PS: I felt I had to clean it because the glass was covered with the kind of marks that dirty rain leaves on a car's window. And I mean covered. -- Joe --- On Fri, 2/6/09, Rodger C.

I have been told by several opticians only clean if you absolutely have to. The micro scratches that can result from aggressive cleaning can cause more optical degradation than dust and film on the surface of the optic.

Joe, Let me know how you clean your corrector plate and how it comes out. My 10" is three years old and I have yet to clean it but someday I will need
to. With the UHTC coating I am hesitant to do anything.
Good Luck in cleaning this.

That's one frosty corrector plate. I've never seen anything like it! - Kurt
