Theres a 16" F5 Newtonian on Ebay located Melbourne.
I'm posting this on behalf of Matt Hocking who is not a member , so I can't answer questions about the telescope other than as to the optical quality as the optician. He informs me that the materials alone cost a lot more than the asking price, which makes it a very good buy. Matt is a very capable young engineer, and doesn't seem to do anything by halves, and needs to sell the scope to pay University debts.
He is happy to sell privately and can be contacted on:
