# NGC Catalog subset # FIXME: Need to convert this into a dictionary such that we can more efficiently obtain # the astronomical data (including common name) when looking up the catalog # number. # # Key to Type representation: # SNR = supernova remnant # GCl = globular cluster # OCl = open cluster # C/N = cluster and nebula # PlN = planetary nebula # Gal = Galaxy # Dbl = double star # DfN = Diffuse Nebula # ??? = unknown or unclassified object # # Note: Objects smaller than 10' or dimmer than magnitude 9.0 have been removed from this # catalog, as they are not going to be visible even in good binoculars. Objects which # duplicate entries in the Messier catalog have also been removed. # # Most of these objects come from the Bennett list of southern sky objects which are not # comets.
