1. Historic data

Biographical information on 172 NGC/IC observers with 528 pictures (January 27, 2010)

Historic NGC with complete information about discoverers, instruments and references for each object (March 11, 2010)

Historic IC with complete information about discoverers, instruments and references for each object (March 11, 2010)

2. Modern data

Revised New General Catalogue and Index Catalogue

Version: March 11, 2010

The Revised New General Catalogue and Index Catalogue contains and describes all objects of the original NGC/IC compiled by Dreyer. In addition many new objects (named with extension letters) or companions are included, so the catalogues list 14002 entries. All known data, cross identifications and individual names are presented. The problem of existence, quality of the data and of double or multiple entries is discussed. For all objects, except some open clusters and nebulae, precise positions are given. Around 12600 positions were determined using the Digital Sky Survey and RealSky, also many magnitudes, sizes and position angles, so a great amount of the presented data is new. The equinox is 2000.0.

Steps towards the "Revised NGC/IC"

1970 Dealing more intense 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 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).
2010

Latest version of my "Revised New General and Index Catalogue"

  • 14002 entries (original data: 13226)
  • around 12600 measured positions (accuracy 1-2") using the 102 CD-ROM version of DSS
  • galaxy magnitudes revised and column "B-V" added
  • 39096 cross-identifications from 82 catalogues
  • 316 objects "not found" (2.4%)
  • showing the "real" Sky to a great extent
  • status for identical objects based on discovery date, published in the "Historic NGC"
