Hi, if you are looking for someone to aluminize/re-aluminize your mirror at a very reasonable price, contact Andrew at
scopes@scopesnz.com
I have had a number of mirrors,(6"-12.5") coated by Andrew. Didn't cost "an arm and a leg". Most recent was the 12 1/2" at a cost of NZ$75 plus GST.
At present his chamber can handle up to 18", but he is thinking of building a larger vacuum tank able to manage possibly up to 700mm (27.5").
Doesn't offer an overcoat at this point in time,but is looking to include this option.
Oh! thought I might take the opportunity to drop a couple of Ronchi pics of where I'm up to with my 33"f4 mirror.
