- I believe the 4.2-m telescope is in part, or maybe mainly, funded by the Discovery Channel.

wow, had no idea Lowell had a 4.2m. We hardly ever hear anything out of Lowell except sometimes visitors get to use the Clark 24" if they pay enough. I didn't know Lowell had the funding for such a huge scope. -Jason----- Original Message -----From: wilcoxmiltonSent: Thursday, January 08, 2009 1:39 PMSubject: [tec-scopes] Re: Telescope Planetary Ranking - TEC140 does quite well.--- In tec-scopes@yahoogro ups.com, "jmadamik" <jason@...> wrote:

At Lowell, Brian has logged over 3 decades on a 21 inch Classical
Cassegrain making photometric measurements of stars, planets and the
Galilean moons. I'm not surprised that he would use a quality apo for
visual work in the Flagstaff area because of the seeing issues.
Fortunately, the site of Lowell's new 4.2M Telescope is consistently
better (median ~ 0.85").
