ATR3CMOS M42+2” USB3.0 TE-Cooling CMOS Astronomy Camera

ATR3CMOS M42+2” USB3.0 TE-Cooling CMOS Astronomy Camera is a high-sensitivity imaging device for astronomical observation and low-light applications. It uses SONY Exmor, Exmor R, or Exmor RS CMOS sensors with a two-stage Peltier cooling system to reduce dark current. The camera features USB3.0 data transfer, smart internal heat dissipation, and supports multiple operating systems via SDKs. Available in several sensor models with varying resolution, pixel size, and cooling performance.

  • Two-stage Peltier cooling reduces dark signal for long-exposure astrophotography
  • USB3.0 interface enables high-speed data transfer and power delivery
  • Multiple sensor options (IMX571, IMX533, IMX269, IMX183, MN34230PLJ, IMX294, IMX428) to match specific imaging needs
  • Supports 1×1 to 9×9 binning for flexibility in speed and sensitivity
  • Wide exposure range from 0.1ms to 3600s for capturing faint celestial objects
  • Cross-platform SDKs for Windows, Linux, macOS, and Android for custom integration

FAQ

What sensors are available in the ATR3CMOS series?
Available sensors include IMX571 (26M), IMX533 (9M), IMX269 (21M), IMX183 (20M), MN34230PLJ (16M), IMX294 (10.3M), and IMX428 (7.0M).
Can the camera be used with a telescope?
Yes. The M42 mount with 2” adapter allows direct attachment to most telescope systems.
Is cooling effective for long exposures?
Yes. The two-stage Peltier system reduces sensor temperature and dark current, ideal for exposures over 10 seconds.
What operating systems are supported?
Windows, Linux, macOS, and Android via native SDKs including C/C++, Python, Java, and DirectShow.
What is the maximum frame rate?
Up to 216 fps at 584×440 resolution with 9×9 binning on the 21M model; 133 fps at 1600×1100 on the 7M model.
