Details*Please Read This Important Note Regarding the HyperStar C925...
The HyperStar C925 lens will ONLY work with factory-equipped Fastar-compatible telescopes. This means older 9.25" telescopes are NOT compatible. The older telescopes cannot be retro-fit with a conversion kit like the other size SCTs. This is because the opening in the 9.25" corrector plate is smaller than the diameter of the secondary mirror, meaning the mirror cannot be removed from the telescope.
To determine if your telescope is compatible, check out the secondary mirror assembly on the front of the scope. If it looks like the picture below, you are all set. If not, the HyperStar lens will not work.
Starizona HyperStar 3 Lens - 9.25" Celestron
Only new, factory-equipped Fastar-compatible 9.25" SCT telescopes have a removable secondary mirror assembly, allowing the use of the HyperStar C9.25 lens. Older 9.25" SCTs are NOT compatible, nor can they be converted.
Introducing the new HyperStar C925 Lens. Now 9.25" SCT owners can join the HyperStar revolution. Ultra-fast, wide-field CCD imaging has never been easier. HyperStar quickly converts your SCT into a fast imaging system. The HyperStar lens easily replaces the secondary mirror in the telescope, allowing a camera to be placed in front of the telescope. Switching between HyperStar and standard configurations is quick and simple--no tools required.
The HyperStar C925 lens converts a standard Celestron 9.25" SCT from f/10 to f/2.3, making the system 18 times faster. That means 18-times shorter exposures! Now you can capture deep-sky images without guiding and without an equatorial wedge (in alt-az configuration). The HyperStar lens shortens the focal length of the telescope, giving a much wider field of view, and giving a greater tolerance of tracking errors, allowing for unguided, alt-az imaging.
The HyperStar C925 is compatible with a variety of cameras, including both CCDs and DSLRs. Like the other 8" and larger HyperStar models, the HyperStar C925 covers up to a 27mm (APS-size) sensor. Separate adapters are required for different cameras. One adapter is included with the HyperStar lens. Optical performance is excellent, with a coma-free, flat field of view almost 3 degrees wide.
What telescopes are compatible?
Why are the other HyperStar lenses faster? The 9.25" SCT uses a slightly different optical configuration, in order to produce a flatter field of view and have a smaller central obstruction. This means it uses a slower primary mirror (f/2.3 versus the f/2 mirror in other SCTs). This means the HyperStar has to be slightly slower to retain its excellent optical performance. The difference between f/2.3 and f/2 is negligible.
Starizona Filter Slider
The Starizona Filter Slider is the perfect way to use multiple filters with HyperStar. Most filter wheels are too large to use with HyperStar because they block so much of the telescope aperture. Starizona's new Filter Slider allows for easy exchange of different filters without removing the camera from the HyperStar lens. Furthermore, 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.
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.
