Celestron 9.25

This Schmidt-Cassegrain has an almost mythical reputation.  Is it deserved?  The primary (pun!) difference between this scope and just about every other SCT is that it alone has an f/2.3 primary vs. an f/2.0 primary.  F2.0 is awfully unforgiving in collimation and hiding figure errors.  Does that make so much of a difference?  Some think the quality control is better.  

One thing that is undeniable: it's a big, heavy scope, considerably bigger and heavier than an 8" (23-lb).
