The First Astronomy Camera With a Sony Full-Frame IMX410 Sensor

The ZWO ASI2400MC Pro is a milestone in CMOS astronomy camera technology. Incorporating the Sony’s latest back-illuminated IMX410 14-bit ADC sensor, this 24 megapixel full-frame  camera features big 5.94um pixels that can accommodate a large full-well depth of 100ke and high dynamic range. With an ultra-low readout noise of 1.1e and zero amp-glow, the ASI2400MC Pro is yet another great innovation by ZWO in the field of full-frame cooled one-shot color (OSC) cameras. It’s an ideal astronomy camera for experienced imagers and beginners alike.

Backlit Sensor for Maximum Quantum Efficiency

The back-illuminated 36mm x 24mm IMX410 CMOS sensor improves sensitivity and noise reduction – the key factors to enhancing image quality, while radically realigning their fundamental pixel structure from front-illumination to back-illumination.

With the conventional front-illumination structure used on some CMOS sensors, the metal wiring and transistors on the surface of the sensor’s light-sensitive area reduce the overall quantum efficiency. But the back-illuminated structure in the IMX410 increases the amount of light entering each pixel since the circuitry has been moved to the other side of the silicon sensor substrate. The result is a quantum efficiency that approaches 80%. The IMX410 also retains the advantages of CMOS image sensors such as low power consumption and high-speed operation.

Large Full-Well Depth capacity, Low Read-Out noise, and High Dynamic range

The full-well depth of the ASI2400MC Pro is 100ke, which is 132% greater than the ZWO ASI128MC Pro despite the similar pixel size of these two cameras. This means the ASI2400MC Pro comes with an ultra-high dynamic range of up to 14 stops, reducing the chance of overexposure and adding a richer color gradation.

When the gain value is set to 140, the HCG high gain mode is turned on and the readout noise drops as low as 1.1e while the dynamic range remains basically unchanged.

Zero Amp Glow

Traditional CMOS sensors produce a weak infrared light source during operation that’s often seen in the corner of uncalibrated images as the tell-tale signs of ‘amp glow’. The ASI2400MC Pro uses zero amp glow circuitry so you won’t have to worry about amp glow even when using high gain, long exposure imaging.

Anti-Dew Design

ASI2400MC Pro comes with a polyimide heater that greatly reduces dew formation on the camera window. The anti-dew heater draws about 5W and can be turned off in software to save power.

Two-Stage TEC Cooling for Ultra-Low Dark Current

ASI2400MC Pro incorporates two-stage thermoelectric cooling (TEC) that lowers the CMOS sensor temperature to as much as 35℃ below ambient which greatly reduces dark current and sensor noise, even with extended exposure times. The camera also uses dark current suppression technology that further reduces dark current noise. When it’s cooled to -20℃, the current noise can be as low as 0.00035e/s/pixel, which is completely negligible!

USB3.0 & 256M DDR3 Memory For Fast Data Transfer

The ASI2400MC Pro features a USB 3.0 data transmission interface and a built-in 256MB(2Gb) DDR3 cache to ensure stable and secure image transfer. Under long exposure, it effectively avoids frame dropping and greatly reduces amp glow caused by slow data transfer.
