Introducing the new HyperStar C9.25 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.
Features
The HyperStar C9.25 lens converts a Celestron Edge HD 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 C9.25 is compatible with a variety of cameras, including both CCDs and DSLRs. Like the other 8" and larger HyperStar models, the HyperStar C9.25 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.
FAQs
What telescopes are compatible?
The Edge HD 9.25" SCT telescope has a removable secondary mirror assembly, allowing the use of the HyperStar C9.25 lens.
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.
