The SBIG FW7-STX is a 7-Position, 50mm square filter wheel for STX and Aluma AC series cameras.

Works with the STX Guider or StarChaser SC-3 for self-guiding with the sensor in front of the filter wheel.

Can also be used with an STL camera, using an ACC10 Adapter.

Compatible filters are available at additional cost – please see Optical Filters.

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.
