 Introducing the new TEMP-est TEMPerature Equilibration System for Telescopes from Deep Space Products. The first models of the TEMP-est are designed for use on the Celestron Edge HD Schmidt-Cassegrain telescopes ("SCTs") and new standard SCTs with built-in side vents. The TEMP-est Categories 2 through 3 consist of one or two components for these telescopes: an active venting system that replaces the passive vents in the rear cell of the OTA and a second fan system that is placed in the Fastar secondary hole for quick initial cool-downs. The vent fan system is designed to be run while using the telescope and employs one filtered fan to pull air out of the OTA and another filtered fan to push air into the OTA. The filtered fans use a 55 micron stainless steel filter to keep dust input to a minimum. The filter can be removed from the exhausting fan by the end user to increase air flow. The vent fan systems run off of standard 12VDC with a 2.1mm or 2.5mm center positive plug and the vent fans are wired together so that only on power supply is need to run both vents. The C9.25 version is still in planning. All of the Fastar fans run on 12VDC with a 2.1mm or 2.5mm center positive plug. The fans on both sides of the OTA have power sockets for convenience and can be daisy-chained with the Fastar fan. The fans being used for the vents are high quality magnetic levitation fans that offer the highest flow while minimizing vibration. The purpose of the vent fan system is to help the primary mirror and interior air remain as close to ambient temperature as possible in order to minimize the formation of tube currents in the OTA and to do this while using the scope for viewing and imaging. Each vent assembly is custom CNC-machined for the OTAs and made from materials like solid surface acrylic polymer and recycled materials are used when available. The vents can be made in a variety of colors depending on available supplies. We currently have Black Hole (solid black), Sunset (solid orange), Sun (solid yellow), Fireball (solid red), Night Sky (flecked black), Cloudy Night (very slightly flecked black), Red Giant (dark red flecked). The Fastar fan assemblies will be of random colors but can also be made to match the vent fans (depending on material availability). We may also be able to provide other colors upon request for an additional fee. Power cables can be ordered along with the fans for connection to your 12VDC power supply. The vent fans only require a single cable since they are connected together inside the back of the scope. The Fastar fan requires a separate cable but can be wired in a "Y" along with the vent fan cable. The cables are 6 feet long and have either the 2.1mm or 2.5mm plug on one end and are bare on the other end so that you can add whatever type of power connection you like (e.g., cigarette lighter, power poles, RCA connectors, alligator clips, etc.). For the ultimate in temperature stabilization, the TEMP-est Category 4 for C11 and C8 scopes includes our Black Hole carbon fiber tubes in standard and custom colors. To order a Black Hole tube for your C11 or C8 please go to the following page: Category 4 TEMP-est fans will be installed for free with HyperTune OTA services.
