This is a repeat of my previous post, but with the addition of LEDA, and the Aladin version of DSS, and also the Online version of the Carnegie Atlas of Galaxies.

Online Catalogs & Atlases of galaxies :
_______________________
The homepage of the NED extragalactic database is ::
http://ned.ipac.caltech.edu/
____________________________
The Hyperleda (LEDA) database of galaxies, is very competitive with NED when it comes to general usefulness as a comprehensive online galaxy catalog containing extensive data on hundreds of thousands of galaxies : :
http://leda.univ-lyon1.fr/search.html
________________________________
The SIMBAD database of galaxies is here ::
http://simbad.u-strasbg.fr/simbad/
______________________________
A critically important source of information for the nearby galaxies (those within 11 Megaparsecs) is the Updated Nearby Galaxy Catalog:
http://heasarc.gsfc.nasa.gov/W3Browse/all/neargalcat.html
and also
http://www.sao.ru/lv/lvgdb/pview.php
___________________________________ _____
A quick reference for reliable NGC/IC object data is The NGC/IC Project:
http://www.ngcicproject.org/
___________________________________ _____
A comprehensive Online Catalog of the distances of various galaxies is The Extragalactic Distance Database by R.B. Tully ::
http://edd.ifa.hawaii.edu/dfirst.php
___________________________________ ______
A very comprehensive source of high quality images for hundreds of the brightest galaxies (together with important and very accurate data) is the Carnegie-Irvine Galaxy Survey ::
http://cgs.obs.carnegiescience.edu/CGS/Home.html
___________________________________ _______
Another absolutely essential online collection of images of the members of the bright galaxy population is the Online version of the de Vaucouleurs Atlas of Galaxies:
http://bama.ua.edu/~rbuta/devatlas/imagedatabase.html (http://bama.ua.edu/%7Erbuta/devatlas/imagedatabase.html)

The Carnegie Atlas of Galaxies was the best and most comprehensive collection of "pre-CCD era" galaxy photographs. Many of these galaxy images are still competitive with CCD images. Excellent quality reproductions of these galaxy images, together with expert commentary by the great galaxy classifier Alan Sandage, can be found at :
http://new.astronote.org/bbs/board.php?bo_table=messier
[ Just click on the appropriate NGC or IC range, to find an image and also commentary about the galaxy that you are interested in. ]

The quickest and the most efficient (and often the best quality) version of the Digitized Sky Survey(s) that were done with the big Schmidt Cameras, is Aladin Preview. You have a choice of various wavelengths and various Schmidt surveys and of various scans of the plates, and it is very quick and easy to call up an image of the object of interest. The available option of displaying a color-composite DSS image of an object is not at all colour accurate, but the co-added color image is often more contrasty and sharp : :

There are also gigantic numbers of specialized catalogs and atlases of galaxies......so if you do need to know about them, just ask the Very Bad Galaxy Man! Also, I can "de-jargonize" and interpret the column headings, which often utilize some weird symbols.
Cheers,
Robert
