In total there are 109 objects catalogued by Sir Patrick Caldwell Moore, known collectively as the Caldwell Objects or the Caldwell Catalogue. Amongst the 109 objects there are 28 open star clusters, 18 globular star clusters, 13 planetary nebulae, 12 bright nebulae, one dark nebulae, and both halves of a supernova remnant.
Every object within the Caldwell catalogue should be visible with a 4-inch telescope under a dark sky, and most are also visible with binoculars (and in many cases even with the naked eye).
Listed below are a set of Telrad finder guides to the 109 Caldwell objects in Adobe Acrobat format, created using Skymap Pro. Click on a link to download the PDF chart of your choice.
Telrad Finder guides for the Messier Finders are also available, along with a limited number of finder charts for other Misc Deep Sky Finders objects. Each finder guide is centered about the object listed (with an overlaid Telrad sight) and shows surrounding objects down to either magnitude 6.5 or 7 depending on the chart. If the object has a common name this is listed, otherwise the object type is noted.
