Re: [ATM] RC Multiple primaries and a single seconday

Hi Julio,,

Im not goimg to try and answere,,because Im not "cassegrain" person,,
but the question is interresting!!,
so Im going to "toss-in" my"probably-wrong" 2-cents,,

just a wild-guesse,,
but the only way for that to work,,form my little knowledge of "Cass-systems",
would be for,,
Instead of using the "same-secondary",,
Why-not use the total "final-focas" from all-3-scopes, to converge at a 
"Deflected-point", of the "combined focus", of all 3-scopes.
BETTER EXAMPLE;
using a "binocular-scope" to "Focas" at a "Monocular Final-focus"!!,
so no-matter how many scopes are used,, the "Final-focus" is converged at
a "Final-monocular-focal-point".
would that also "combine the 3-scopes Light-gathering power"???
[just my theory,,and I dont claim any basis on fact].

John.
