The two-stage cooler, powerful fans, and advanced heat sink designed using thermal flow simulation combine to produce typical cooling delta from ambient of -50C.  This is quite a feat considering the Aluma CCD’s very compact and lightweight package.\u003c\/p\u003e\n\u003cp\u003eSmartCooling automatically adjusts the fan speed to optimize cooler performance and power consumption.  The camera’s firmware is constantly monitoring the sensor and heat sink temperatures, as well as controlling the cooler power.  When full cooling power is needed – when ramping down or running near full power – the fans ramp up to their maximum speed, resulting in the strongest possible cooling.  When less cooling power is needed the fans automatically slow to reduce noise levels and power consumption. SmartCooling also prevents any possibility of overheating by backing off power if the heat sink gets too hot – so you don’t need to worry if your camera is baking in a hot observatory during the day.\u003c\/p\u003e\n\u003ch3\u003eAdvanced Software Included\u003c\/h3\u003e\n\u003cp\u003eAll Aluma CCD cameras come with our MaxIm LT software – a $249 value!  MaxIm LT is a special version of our venerable MaxIm DL software that provides complete control of your camera, filter wheel, and autoguider, plus advanced image processing capabilities.  If you wish you can upgrade to MaxIm DL Pro to get complete observatory integration and even more processing and analysis capabilities.\u003c\/p\u003e\n\u003ch3\u003eIncluded Accessories\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003e\n\u003c\/h3\u003e\n\u003cp\u003eEach Aluma CCD camera package includes:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMaxIm LT software – please use\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/diffractionlimited.com\/maxim-lt-registration\/\"\u003ethis form\u003c\/a\u003e\u003cspan\u003e \u003c\/span\u003eto request your license\u003c\/li\u003e\n\u003cli\u003eDeluxe carrying case\u003c\/li\u003e\n\u003cli\u003eUniversal power supply (110V \/ 220V, 50-60 Hz)\u003c\/li\u003e\n\u003cli\u003e2″ Nosepiece adapter\u003c\/li\u003e\n\u003cli\u003eUSB flash drive containing software, drivers, and documentation\u003c\/li\u003e\n\u003cli\u003e15 foot (4.5 m) USB cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eOptional Micron-Precision Filter Wheel\u003c\/h3\u003e\n\u003cp\u003eThe optional FW8S-Aluma 8-position filter wheel includes a positive centering mechanism that precisely centers each filter in the exact same position every time.
