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

[ZenAstro <zenastro@home.com>]

I've used the 1.25 inch Lumicon UHC filters (in the cells) in my 
binoculars. I guess I was just lucky they fit just right in the rubber eyecups.

You could always get an optician to cut them to size from a larger filter.

Keep an eye on the exit pupil recommendations to match the filter to the 
binoculars and the sky conditions.  Lumicon has that info.
