Find the Messier and Caldwell objects in the night sky at your observatory, as well as a few distinctive variable stars and transient events. The NGC and IC catalogs may be searched selectively by entering a specific name below, or by entering a partial name to limit the size of the search. Try something like "NGC 2" which would search everything staring with that from NGC 2 to NGC 2999 since long NGC searches will timeout.
The Caldwell list is from Observing the Caldwell Objects by David Ratledge (Springer, London, 2000).
The Messier list is based on the Wikipedia entry as of March 12, 2017.
The NGC catalog is from NGC 2000.0 by Rinnot (Sky Publishing, Cambridge, MA, 1988) provided through the CDS Viziers service.
The software producing this page is based on Tapir, created by Eric Jensen.
