CosmicOne SCT Coolers
Schmidt-Cassegrain Telescope Cooler
The CosmicOne SCT Cooler - or "Cat Cooler" - is a device for ventilating the inside of SCTs, Maks, and other catadioptric 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 minutes to 2 hours.
