ATR183C | Sony IMX183 20MP Câmera colorida resfriada

ATR183C câmera colorida refrigerada para deep sky

ATR183C features a Sony IMX183 1-inch sensor with 5440×3648 resolution and 2.4μm square pixels. The camera supports binning mode, equipped with two-stage TEC cooling system (temperature deviation within ±0.1°C), dew prevention heater, built-in 12-bit ADC, 15ke full well, and supports high frame rate mode (8.6 fps@12-bit / 17 fps@8-bit RAW).

Importante: Todas as câmeras DSO refrigeradas precisam ser conectadas a uma fonte externa de 11-14V. Recomendamos usar o adaptador incluso ou uma bateria de íons de lítio com saída estável de 11-14V.

ATR183C camera has a 512MB (4Gb) ultra-fast memory buffer to ensure stable image transmission, easing the burden on your computer's transmission system.

Sistema de resfriamento

Two-Stage TEC Cooling System

ATR183C features a two-stage Thermoelectric Cooling (TEC) with controllable fan, allowing the sensor to operate at temperatures up to 42°C below ambient. The exposure time can be set for up to 1 hour, ensuring every detail is captured.

Efficient Cooling Design

The integrated heat dissipation structure and efficient cooling module ensure stable operation even in summer, maintaining cooling temperatures of -5°C to -10°C throughout the night. Temperature deviation is controlled within ±0.1°C.

Tecnologia antiorvalho

ATR183C adopts advanced anti-dew technology with a heating function consuming about 5 watts (can be turned off via software). The dew heater at the protection window has 4 adjustable levels, allowing users to optimize for their conditions.
