Chuck, Touche! Still, 60% of a 48-inch mirror aint all that bad... ;-) Actually, most of the NGC was compiled using an 18.8 inch, but then he really didn't need a telrad; most of his observations were done with the scope in a fixed position overhead, where he let objects simply drift into view and would call down the observation data to his sister at the foot of the ladder. Now if I could just convince one of my sisters to stand at the bottom of the ladder... :-) --- Chuck Hards <chuckhards@yahoo.com> wrote:

Actually, while they encourage you to still find objects the same way Herschel did, the A. League's Herschel Certificate requirements do not put any restrictions on using setting circles or goto scopes; (hey, let's face it, he also didn't have the same light pollution challenges we face today
Heh, heh, he also only had a mirror with about 60% reflectivity, terrible local air pollution due to unregulated burning of coal in every house in the country, no Telrad, and inadequate clothing in winter.
We've got things pretty easy, actually.
Thanks Rich, good luck on the certificate!
