Thanks. The reason that I was asking is that when I was testing it out on Jupiter this morning, the light from the moon reflected off of the plate, causing the field to be washed-out. (I'm somewhat astonished at how razor thin the focal plane is at f/3.64).

I use glass lenses exclusively, prescription safety glasses, essentially. So I"m pretty sure that there are local labs who can do it. C. --- Greg Taylor wrote:
I recently aquired an old celestron comet catcher for use as a super finder on the big scope that I am building. After a few minor repairs, it works very well. My only quam is that the corrector plate is uncoated. Is there anywhere quasi-local where I could get at least a magnesium flouride coating put on it?
