The SBIG FW7-STX is a 7-Position, 50mm square filter wheel for STX, Aluma AC4040, and Aluma AC2020 cameras.
Can also be used with an STL camera, using an ACC10 Adapter.
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.
Please note that this wheel is not compatible with Aluma AC455.
Windows 32 and 64 bit OS, Mac
