2 inch clear glass filter

[astro mick]

Hi anyone know where i can get a good optically flat clear glass filter to act as a dust protector on my refractor.

I have recently bought a filter on Ebay,but unfortuately,the outer wall is slightly to thick to slide into my Focusser.

Basically it needs to screw into my flip mirror,and then slide into the focusser.

Any ideas.

Mick.

May be a Baader IR block filter? It's clear glass in the visible spectrum

Baader sell a 2" 'clear' filter, think 365astronomy had them last time I looked.
