The Moravian C3-26000 PRO is a cooled monochrome astronomy camera with Sony's back-illuminated APS-C IMX571 sensor in industrial grade. It is intended for observatories that run cameras for far more than the roughly 300 hours a year Moravian rates for consumer-grade sensors.
Its 3.76 µm pixels hold over 50,000 electrons. Two conversion paths switch at gain 2750 (about 9.7 dB): below it, full well reaches 52,800 e− with 3.51 e− read noise; above it, read noise drops to about 1.46 e− for short narrowband exposures. Gain is programmable from 0 to 36 dB with full 16-bit digitisation.
On-board RAM holds several full frames, and a full frame downloads in about 0.22 s over USB 3.0. An internal mechanical blade shutter allows automatic darks. The camera accepts an internal filter wheel or Moravian's S, M and L external filter wheels, and an off-axis guider (M68 × 1, 61.5 mm back focus).
