ATR2600M

ATR2600M Deep Sky Cooled Monochrome Camera

ATR2600M is a professional astronomy camera that combines high precision, high sensitivity, and high stability. Featuring a Sony back-illuminated IMX571 monochrome sensor, native 16-bit ADC with 14 stops of dynamic range, readout noise as low as 0.883e⁻, zero amp-glow, and high full well mode up to 100ke⁻. Its extraordinary performance will give astrophiles a great astrophotography experience.

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.

512MB DDR3 Memory Buffer

ATR2600M camera has a 512MB (4Gb) ultra-fast memory buffer to ensure stable image transmission, easing the burden on your computer's transmission system.

Native 16-bit ADC

ATR2600M is a high-dynamic range astro-camera. Its native 16-bit ADC achieves a true dynamic range output of 14 stops, which ensures the delicacy and accuracy of the image, and the grayscale transition is smoother and more natural.

Zero Amp-Glow

ATR2600M has been carefully designed 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 enhances the stability and durability of the camera, meaning you'll capture sharper, cleaner images in both long and high exposure modes.

Cooling System

Two-Stage TEC Cooling System

ATR2600M 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.

Anti-Dew Technology

ATR2600M 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.
