Starizona Cool Edge Quick Manual

The Cool Edge allows for rapid thermal stabilization of the air and optics inside your Celestron Fastar­compatible telescope. By moving filtered air through the optical tube, distorting tube currents and heat
spikes are eliminated.

Included Items

• Cool Edge SCT Cooler

• AC or DC Adapter (user selected)

Above: Cool Edge for 14” Telescope

No tools are necessary for the installation and use of the Cool Edge

Position the Telescope

Begin by pointing the telescope tube upward at about a 45-degree angle. This allows you to safely
remove the secondary mirror without the chance of it falling out.

Removing the Secondary Mirror

All Celestron Fastar-compatible telescopes are equipped with removable secondary mirror assemblies,
allowing the easy removal of the secondary mirror for use with a Hyperstar lens or the Cool Edge.
Simply rotate the outer ring around the secondary assembly counterclockwise to unthread it from the
telescope. The secondary mirror can now be lifted out of the telescope.

Placing the Mirror in the Cool Edge

Note the position of the notch in the top threaded ring of the Cool Edge and the matching set screw in
the side of the secondary mirror housing. Carefully set the mirror into the Cool Edge with the set screw
in the notch.
