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.
The Filter Slider with holder inserted
The filter holder slides easily in and out of the filter slider body, making it simple to change filters in the middle of an imaging session. Each holder uses small but powerful magnets to lock in place against matching magnets in the main body. The magnets are strong enough to prevent any slipping but allow for easy removal of the holder when it's time to change filters.
The Starizona Filter Slider is designed to be simple to use. The filter holder slides easily into the main body. Tapered edges guide the filter holder into place for easy switching of filters in the dark. Once fully inserted, the filter holder is held in place securely and precisely. Rounded notches on the outside of the filter holder make it easy to grip with your fingers to remove the holder.
The Filter Slider is only 17.5mm (0.69") thick, so it will work with most CCD camera and HyperStar lens combinations. New HyperStar adapters are available (see links below) that are shorter in length to accommodate the thickness of the Filter Slider.

The standard system is designed to hold 2" mounted filters which have a standard 48mm thread*. The body has female M48 threads on the HyperStar side and male T-threads on the camera side.
One filter holder is included with the Filter Slider. Additional drawers can be purchased separately to hold multiple filters such as an LRGB set or narrowband set.
