Imaging performance
ZWO specifies 51,400 electrons full-well capacity, peak quantum efficiency of 91% and read noise of As low as 0.86 electrons. The listed capture rate is 6.3 fps advertised maximum (current P25 table); 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 M54 × 0.75, with sensor spacing of 17.5 mm standard assembly. The protective window is 60 × 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.
