Hi Ed,
Awsome
A couple of Q's:
What is the secondary size, it looks about 10".
Is it a Cassegrain secondary (convex) or is it a flat?
I assume the round bit of plate is a baffle, is it tapered to allow for the light cone from the primary or have you just made the top end a little oversize?
BTW what is the F ratio of the primary?
Cheers,
