Re: [ATM] 1.25in Versus 2inch focuser.

["Jerry" <wa4guu@verizon.net>]

"IF" a 1.25" were large enough for your purpose, a 2" would still be a wise
choice. You could then place a baffle at the bottom edge of the drawtube and
reduce reflection off the inside of the drawtube.  Besides that, almost for
sure, at some point in time you will have a fine 2" diameter eyepiece in
your hand that you wish you could put in your scope.

Which should I consider for the following scope:

20in F5 mirror. 


My question is, what advantage would I get from fitting a 2in focuser if
the 1.25inch eyepiece gives me my maximum practical field of view.?

For that matter, is there any point in fitting a 2in focuser to anything F5 
or faster?

any illuminating ideas?!!

Marco.
