- Captures the entire frame at once to eliminate rolling shutter artifacts, delivering distortion-free images
- Combines ultra-large pixels for high light sensitivity with an anti-reflective (AR) coated glass window to maximize light throughput and prevent ghosting
- Cools the sensor up to 42°C below ambient temperature, reducing thermal noise during long exposures
- Prevent condensation buildup on humid nights with the adjustable power levels built-in dew heater
ToupTek ATR Series DeepSky Astrophotography Camera!
ATR432M features a resolution of 1600x1100 pixels, 9 μm pixels and a 1.1-inch optical format.It offers support for high frame rate mode(109FPS at all Pixel Readout 12 bit),and has a readout noise level as low as 2.4e. Additionally ,the camera have an excellent TEC cooling system maintains precise temperature control within a deviation of 0.1℃, while the dew prevention heater (window heating) further enhances performance.
Please note: all ToupTek Astro DSO cooled cameras can only be powered by 12V3A DC power supply. We recommend using the power adapter that comes with the camera or a lithium-ion battery with stable output of 11-14V. Please do not use power supplies that have falsely stated specifications or unstable outputs to power the camera, as this may affect image capture or even damage the camera.




Sensor Specifications
- ATR432M features Sony IMX 432 1.1inch Format sensor
- Diagonal: 17.5mm
- Pixel Size: 9μm x 9μm


Fast DDR3 Memory
ATR432M camera has a 512MB (4Gb) ultra-fast memory buffer to ensure stable image transmission.


TEC cooling system
ATR432M is designed with an integrated heat dissipation structure and an efficient cooling module. The ATR432M cooling system uses two-stage Thermoelectric Cooling (TEC) with a controllable electric fan to help dissipate heat. This allows the image sensor to operate at temperatures up to 42 degrees Celsius lower than the ambient temperature. The exposure time can be set for up to 1 hour, ensuring that every minute detail is captured. Even in summer, it can still run stably all night with cooling temperatures ranging from of -5°C to -10°C.


Anti-dew technology
ATR432M adopts the new anti-dew technology , which can effectively solve the condensation problem through heating. This heating function consumes about 5 watts, which can be turned off via software to save power.
Additionally, the dew heater on the protective window has four adjustable levels. Users can choose the heating power that best suits their needs.
