Starizona HyperStar 4 with Filter Slider
for Fastar Compatible Celestron 9.25″ non-EdgeHD SCT

The Starizona HyperStar 4 C925 is designed for Fastar-compatible Celestron 9.25″ non-EdgeHD Schmidt-Cassegrain telescopes. The HyperStar 4 lets you image at an amazingly fast f/2.2 with a field of view up to 3.0°! The HyperStar is perfect for cameras from many major brands, including Meade, Orion, Atik, SBIG, Mallincam, Starlight Xpress, and many more. Select your camera from the drop-down menu above and we will send you the proper camera adapter. If your camera is not on the list, please write it into the field provided. It is also important that you give us your secondary housing and the mount style you plan to use with the Hyperstar. This way, we can make sure you hit the ground running!

Modeled after Celestron’s ingenious Fastar feature, HyperStar by Starizona allows Celestron Schmidt-Cassegrain telescope secondary mirrors to be removed. Replacing the secondary mirror with the HyperStar Lens enables a CCD camera to be mounted in front of the telescope. This makes imaging much faster while providing a wider field of view.

Shifting from the HyperStar system to the telescope’s regular f/10 configuration is a simple, easy process that does not require any tools. Since the telescope’s secondary mirror is indexed, re-collimation is not necessary. Learn how to install your HyperStar in the comprehensive video below!

Starizona Filter Slider System

Starizona’s Filter Slider System provides the perfect method for using multiple filters with the HyperStar. Most filter wheels are not compatible with HyperStar since they are too large and obstruct a significant portion of the telescope aperture. This new Filter Slider enables easy filter exchange without the need for detaching the camera from the HyperStar lens.

This unique device is perfectly circular and has no handles or other protrusions that could conflict with the light path. Filter Slider body features a small enough diameter that it contributes no significant telescope blockage. At only 17.5″ (0.69″) in thickness, this Filter Slider is compatible with most CCD camera and HyperStar Lens combinations.

The filter holder slides in and out of the filter slider body effortlessly, making filter exchange during imaging sessions a breeze. This holder utilizes tiny yet powerful magnets to lock in place against matching magnets in the main body. These magnets are strong enough to inhibit slipping while allowing for simple holder removal when it comes time to change filters. Tapered edges help navigate the filter holder into place for easy filter switching at night. As soon as the filter holder is fully inserted, it is securely and precisely held in place. Rounded notches on the exterior of the filter holder enable it to be gripped by your fingers for easy removal.

When ordering your HyperStar it is important to specify the camera being used in the drop down above. If your camera is not included in the drop-down, please enter it manually in the field provided. If we have any questions or concerns a member of our telescope customer service team will contact you. While HyperStar lens assembly works with a various amount of cameras, some of them require different adapters. The proper adapter will be included, and so will a holder for safe storage of the secondary mirror while imaging.
