Important note: The "Historically Corrected New General Catalogue" (HCNGC), first presented in April 2006 by the former NGC/IC Project webmaster Bob Erdmann on the project website, is a mere copy of my Historic NGC of 2006 - including all its errors and uncorrected data.It is sad, that the necessary acknowledgment for using my data is not given there!The illegally presented "HCNGC" is incorrect and completely outdated and thus should not be used in any serious query!Hopefully it will be removed from the NGC/IC website and replaced by my "Historic NGC/IC".
The contains and describes all objects from the original NGC/IC, compiled by Dreyer. Additionally, many new objects (named with extension letters) or companions are included, so the catalogues list alltogether 13958 entries. All known data, cross-identifications and individual names are presented. The problems of existence, data quality and double or multiple entries are discussed. For all objects (except some open clusters and nebulae) precise positions are given for 2000.0. Around 12600 positions were determined using theDigital Sky Survey (DSS) andRealSky, also many magnitudes, sizes and position angles, so a great amount of the presented data is new.
