Description

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 filter wheel, FW8S-Aluma filter wheel, and STC-428-P camera with integrated filter wheel.

This insert 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.

Use one insert for each 1.25″ filter.

Very useful for specialty filters that may not be available in the larger unmounted size.
