Primary mirror repair needed

[bojan]

Nick, it is pyrex and it looks quite good after washing. Only couple of marks along where the edge of secondary hit and rolled over before falling behind the primary. I was lucky :-)
But the secondary I have to replace since the chip almost 1 cm thick is missing :-( (I am still chasing Chi Qing C,o apparently he has a suitable one but I do not know his address to send him payment for it)

Bojan, I haven't dealt personally with Chi Qin Co, but by all reports, are supposed to be pretty good at what they do. They will be able to verify my previous comments (hopefully) about the situation with removing SiO overcoat from your pyrex mirror. However, it's good news you don't have to get it recoated, but I agree, you may as well replace the secondary mirror.
Cheers
Nick

Hi guys,

Recently I tried to contact Isaac on his hotmail address (I still need that mirror resurfacing.. ), but the message bounced back.

Does anybody knows he is still in this business?

As an alternative, as anybody here used Saintech for recoating?

Saintech do my coatings - Wayne Sainty is ex CSIRO head of thin films - got to be one of the best coating plants in Australia and can do enhanced coatings too.
