ASTRONOMICAL ORGANISATIONS

WILLMAN-BELL, astronomical publishing house and home of the Uranometria 2000.0 atlas.

THE WEBB SOCIETY. An international organization of deepsky enthusiasts, head-quartered in England. They produce a number of good deepsky publications, e.g. "The Deep-Sky Observer" and "Observing Section Reports".

NGC / IC PROJECT HOME PAGE Great resource on the grand-daddy of deepsky catalogues, with extensive details on a project to update the NGC and IC compilations.
Do you need to decode "eF, L, smbM"? Find the key on the "Original NGC/IC Catalogue" page.

BERT DEKKER'S PAGE Highly recommended resource for those starting out.

MINIMUM APERTURE CATALOGUE A great archive of deepsky drawings and observations, maintained by Jere, part of his MAC (Minimum Aperture Catalogue). He writes: “The main aim was (and is) to determine the smallest telescope needed for a visual sighting of any deep sky object. The up-to-date version includes almost all objects in Uranometria 2000.0 and many other clusters, nebulosities and galaxies.”
