Starizona HyperStar C8 HD Operating Instructions Manual

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.

Parts List

The HyperStar Lens Assembly includes two pieces:

• HyperStar Lens

• Secondary Mirror Holder

Secondary holder (ships attached to lens), & HyperStar lens

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.

3) Unthread the retaining ring from the secondary mirror holder as shown below.

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. Use the original retaining ring to lock the mirror assembly in place.

Attaching the CCD Camera

6) Some CCD cameras require threaded adapters. Begin by removing the plastic cap

from the top (narrow end) of the HyperStar lens and attaching any required adapters.

7) The CCD camera will attach to the HyperStar (or adapter) using T-threads. Most
cameras have a 1.25” or 2” nosepiece that must be removed to allow the HyperStar to
thread into the T-threads.
