Important note:
The Historically Corrected New General Catalogue (HCNGC), first presented in April 2006 by the former NGC/IC Project member Bob Erdmann on the project website, is a bold copy of my Historic NGC of January 2006 – including all its errors and uncorrected data. It is sad, that the necessary acknowledgment for using my catalogues is not given there! The version of HCNGC on the NGC/IC project website is incorrect and completely outdated and thus should not be used in any serious query! It is sad that the HCNGC is up to mischief in the internet - especially in american astronomy forums. For the background of this issue look here.
Version: 20 March 2023
The Revised New General Catalogue and Index Catalogue 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 13957 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 the Digital Sky Survey (DSS) and RealSky, also many magnitudes, sizes and position angles, so a great amount of the presented data is new.

Steps towards the "Revised NGC/IC"
| 1970 | Dealing more intensely with deep-sky objects (observing, data). Further biographical informations are here. |
| 1982 | First "Revised IC" (analog) |
| 1984 | "Katalog heller Quasare und BL Lacertae Objekte", "Katalog der Galaxiengruppen" (German versions) |
| 1987 | First version of CAT 2000 (digital) |
| 1997 | First complete "Revised NGC/IC" (based on historical sources, visual observations, DSS, CAT 2000) |
| 1997 | Core team member in the international NGC/IC Project . Other members: Harold Corwin, NASA/IPAC; Malcolm Thomson, Oceanside; Steve Gottlieb, Albany; Brian Skiff, Lowell Observatory; Brent Archinal, USNO (photos are here). |
| 1997 | Continuous updates of the "Revised New General and Index Catalogue" |
