The Interactive NGC Catalog Online
This is the interactive NGC (and IC, and Messier) catalog at
SEDS, based on the famous
NGC 2000.0 by R.W. Sinnott of Sky Publishing Corp., who also created the
electronic version used by this online service (thanks to
Sky Publishing for permitting us this
kind of use).
Only some minor corrections have been included
in our online database.
The HTML interface and its features were created by
Hartmut Frommert.
Thanks to Bill Arnett
for helpful hints and support, and the admins of
SEDS who provided the appropriate
hardware and software basis for this service.
Thanks to Bernard Trézéguet, this service is now available in
French language also.
The NGC and its supplements IC I and IC II were originally compiled by
J.L.E. Dreyer and published 1887 (NGC), 1895 (IC I) and 1908 (IC II).
It contains open and globular star clusters (and some asterisms), diffuse
and planetary nebulae, supernova remnants, galaxies of all types (and some
knots in bright galaxies), and some erroneous entries corresponding to
single or double stars, or no objects at all.
You will get the NGC 2000.0 data for each NGC, IC, or Messier object,
including J.L.E. Dreyer's description code. Moreover,
for most of the objects, cross identifications
are given for some (mostly older) catalogs, including John Herschel's GC
of 1864 (with Dreyer's later extension), John Herschel's 1833 and 1847
catalogs ("h"), William Herschel's catalog published between 1786 and 1802
("H"), Lacaille's catalog of 1755 ("Lac") and James Dunlop's catalog of
1828 ("Dun"), as well as the sources and references given in Dreyer's
original catalog, and some collected remarks.
In addition, you get a link for downloading an image from the
Digital Sky Survey
for each object, as well as a link to the data of the
Wolfgang Steinicke's
Revised NGC and IC Catalog, a link to the data of the
NGC/IC Project, a link to the data of
NASA/IPAC Extragalactic Database
(NED), a link to the data of the
SIMBAD Astronomical Database,
a link to the
Hubble Space Telescope (HST) Archive images for each object,
a link to the publication references at the
NASA Astrophysics Data System (ADS),
and a link to the observing reports collected at the
IAAC NetAstroCatalog.
If available, you will also get a link to some descriptive HTML page,
and an image of the object. Most of the images and descriptive pages are from
the SEDS server, but some external links are
included, notably from Digital Images of
the Sky by Till Credner and Sven Kohle, the
Advanced Observing Program (AOP)
of the Kitt Peak Visitor Center, the
Anglo-Australian Observatory (AAO), and the
National Optical Astronomy Observatories
(NOAO).
Please type in the NGC number (either as number only, or preceded by 'NGC'
or 'N'), or the IC number preceded by 'IC' or 'I', or the Messier number
preceded by 'M', of the object you'd like to find.
Some browsers (e.g., Lynx) require that you hit a key ('s' or 'S' for Lynx)
to activate the input line.
Note: (as of February 2002; still necessary in 2012)
Some versions of some browsers are unable to handle our interface correctly.
In this case, use the following entry, and then the input line
there for your inquiry: NGC 1.
Statistics:
As of the counting of July 2007, we have the following statistics for the
Messier, NGC, and IC catalog:
Type M NGC IC NGC+IC+M
Galaxy 40 6029 3971 10000
DN/SNR 7 144 97 241
PN 4 94 36 130
OC 28 685 38 724(*)
GC 29 114 8 122
Pt.Gal 0 27 23 50
Dup 0 255 338 593
Stellar 2 395 651 1047(*)
NF 0 97 224 321
Total 110 7840 5386 13228(*)
Type Key:
Galaxy: Galaxy;
DN/SNR: Diffuse Nebula or
Supernova Remnant;
PN: Planetary Nebula;
OC: Open Cluster
(including Milky Way star cloud);
GC: Globular Cluster;
Pt.Gal: Part of Galaxy;
Dup: Duplication (in IC, may be from NGC);
NF: Not found.
Remark: (*) Including non-NGC/IC Messier Object
(OC: M45, Stellar: M40).
Most Messier objects are also contained in either NGC or IC catalog.
Of the globular clusters, 104 NGC and 3 IC objects belong to the
Milky Way galaxy,
8 NGC and 5 IC objects to the
Large Magellanic
Cloud (LMC), and one NGC object each to the
Small Magellanic
Cloud (SMC, NGC 292) and the
Fornax Dwarf galaxy;
see a summary list; this count is based on
Wolfgang Steinicke's
revngc/revic.
NGC and IC only contain entries for 6 supernova remnants (SNRs), 4 in the
Milky Way galaxy and two in LMC: The Crab Nebula
(NGC 1952,
M1),
the Veil Nebula
(parts of it cataloged as NGC 6960,
6974, 6979,
6992, 6995
and IC 1340),
NGC 2736 as part of the Vela Supernova Remnant,
and IC 443 in Milky Way, as well as
NGC 1918 and
NGC 2060 in LMC.
Note: NGC 2000.0 has one object classified as
"Photographic Plate Defect;" that is IC 3601.
It is actually a galaxy though.
