>> mounting a 5" diameter secondary for R-C

Sounds like serious stuff ... I'd play it safe and make clip holders
a'la Texerau. Silicon is good stuff, but Cassegrain (sorry,
Cassegrainian :-) is notoriously sensitive to miscollimation. A fast
primary and a fair amount of magnification on secondary will make it
HUNDREDS of times more sensitive than an equivalent Newtonian ! A
miniscule increase in diffraction is a small price to pay for a peace
of mind.
