SBIG Standard Cover for STT Filter Wheel

Canon EOS and Nikon lens adapters are not compatible with the FW8G-STT filter wheel because the back focus requirements of the lenses are too short for the self-guiding version. In this case, one can use the standard cover for use with camera lenses where external guiding is quite acceptable. Guiding with the standard filter wheel can be accomplished using the remote guide head or separate guider like the ST-i.
