The ZWO ASI 2400MC PRO features the full-frame Sony IMX410 sensor with large 5.94 µm pixels and a full well depth of 100,00 eˉ. With quantum efficiency of up to 80% and a ultra-low 1.1 eˉ readout noise, the 2400MC Pro is a very capable camera for the serious astrophotographer.


Sony’s back-illuminated CMOS technology improves sensitivity, minimizes noise, reduces power consumption and increases data download speed. In a conventional front-illumination structure, the interconnection of metal wiring and transistors are above the photosensitive silicon surface (photo diode), reducing the overall sensitivity and therefore the quantum efficiency. In back-illuminated sensors, the photosensitive surface is placed on top of the wiring so the incoming light is not obstructed, resulting in a greater quantum efficiency. Sony has developed a new and unique photo-diode structure and an on-chip lens that is optimized for back-illuminated structures, achieving a higher sensitivity and a lower random noise.

The ASI2400MC Pro features a 14bit ADC that can achieve a dynamic range output of 14 stops. This improves the image sharpness and contrast significantly and the color shades are smoother and more natural.

When the gain value is 140, the HCG high gain mode is automatically activated and the readout noise is greatly reduced (as low as 1.1 eˉ) while the dynamic range basically remains unchanged.


The ZWO PRO cameras incorporate a 256MB DDR3 memory buffer that improves data transfer reliability and it minimizes amp-glow caused by slow data transfer speeds.

The USB 3.0 Port provides 5Gbps bandwidth and lets the camera run at 8fps at full resolution (26 Mega).

The USB 2.0 Hub allows to connect 2 USB controlled accessories such as a filter wheel, a guiding camera or an electronic focuser, reducing the amount of cables that run directly from your computer.

The 2 stages TEC cooling system allows a ΔT of 35°C below air temperature. The cooling system requires an external power supply of 12V at 3-5A with a 2.1×5.5 mm connector (positive tip). The ASI 2400MC can be powered with a standard lead battery or a DC source between 9-15V.

The dew heater avoids the problem of dew condensation on the optical window of the sensor. The heater can be turned off via software.

Traditional CMOS sensors produce a weak infrared light source that is often seen in the corner of uncalibrated images as bright glow. The ASI 2400MC uses the zero amp glow circuits that avert this artefact in your images.
