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).

Greg, for a finder you won't notice any difference re:

The last time I got new eyeglasses, anti-reflection

essentially. So I"m pretty sure that there are local
labs who can do it.
