Do you have experienced mirror makers at a local club that can
guide you Curtis?. If you don't, I would go somwewhere around
F/7 and get a good Barlow as someone else suggested. If you do
have accessable help, then I'd go straight into a Cassegrain of
some kind, preferably a Ritchey Cretien of 10" or 12". Your
helpers would I'm sure enjoy the challenge. You could then maybe
make a 6" F/5 first as your spotter scope :). But that's just me
:)
