The ASI585MM Air combines a monochrome Sony IMX585 imaging sensor and a separate monochrome SC2210_BW guide sensor in one housing with integrated ASIAIR control.
Imaging and guiding
The main sensor records 3840 × 2160 pixels at 2.9 µm with a 12-bit ADC. Its full well is 38.7 ke. The guide sensor records 1920 × 1080 pixels at 4 µm, with 8780-electron full well and peak QE of 92% at 500 nm. Monochrome operation supports separate LRGB and narrowband filter exposures.
Cooling and optical window
Two-stage TEC cooling provides 30–35 °C below ambient in ZWO’s 30 °C test conditions. A software-controlled 2.4 W heater helps protect the ar-coated window from dew. Cooling performance varies with ambient temperature and operating conditions.
Control and connections
Built-in 256 GB eMMC storage and 2 GB DDR4 memory accompany four USB 2.0 accessory ports and dual-band Wi-Fi. Export files by USB drive or USB Type-C computer connection. The three DC ports can act as input or output, but only one may be connected to an input supply at a time.
Power and spacing
Use 12 V DC, 3–10 A with a 5.5 × 2.1 mm centre-positive connector and the specified 11–14 V battery range. The M42 × 0.75 interface provides 12.5 mm bare; 17.5 mm with 5 mm tilt plate. Include all adapters and filters when calculating telescope spacing.
Use the exact named-model manufacturer connection and operating instructions linked with this product. Optional parts and adapters require their specified spacing and power limits.
