Filter - IR Pass 1.25 inch

Hi all,

I am looking for an infrared pass filter for planetary / PHEMU work.

It will be mounted in a 1.25 inch eyepiece threaded holder.

Should have a passband from around 650nm up past 1100 nm (or thereabouts)

This is known as an IR-Pass filter and is made by Baader and other manufacturers.

Please PM if you have one. I'd expect $130 new or thereabouts, so maybe somewhere around $90 + P&P secondhand.

Regards,
Tony Barry
