The ASI4400MC Pro is a cooled one-shot colour astronomy camera using the Sony IMX366 sensor. Its 36 × 24 mm imaging area records 8192 × 5460 pixels with 4.4 µm pixels and a native 14-bit ADC.
ZWO specifies 74,600 electrons full-well capacity, peak quantum efficiency of 80% and read noise of 1.1–7.6 electrons. The listed capture rate is 8.3 fps, full frame USB 3.0 RAW8 high-speed; actual transfer speed depends on image size, ADC/output mode and USB connection. The colour sensor records colour in a single exposure sequence, supporting deep-sky imaging without separate RGB filter exposures.
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.
The camera connection is M54 × 0.75 female, with sensor spacing of 12.5 mm bare; 17.5 mm with tilt plate. The protective window is 60 × 2 mm UV/IR-cut 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.
