Abridged NGC/IC catalogue

glenc (Glen) · #1 25-11-2006, 03:55 AM

NGC and IC Clusters, Nebulae and Galaxies.

The NGC and IC are large catalogues containing in total 14,000 objects. Most of these (76%) are galaxies. Some are not deep sky objects (DSO). Most of us are not interested in seeing all the faint galaxies. An abridged NGC/IC catalogue is sufficent.

The attached file contains all NGC and IC OC, GC, Neb and PN south of declination +60. It also contains all Gal south of declination +60 that are brighter than magnitude 12. Observers in northern Australia should be able to see to declination +60.

The object counts are:
1,195 galaxies (Gal) with magnitude less than or equal to 12
All 629 open clusters (OC)
All 285 nebulae (Neb)
All 126 globular clusters (GC)
All 121 planetary nebulae (PN)
Total 2,356 DSO south of declination +60.
379 of the above DSO are in the LMC and SMC (Magellan Clouds)

The columns are:
Cat Catalog N =NGC, IC, M = Messier
Num Object number
Type OC, GC, Neb, PN, Gal
Sub Type see the reference below
CON Constellation
Bmag, Vmag blue and visual magnitudes
SB surface brightness
Max, Min large and small diameters
10pm Southern season at 10pm (11pm daylight saving time)
RA 2k Right Ascension (2000) in h m s
declin declination in d m s

The tab-delimited file below can be copied into MS Excel and a filter can be used to select the objects you want to see.
Use data filter autofilter to do this.

What a great resource, Glenc! That will be a huge help to me in preparing my observing list for next year.

I have previously printed off the entire NGC and IC and placed them in a plastic sleeve folder. I consult the lists from time to time to find objects that are less common, ones that most casual observers would never see or even know about. But the fact is, many of the objects are too faint to be practicably observed in backyard conditions. An abridged version that limits magnitudes and is geared to southern observers is well overdue.

Thanks, mate!

How many NGC and IC objects are there in the whole sky?

663 Open Clusters
126 Globular Clusters
303 Nebulae
132 Planetary Nebulae
10,613 Galaxies (3,297 are brighter than mag 13)
50 Objects in other galaxies (eg in M33)

Thats a great site glen .. were you involved in some of the research ?
I thought I bumped a thank you aimed your way somewhere round
the net from O/S.

glenc (Glen) · #5 26-11-2006, 04:11 PM

I helped with these sites.

It's now saved as an EXCEL file in My Documents, Glenn. Bloody fantastic mate!!
Thank-you

spacezebra (Petra) · #7 26-11-2006, 05:45 PM

Thankyou so much - this is an excellent resource.

Cheers Petra

gaa_ian (Ian) · #8 26-11-2006, 07:57 PM

Thanks GlenC, I have just saved, sorted & printed my Summer observing list.
Sorted by constellation, Vis Mag & Type.

allan gould · #9 26-11-2006, 10:10 PM

Most excellent. I will couple this with my set of real sky CDs to plan my imaging in the comming months. Thanks again for a great resource

Arguably the best guide for southern deep sky observers is:
ASTRONOMICAL OBJECTS FOR SOUTHERN TELESCOPES
by E J HARTUNG 1968, reprinted 1984
It contains 467 DSO south of declination +50

The object counts are:
Gal 139, GC 104, OC 92, PN 86, Neb 41, Dark 3, Ast 1, MW 1
Total 467

The file below contains 455 Hartung objects from the Abridged NGC/IC file plus 12 additional Hartung objects marked with a +.

You can copy this tab-delimited file to MS Excel and sort and filter it.
See the explanation for the Abridged NGC/IC below.

There is a book review of the latest edition of Hartung at:

Burnham's Celestial Handbook:
An Observer's Guide to the Universe Beyond the Solar System
(Volume 1) (Paperback)
by Robert Burnham Jr.

The attached file lists the NGC/IC objects in Burnham Vol 1.
I will add Vol 2 and 3 later.

It is based on:
Wolfgang Steinicke's NGC/IC Database Files
http://www.ngcic.org/steinicke/default.htm

Burnham's Celestial Handbook sure is a great read glen

Very sad to read how the author bowed out of life

glenc (Glen) · #13 02-12-2006, 10:13 AM

Yes, Burnham's last days are a sad story.

I found a list of Burnham's objects online here:
http://www.ilangainc.com/ASTROPLANNER/burnham.html

Also a list of objects in Sky Atlas 2000 on the same site:
http://www.ilangainc.com/ASTROPLANNER/SA2K.html

and The Night Sky Observer's Guide too:
http://www.ilangainc.com/ASTROPLANNER/NSOG.html

Terry B · #14 02-12-2006, 11:03 AM

Nice lists Glen.

Thanks

Thanks for the lists, they will be very helpful when the clouds lift

Thanks, mate!

I often joke at our observing sessions that Glen is a walking Arvo Narvis with
servo-cat built in.

regards,CS

It seems that Bob Erdman copied his "Historically Corrected NGC" from Wolfgang Steinicke.

Wolfgang says "The latest versions (2007) of my Revised NGC/IC, Historic NGC, and the biographical data about the NGC/IC Observers will be found only here - and not on the website of the NGC/IC project! Particularly the "Historically Corrected NGC" (HCNGC, Bob Erdmann), presented there, is a mere copy of an older version of my "Historic NGC" (without giving a proper acknowledgment)."

Thank you glenc for the links. I am using Hartung (your txt file, don't yet own the book). I am also using Burnhams Volume 1. Where can I get the next 2 volumes of Burnhams in the same file format?

Also can someone explain the difference between BMag, VMag and SB, please.

I'm assuming VMag is the visual magnitude?

glenc (Glen) · #20 07-07-2007, 09:05 AM

"Also can someone explain the difference between BMag, VMag and SB, please."
Yes V is visual mag, B is the mag on blue sensitive photographic plates and SB is surface brightness which depends on both mag and area.
