The SBIG FW8S-Aluma is the standard (non-guided) 8-position filter wheel for Aluma Series cameras. This filter wheel does not have a built-in self-guiding CCD. It is compatible with Canon EOS and Nikon lens adapters.
The carousel holds eight 36mm filters and inserts are available for 1.25″ filters. The 36 mm filters provide unvignetted imaging for the largest Aluma sensors.
Aluma wheels include a positive centering mechanism that precisely centers each filter in the exact same position every time. This single-pixel accuracy completely eliminates ghost images of dust spots and other artifacts after flat-fielding. This high precision results in the highest quality images and excellent photometric accuracy.
