Caldwell Catalog :
Sr. Patrick Alfred Caldwell Moore (1923 - )

I felt that the Messier Catalog was incomplete. This fact struck me forcibly one evening, not so long ago, while I was out browsing around the sky. I looked casually at NGC7293, the Helix Nebula in Aquarius, and wondered why it did not have a Messier number; it could easily be taken for a large comet. Many of these non-Messier sights are shamefully neglected. Why not draw up a catalog to list objects not identified by Messier? Why not extend that list so that it includes objects below the Paris horizon?... One morning I sat at my desk and began work. I decided to list 109 objects (the same number as in the Messier Catalog) but to arrange them or order of declination... the objects had to be accessible to amateurs using modern 4-inch and larger telescopes under a dark sky... Next, the question of a name, like Messier, to go along with the number system. I could hardly use M (for Moore), because Messier begins with that letter. Fortunately I am officially Patrick Alfred Caldwell Moore...*

I have photographed over 66% of Pat's List from the end of my driveway, and I have updated most of these images from output taken at the observatory in New Mexico. The remaining objects are too low in the horizon for me to image from either the observatory in New Mexico or my driveway in Florida.
