You're right, Ted.? In fact, if one goes to the "Caldwell Club" page on the Astonomical League Web site (), they show this letter from Sir Patrick himself.

A Letter from Sir Patrick Moore

SIR PATRICK MOORE CBE DSc (Hon) FRAS

Farthings
West Street
Selsey
England

The idea of the Caldwell Catalogue came to me one night, after I had been observing the Moon (my own subject) and had looked casually at the Perseus Sword-Handle. This has no Messier number. (Messier catalogued nebulae as 'objects to avoid' during his comet searches, and in any case limited himself to the northern part of the sky.) There are many Messier clubs. Why not draw up a catalogue of bright nebular objects omitted by Messier?

I did so - and more or less on the spur of the moment, sent it off to Sky and Telescope. To my surprise it caught on, and by now everyone seems to use the Caldwell numbers. I could not use M numbers, because Messier and Moore begin with M - but my proper name is hyphenated (Caldwell-Moore), so I used C.

All the Caldwell objects are within range of modest equipment. They are arranged in declinations, so that to survey them all means some travel - but that is not a problem nowadays.

Why not try a Caldwell competition? This is not a difficult matter - and here is the list; try it and see how many of the C objects you can locate. I wonder who will be the first observer to win a Caldwell Certificate?

I wish you luck, and clear skies!

PATRICK MOORE

BTW, Caldwell Club certificate number 1 was appropriately awarded to Sir Patrick Moore.

I don't think he was "Chosen." I think he sent this list, unsolicited, to Sky & Telescope as a bit of a lark.? He was as surprised as anyone that it even got printed, and more surprised than most that it caught on.
