Re: [ATM] Secondary Cage Sizing?

["MATTHEW SIMMONS" <msimmonsmcse@msn.com>]

Wow, I go away to watch a Mariners game and the debate rages on without me! 
Ya gotta love email lists! I am going to use the scope for visual use 
primarily. Maybe I'll fool with some webcam when I build an EQ platform for 
it (this winters project). Just some facts on what I have so far; the mirror 
is a Discovery soda lime, 1.5" thick. The secondary is 2.6." I have never 
tested the optics, but some very experienced persons in my club star tested 
it after I got it and said I had one of the best Discovery mirrors they had 
ever seen and that I should keep my hands on it.

I plan on building the system around a paracorr to take care of the obvious 
coma at low powers. I currently own a 13mm and 20mm Nagler, and plan to add 
a 26mm Nagler for my low power observing. I think I will go with about a 
14.125" ID on the upper cage and not worry about the vingetting.
