ATR533M

ATR533M Deep Sky Cooled Mono Camera

ATR533M leverages Sony's advanced optical technology with a 1-inch format mono sensor, boasting 9 megapixels and high quantum efficiency (QE), allowing users to easily capture clearer deep-sky images. With zero amp-glow, ultra-low readout noise as low as 1.1e, and 3.76μm square pixels, it ensures exceptional image quality. The excellent two-stage TEC cooling system maintains precise temperature control within a deviation of ±0.1°C, while the dew prevention heater (window heating) further enhances performance. It is a camera specially created for beginners of deep-sky photography!

Important: All DSO Cooled Cameras need to be connected to an external 11-14V power supply. We recommend using the included power adapter or a lithium-ion battery with stable output of 11-14V. Do not use power supplies with falsely stated specifications or unstable outputs, as this may affect image capture or even damage the camera.

512MB DDR3 Memory Buffer

ATR533M camera has a 512MB (4Gb) ultra-fast memory buffer to ensure stable image transmission, easing the burden on your computer's transmission system.

Cooling System

Two-Stage TEC Cooling System

ATR533M 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. Even in summer, it can run stably all night with cooling temperatures ranging from -5°C to -10°C.

Efficient Cooling Design

ATR533M is designed with an integrated heat dissipation structure and an efficient cooling module. Temperature deviation is controlled within ±0.1°C, ensuring stable operation throughout the night.

Anti-Dew Technology

ATR533M adopts advanced anti-dew technology, which can effectively solve the condensation problem through heating. This heating function consumes about 5 watts (can be turned off via software). The dew heater at the protection window has 4 adjustable levels, allowing users to find the heating power that best suits their needs.

Zero Amp-Glow Technology

Advanced Zero Amp-Glow Design

ATR533M has been carefully designed and is able to achieve zero amp-glow photo shooting. This not only greatly reduces the generation of internal glow, but also effectively suppresses the interference of external light. It also enhances the stability and durability of the camera, which means you'll be able to capture sharper, cleaner images in both long and high exposure modes.
