The SBIG FW7-STX is a 7-Position, 50mm square filter wheel for STX series cameras.
Works with the STX Guider, for self-guiding with the sensor in front of the filter wheel.
We recommend 2mm thick, 50mm x 50mm square unmounted filters.
It is possible to install 3mm filters if you do not fully tighten the carousel filter retainer screws.
Thin 1mm filters are not recommended, and will require shims, not available from us.
