Re: [ATM] Multicoatings

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!

I have a few questions about multicoatings I was wondering if someone could
help me with...
Do multicoatings increase transmission or do they only eliminate reflection. 

I understand there are a few different types of multicoatings.  Is there a
standard or most widely used coating?
My priority is that there be no weird colors when imaging rather than really 
high transmission.  What coating would you recommend?

Finally, who would you recommend?
