Thread the retaining ring from the telescope onto the Cool Edge to hold the mirror in place. Do not
over-tighten this ring as temperature changes can make it difficult to remove.
Attaching the Cool Edge to the Telescope
Thread the entire Cool Edge assembly onto the front of the telescope. Again, do not over-tighten the
cooler to avoid it being difficult to remove later.
Ventilating the Telescope
The new Edge HD telescopes include rear cell vents to allow air to flow through the telescope tube.
Standard (non-Edge HD) telescopes will require the back of the telescope to be open to allow air flow.
Simply remove the diagonal from the visual back of the telescope to let air move through the telescope
tube. Removing the diagonal is not necessary with an Edge HD telescope.
