SBIG Filter Insert 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 FW5-8300, FW8-8300, FW8S-STT and FW8G-STT filter wheels. Use one insert for each 1.25" filter. Mix 1.25" and 36mm filters in the same filter wheel carousel.
