SBIG Filter Inserts 36mm to 1.25"

Individual inserts that allow the use of 1.25″ filters in threaded cells to be used instead of 36mm unmounted filters in the FW8-8300 and FW8S-Aluma filter wheels. Also works with older STT and self-guided Aluma filter wheels. You can mix 1.25″ and 36mm filters in the same filter wheel carousel.
