Catadioptric telescopes or SCT's have closed optical tubes at the front. These closed tubes are great for keeping the optics clean, but they prevent air circulation. This lack of circulation limits conductive heat transfer and greatly prolongs the time required for the optical tube to reach the ambient outdoor temperature. The temperature differential between the telescope and the surrounding air cause "heat pillars" and "tube currents". These tube currents cause distortion similar to the wavering mirages you might see on the road on a hot day. Until the telescope tube and the optics it houses reach a temperature close to that of the surrounding environment, it will not give the best images. In fact, fine details on planets or in deep sky objects may be completely invisible while the scope is warm, but they are easily visible when the scope is at ambient temperature.
The CosmicOne SCT Cooler is a device for ventilating the inside of SCT telescopes so that they may be brought quickly to ambient temperature. This allows image ruining tube currents and heat pillars to be minimized in 10-20 minutes instead of the usual 45 - 60 minutes. The greater the temperature difference between the place your telescope is stored and the outside evening air, the more quality viewing time you can reclaim with a CosmicOne SCT Cooler. The SCT Cooler has a filtered air intake and other design features whcih minimize the possiblity of dust infiltration and direct the air flow away from the internal optical surfaces.
