Starizona HyperStar 4 with Filter Slider
for Fastar Compatible Celestron 8" SCT

Starizona's HyperStar 4 allows you to capture images with incredible speed and an even wider field of view than previous models. The HyperStar 4 is an imaging accessory that takes the place fo your 8" Celestron SCT's secondary mirror. This transforms your OTA into a powerful f/1.9 focal length imaging telescope with up to a 4.1° field of view. This Starizona HyperStar C8 is compatible with Celestron 8" Schmidt-Cassegrain telescopes that are Fastar compatible. Cameras from Meade, Orion, Atik, SBIG, Mallincam, Starlight Xpress, etc. are perfect for the HyperStar C8. Choose your camera from the drop-down 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. In this way, we can make sure you hit the ground running!

Based on Celestron's innovative Fastar feature, HyperStar by Starizona allows the secondary mirror on Celestron's Schmidt-Cassegrain telescopes to be removed. Mounting the HyperStar lens assembly in place of the secondary mirror enables you to mount a CCD camera at the front of the telescope. This provides much faster imaging and a wider field of view.

Switching between HyperStar System to the telescope's normal f/10 configuration is simple, easy and requires no tools. No re-collimation is necessary because the telescope's secondary mirror is indexed.

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.
