The ASI585MM Pro is a cooled monochrome astronomy camera using the Sony IMX585 sensor. Its 11.136 × 6.264 mm imaging area records 3840 × 2160 pixels with 2.9 µm pixels and a native 12-bit ADC.
Imaging performance
ZWO specifies 38,700 electrons full-well capacity, peak quantum efficiency of 91% and read noise of 0.7–6.4 electrons. The listed capture rate is 46.9 fps USB 3.0 RAW8; 23.7 fps RAW16 at full resolution; actual transfer speed depends on image size, ADC/output mode and USB connection. Monochrome imaging allows separate luminance, colour and narrowband exposures using suitable external filters.
Cooling and data transfer
Two-stage TEC cooling reduces thermal signal during long exposures. The manufacturer cooling specification is Two-stage TEC; 30–35 °C below ambient, tested at 30 °C ambient. A 512 MB DDR3 buffer and USB 3.0 connection support reliable downloads.
Connections and power
The camera connection is M42 × 0.75, with sensor spacing of 6.5 mm bare; 17.5 mm with 11 mm ring. The protective window is 32 × 2 mm AR-coated window. Use a 12 V DC, 3–5 A supply with a 5.5 × 2.1 mm centre-positive connector; the recommended battery range is 11–14 V. Include adapters and any filter wheel when calculating telescope backfocus.
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.
