[APML] Off Topic - Where can I find small size light pollution filters?

["Tom & Lou Krajci" <krajcit@3lefties.com>]

Pardon the OT post, but maybe someone can help me.

I'm trying to find small size light pollution filters for some binocular
eyepieces.  Mounted/cell size of .965 inch diameter would work, and
unmounted size of 0.75 inch diameter would also work.  I'm trying to find
narrow band filters, such as the Lumicon OIII and H-Beta.  (Bill Vorce of
Telescope Warehouse has some .965 mounted Deep Sky filters...but they are a
bit wider passband than I would ideally prefer.)

I also called Lumicon and they said they don't carry filters in anything
smaller than 1 1/4 inch.

Any ideas on suppliers?

Thanks in advance,
Tom Krajci
