This adapter works with the HyperStar 3 Lens for Celestron 9.25" and 11" telescopes, both regular and HD. One adapter is included with the HyperStar lens. Purchase additional adapters for use with other cameras.
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.
