[ATM] Multicoatings

[Chris Dalla Piazza]

Here's another way to ask the question.  What do Meade, Celestron, Televue, 
Takahashi, and Astro-Physics use to coat the optics on their refractors and 
the corrector plates of their catadioptrics?  If I needed to get a corrector 
plate from my SCT recoated, where would I do this and what would I ask for?

This is for the corrector of my recently completed Lurie-Houghton Newtonian.

Thanks again for suggestions!
