| north of (X-90)° will rise above the horizon at some time of year. Thus, for example, | |||||||
| an observer in Boston (42.3° N) has a shot at C1 through C80, but C81 through C109 are | |||||||
| too far south. For planetary nebulae a size of, e.g., 0.3/2.2 means that the bright | |||||||
| nucleus is 0.3' across while the faint outer shell spans 2.2'. For more information, | |||||||
| see the companion article, The Origin of the Caldwell Catalog. | |||||||
