Hmm methinks someone wants to copy my setup
Dunk, at the risk of receiving virtual kicks under the table from others here, I'm going to suggest the novelty of the refractor will wear off. While at first it seemed like A Really Good Idea™, I hardly use my 102mm ED f/7 these days.
However 700mm is a useful focal length for photographing the moon or a solar eclipse with say an APS-C or m4/3 camera body.
