The HyperStar Lens Assembly allows CCD imaging at f/2.1 with compatible Celestron
8" HD Schmidt-Cassegrain telescopes and compatible CCD cameras. These instructions
show the proper methods for installing the HyperStar lens and CCD camera on the
telescope, and for collimating the lens for the best optical performance.
For more details on CCD imaging, visit www.starizona.com and see the Guide to CCD
Imaging.
Warning:
When the HyperStar lens and CCD camera are mounted on the telescope,
there is the potential for damaging the corrector plate if caution is not exercised at all
times. Be especially careful not to bump the CCD camera or HyperStar lens while they
are attached to the telescope. Also, be sure that all cables from the CCD camera are
properly tied off to prevent them from pulling on the camera and lens. Additional tips
and warnings are clearly marked throughout the assembly instructions. As long as care
is used, no problems will occur.

- Page 2 Positioning the Telescope 1) Begin by aiming the telescope up at about a 45-degree angle. This will prevent the secondary mirror or HyperStar lens from falling out during installation. Removing the Secondary Mirror 2) The secondary mirror holder doubles as the bottom cap for the HyperStar lens. Begin by unthreading the holder to remove it from the lens.
- Page 3 4) Carefully remove the secondary mirror assembly from the front of the telescope. Do not touch the surface of the mirror itself. 5) Place the secondary mirror assembly into the holder. Note the notch on the side of the secondary holder which accepts the small screw on the side of the mirror assembly.
- Page 4 8) Thread the CCD camera onto the HyperStar lens. 9) Carefully thread the entire assembly into the front of the telescope. Camera orientation can be changed later.
- Page 5 Collimating the HyperStar Lens The HyperStar incorporates a simple collimating system. The three pairs of screws around the base of the HyperStar push and pull to tilt the lens and correct for any alignment error. Warning: Keep in mind that the three pull screws (shown on next page) hold the lens in place on the telescope.
- Page 6 Adjusting Camera Position The third set of screws (labeled above as ) allow the HyperStar and camera to be ROTATE rotated into a different orientation for the purpose of framing objects. Loosen the three screws slightly. The nylon bushings will allow the lens to rotate with the screws still somewhat snug.
