ZWO ASI 183MC Pro Color: 20 megapixel with cooling for long exposures<\/strong><\/h2>\n\n\n\n

The ASI183MC Pro combines the 20.18-megapixel Sony IMX183 color sensor with a two-stage Peltier cooling system that lowers the sensor's temperature by up to 45 degrees Celsius below ambient. This drastically reduces thermal noise, the biggest enemy of long exposures.<\/p>\n\n\n\n

The internal 256 MB DDR3 buffer memory keeps the data flow via USB 3.0 stable, even during long exposure sequences. With 84% quantum efficiency and 2.4-micrometer pixels, the camera captures faint nebulae with fine detail.<\/p>\n\n\n\n

Cooling that makes a difference<\/h4>\n\n\n\n

With minute-long exposures, thermal noise roughly doubles per 6 degrees Celsius of sensor temperature. By cooling to a fixed, low temperature, your captures not only become cleaner but also reproducible: today's dark frames will match next month's light frames.<\/p>\n\n\n\n

For cooling, rely on a 12-volt power supply; the camera weighs 410 grams (14.5 oz).<\/p>\n<\/div>\n<\/div>\n\n\n\n

Honest advice about the sensor<\/h4>\n\n\n\n

Even when cooled, the IMX183 amplifier shows glow during long exposures. Thanks to the stable cooling temperature, a set of dark frames fully calibrates out that glow. Those who prefer to work without that step can choose a glow-free sensor, like the one in the ASI533MC Pro.<\/p>\n\n\n\n

For the money, you get the highest resolution in the cooled color offering here.<\/p>\n<\/div>\n<\/div>\n\n\n\n
