Astronomical Catalogs

Messier and Herschel with NGC numbers

I hold Honorary Messier Certificate #404 for observing all 110 objects cataloged, completed in 1978.

I began logging observations of the Herschel 400 objects on 27 February 2000. My official announcement of this undertaking was made via e-mail to members of the Denver Astronomical Society on March 13, 2000, in honor of the two hundred nineteenth aniversary of Sir William Herschel's discovery of Georgium Sidus (Uranus). I logged the 400th object on May 19, 2002, and received certificate #246 of the Herschel Club on July 1st, 2002.

This has been an excellent exercise in organization.

Progress:
Messier	110 and holding
Herschel	400 and holding
Other nonstellar Deep-Sky Objects	196 and counting
(excluding Globulars/Southern objects)

Guide to the Tables Below

Green NGC numbers are "overlooked objects"

Blue IC numbers are Index Catalog objects

Yellow NGC numbers are Herschel II objects

Light Blue numbers are also Southern objects

Names are from the Observer's Handbook, "overlooked", or common sources

RED Names are my own

Many catalogs of nonstellar astronomical objects will often overlap. If you look at Addendum G: Globular Clusters, you will see that in almost all cases, an NGC globular may have another designation. This may be somewhat exaggerated by the inclusion of the Herschel numbers for many NGC objects, but the idea is still valid.

I use Tirion's Sky Atlas 2000.0 1st ed. Besides a good sampling of NGC objects, it also lists the entire 21 clusters of the Harvard University catalog of star clusters.

There are no orders of precedence that I know of, and in fact for scientific applications, I'm not sure there would be a need for any. However, my web page already has a few overlapping objects (see Mel 15). I haven't exhaustively searched, but I suspect the Collinder and Lund catalogs are more comprehensive works (like Melotte's), and many of the smaller catalogs tend to be subsets of them or others. My precedence list (for Addendum A) is:

Harvard | Stock | Biurakan | Dolidze | Basel
King
Trumpler | Markarian | Berkeley | Czernik
Melotte | Ruprecht
Collinder
Lund

Names:

On all of my Astronomical Catalogs web pages (directory above), I have attempted to gather up all of the given names that I can find for objects on my lists.

This list along with this explanation, bears my first two publicized names for a celestial object. So far, the only other time I have done this was with Messier 27 which I dubbed the Apple Core Nebula. Note that I don't show this in red for several reasons.

Since that time, I have come across another reference to this name for this object. Apart from a few friends I may have told this to, I have never publicized my nickname for the Dumbell Nebula, nor do I have any way to establish if I was even the first to refer to it. History honors the published. Finally, I don't think additional names should be given to prominent objects. It leads to confusion, and in the case of my Apple Core Nebula, it does not respect the beauty and elegance of that planetary nebula. It certainly is not befitting a Messier object.

The Right Eye above is named for the galaxy on the right (east in the star diagonal of my 12" SCT) side of NGC 3395 on the Herschel 400 list. There are two galaxies in Virgo (NGC 4435,38) that have been given the name The Eyes, per Barry F. Madore in the Observer's Handbook.

Having now seen The Eyes for myself, I was far more struck by the appearance of NGC 3395,6 in my 12" SCT as a pair of eyes than I was with the named "pair". Being a fan of double/multiple intendre, I have given NGC 3396 in Leo Minor the name, The Right Eye.
