So..., who actually makes good mirrors in Australia?
I am looking at 15-16" f4.5.
I have built our house so I think it is not beyond me to build a truss Dobsonian.
I see some ridiculous prices on the net for ready built truss Dobs - it may actually be a rewarding project that could save me some money...and yes I already have the router, bench saw, router table etc...
I would hope that whoever grinds the mirrors can support the finished product with some verifiable claims and has the necessary test equipment.
Or should I just wait for the 16" GSO and hope that I will get better than average mirror with it, from what I have heard the mirror makers do not have a very good opinion of the GSO optics...(not entirely unexpected since they are forced to compete against them)
