ATR585C

ATR585C Deep Sky Cooled Color Camera

ATR585C camera incorporates the advanced Sony IMX585 sensor, renowned for its exceptional imaging capabilities for both planetary and deep-sky objects. Engineered with an integrated heat dissipation structure and an efficient cooling module, it enables the image sensor to function at a temperature 45°C lower than the ambient environment. With features including zero amp-glow, STARVIS 2 technology, minuscule pixel size, and a high dynamic range (HDR) mode, this camera is ideal for entry-level deep space photography, offering outstanding performance at a remarkably cost-effective price point.

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. 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.

STARVIS 2 Technology

Enhanced Low-Light Performance

STARVIS refers to the backlight image sensor technology developed by Sony to improve low light characteristics and near-infrared sensitivity. STARVIS 2 improves dynamic range and near-infrared sensitivity compared to STARVIS 1. Benefiting from it, ATR585C shows better performance in both planetary and deep-sky imaging scenarios.

512MB DDR3 Memory Buffer

ATR585C 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

ATR585C is designed with an integrated heat dissipation structure and an efficient cooling module. The cooling system features a two-stage Thermoelectric Cooling (TEC) with controllable electric fan assisting in heat dissipation. This allows the image sensor to operate at temperatures up to 45°C lower than the ambient temperature. The exposure time can be set for up to 1 hour, ensuring that every minute detail is captured.

Efficient Cooling Design

Even in summer, it can still run stably all night with cooling temperatures ranging from -5°C to -10°C. Temperature deviation is controlled within ±0.1°C, ensuring consistent performance throughout your imaging sessions.

Zero Amp-Glow Technology

Clean Long Exposures

ATR585C 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.

Anti-Dew Technology

Advanced Dew Prevention

ATR585C adopts advanced anti-dew technology, which can effectively solve the condensation problem through heating. This heating function consumes about 5 watts and can be turned off via software to save power. Additionally, the dew heater at the protection window has 4 adjustable levels, allowing users to find the heating power that best suits their needs.
