This is a set of LRGB filters that came with my True Tech Custom Filter Wheel. They are 1-1/4" and I was told they were IR blocking (but I don't know for sure). There are no markings on the filters indicating type or manufacturer. They were used by the previous owner with very good results. I happen to have a set of Astronomiks filters so these are redundant to me. They are in excellent condition and come with a padded plastic case.
I'm asking $125 including shipping CONUS. International shipping slightly more. PayPal only please. I never add a surcharge.
