Re: ATM Diagonal




I've decided on the biggest diagonal I could use for a 6" f/8, but I 
didn't understand two things:

1. One said that 1.3" is the maximum, and a second said that 1.4" is.
2. I don't know where I should place the diagonal _in_ the "light Cone" 
(my tube diameter is 7" [well, it's not really a tube, because it's an 
alice-like telescope]).

Help me!
