HyperStar Conversion Kits
Not all telescopes are inherently compatible with HyperStar. In order to use HyperStar, your telescope must have a removable secondary mirror. The secondary mirror is taken out of the telescope and safely stored when the HyperStar lens is in place.
Starizona offers HyperStar Conversion Kits, which allow non-compatible telescopes to be converted, allowing the use of HyperStar.
Conversion kits are available for Celestron 8", 11", and 14" SCTs. The kit includes three components that replace the original secondary mirror assembly.
To install, the original assembly must be removed from the telescope. The corrector plate is removed first. Then the baffle tube is unthreaded to allow the secondary holder to be removed. The secondary mirror itself is then removed and placed into the new holder. This assembly is then put back onto the corrector plate and reinstalled into the telescope.
After installation the telescope optics must be collimated, but collimation is then retained when the secondary is removed for HyperStar imaging. Removing the secondary mirror is done using a threaded ring. While out of the telescope, the secondary is safely stored in a holder included with the HyperStar lens.
Note: The old orange-tube Celestron SCTs have secondary mirrors which are mounted differently from the current model telescopes. This requires a modification to the Conversion Kit which is an extra $50. Please call to order the Conversion Kit or if you have any questions on which version your telescope requires.
The image above shows a diagram of how the HyperStar Conversion Kit works. The secondary mirror assembly is replaced, while the optics (secondary mirror and corrector lens) are those from the original telescope. Once converted, there is no difference in terms of using the telescope at f/10. The scope is then easily converted between the f/10 and f/2 configurations and back again. Watch this video to see how the HyperStar is installed on a converted telescope.
