This piece suggests that Peter is endorsing these kind of mirrors. Peter Read has never looked through a scope with a ultra- fast mirror. He is building a few where customers like yourself are supplying their (F2.8 - F3 ? )optics by buying from the optician directly. Please correct me if I have this wrong.

The balance point no more than a few feet off the ground would not suit Sydney Observatories application of looking out of a traditional dome.
