This innovative product from Starizona 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.
The Cool Edge attaches to the telescope just like a HyperStar lens would; you simply remove the secondary mirror and thread the Cool Edge on. All Fastar-compatible telescopes ship with easily removable secondary mirrors to allow the use of a HyperStar lens. This also allows the use of the Cool Edge.
