Starizona's Cool Edge is designed to help rapidly stabilize your telescope with the ambient air temperature.
The Cool Edge is designed with Celestron's new EdgeHD optical system in mind. Because this telescope design has lens elements inside the primary baffle tube, it is not possible to use a traditional SCT cooler that pushes air through the back of the telescope. But the EdgeHD telescopes combine rear-cell air vents with Fastar-compatible optics, allowing the Cool Edge to work from the front of the scope.
The Cool Edge will also work with any Fastar-compatible SCT by simply leaving the scope's visual back open (by removing the diagonal) to allow the air to flow through the optical tube.
