Details from the web:
Most filter wheels are too large to use with HyperStar because they block so much of the telescope aperture. Our new Filter Slider allows for easy exchange of different filters without removing the camera from the HyperStar lens.
The Starizona Filter Slider is unique by being perfectly circular with no handles or other protrusions that could interfere with the light path. The body of the filter slider is small enough in diameter that it adds no significant obstruction to the telescope, even with an 8" HyperStar.
