8-Position, FW8G-STXL Self-Guiding Filter Wheel with Micron-Precision filter positioning.

Allows the use of Nikon or Canon EOS lens adapters

Repeatable filter positioning to better than a pixel, holds eight 50mm round unmounted filters.

Standard 8-Position Filter Wheel

The FW8S-STXL is identical to the FW8G-STXL filter wheel except that the Standard version does not have a self-guiding CCD built-in to the front cover. The filter mechanism is the same, however. In fact the wheels share the same base, and the covers interchangeable. If you have the Self-Guiding version you can add just the Standard cover if you wish to use the STXL camera lens adapters for Nikon or Canon EOS lenses.

Micron-Precision Filter Positioning

Micron-Precision Filter Positioning

Both the Standard and Self-Guiding versions of the STXL filter wheels incorporate the same micron-precision filter positioning mechanism as the STT Series cameras. When taking flat field frames of filtered images, the flat field frame must show exactly the same optical characteristics to be the most effective. If there is dust on the filter, or uneven illumination caused by the filter, this must be represented precisely as seen in the light image to be corrected by the flat field frame. The STXL filter wheel is designed to provide a new level of accuracy when taking flats through filters by repositioning filters to within a few microns every time. This allows the imager to take extremely accurate flat field frames even after rotating the filter wheel several times, or even after a loss of power.
