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.
