It actively pulls heat away from the camera's cooling shield so your sensor runs far cooler during demanding daytime sessions, most notably solar and large-format planetary imaging, where a camera sitting in direct sunlight can otherwise heat up dramatically.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe ACS is for imagers running an uncooled Player One camera equipped with PCS who shoot long solar or planetary sessions in warm, sunlit conditions and want to keep sensor temperature, and the thermal noise that comes with it, under control.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKey Features \u0026amp; Design\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eActive heat extraction:\u003c\/strong\u003e the unit dissipates heat from the camera's shield, taking over where passive cooling alone reaches its limit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt for sunlight:\u003c\/strong\u003e designed specifically for solar and large-format planetary cameras that sit in direct sun for extended periods.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorks with the PCS shield:\u003c\/strong\u003e it relies on the camera transmitting heat from the sensor out to the shield, so the ACS can carry it away.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eCooling Design \u0026amp; Behavior\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003ePlayer One reports that a camera fitted with both PCS and ACS holds its sensor to roughly 7°C above ambient, even under extended direct sunlight, a large improvement over an uncooled body that can climb toward 60°C in the same conditions. In practice the camera body stays a little warm rather than hot, which keeps dark current and thermal noise down through long solar and planetary runs.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eReach for the ACS during solar narrowband and white-light imaging and large-format planetary sessions on hot, sunny days, where sensor heating would otherwise raise noise and shorten how long you can keep shooting.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eCompatibility \u0026amp; Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCamera requirement:\u003c\/strong\u003e the ACS is for uncooled cameras that already carry Player One's Passive Cooling System; the camera must be able to move heat from the sensor to its shield for the ACS to help.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot a replacement for TEC cooling:\u003c\/strong\u003e this is an active air-cooling accessory for uncooled bodies, not a regulated thermoelectric cooler.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eGood to Know Before You Order\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePlayer One does not publish dimensions, weight, or power specifications for the ACS; if you need those details to plan your setup, contact us and we will help.\u003c\/li\u003e\n\u003cli\u003eThe roughly 7°C-above-ambient result applies to a camera running PCS and ACS together, since the ACS is designed to supplement passive cooling rather than work on its own.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eFAQ\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIs it difficult to set up?\u003c\/strong\u003e No. The ACS attaches to a compatible PCS-equipped camera and runs as an active air-cooling unit; there is no imaging-train reconfiguration required.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich cameras is it for?\u003c\/strong\u003e Uncooled Player One cameras that include the Passive Cooling System, particularly solar and large-format planetary models.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow much cooling does it provide?\u003c\/strong\u003e With PCS and ACS together, Player One reports the sensor stays about 7°C above ambient even in direct sunlight.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eBottom Line\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eIf you shoot the sun or large-format planetary targets with a PCS-equipped Player One camera, the ACS keeps your sensor close to ambient through long, sunlit sessions so noise stays low.\u003c\/p\u003e","brand":"Player One Astronomy","offers":[{"title":"Default Title","offer_id":44013787316335,"sku":"ACS","price":99.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/POA-ACS__17601.jpg?v=1766562666","url":"https:\/\/ontariotelescope.com\/products\/active-cooling-system-acs-for-uncooled-cameras","provider":"Ontario Telescope and Accessories","version":"1.0","type":"link"}
