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.
