Mirror silver coating update

[gb_astro]

After another couple of silver coating jobs that were not up to scratch, including my own 14.5",
Wayne of Saintech has decided to stop offering silver as a mirror coating option.
Wayne is still working on getting silver right but at the moment it is off the menu.
He is still offering standard and enhanced aluminium coatings.

Sorry to hear that greg especially after your extended wait for your mirror, which coating are you going for?

Hi Phil.
We are giving Saintech another chance with his Enhanced Aluminium.
Apparently this involves of two overcoats of 80 nanometre silicon dioxide.
Reflectivity is quoted at 96%.

Greg, we are all hoping the final outcome makes all of this agony worth it....

Well it all started with a dishonest USA mirror manufacturer supplying shonky interferometry data ( "0.96 Strehl ! ) with a sub standard mirror....
