The ZWO ASI2400MC Pro is a full frame, color astro imaging camera with a Sony IMX410 back-illuminated sensor.
The First CMOS Astro Camera with the Sony IMX410 Sensor
ASI2400MC Pro uses Sony’s latest back-illuminated IMX410 full-frame format 14-bit ADC sensor. This 24MP camera, with it's large pixel size of 5.94 microns, can accommodate a super large well depth of 100ke.
Full Frame OSC Camera
The ASI2400MC Pro uses a full-frame format, the sensor length and width are 36 mm by 24 mm and the diagonal is 43.3 mm. For now, there only has the OSC version, which is very suitable for beginner astrophotography.
IMX410 Backlit Sensor
The back-illuminated 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.
Ultra-low readout noise (1.1e) and zero amp glow.
A back-illuminated structure minimizes the degradation of sensitivity to optical angle response, while also increasing the amount of light that enters each pixel due to the lack of obstacles such as metal wiring and transistors that have been moved to the reverse of the silicon substrate.
Camera Performance:
Large well depth capacity, low read-out noise and high dynamic range.
Though these two full frame cameras share very similar pixel sizes (ASI2400MC Pro 5.94 um vs ASI128MC Pro 5.96 um), the well depth capacity of ASI2400MC Pro is 100ke, which is 132% of the ASI128MC Pro. Additionally, the ASI2400MC Pro comes with ultra-high a dynamic range up to 14 stops, lending the overexposure probability will be reduced, and receiving richer color gradation.
When the gain value is 140, the magical HCG (high gain mode) is turned on, the readout noise is greatly reduced (as low as 1.1e), and the dynamic range is essentially unchanged.
Zero Amp Glow
Traditional CMOS sensors produce a weak infrared light source during operation quite often seen in the corner of uncalibrated images as the tell tale signs of ‘amp glow’. As the ASI2400MC Pro uses zero amp glow circuitry, you won’t have to worry about amp glow even when using high gain, long exposure imaging.
- Left image: Other CMOS sensors with amp glow – exposure 300 second exposure.
- Right image: ASI2400 frame with no amp glow – exposure 300 seconds.
Anti-Dew
Polyimide heater to help you avoid any dew problems. It fits the protective window and will heat it to avoid the usual problems with dew. power usage is around 5W and can be turned-off with the software to save power.
Peak QE
ZWO expects that the QE peak value of the ASI2400MC Pro is above 80%, before testing.
Two-Stage TEC Cooling: Ultra-Low Dark Current
ASI2400MC Pro uses two stage TEC cooling that can lower the CMOS sensor temperature to more that 35c below ambient, which can greatly reduce dark current generation and sensor noise even with extended exposure times.
The unique dark current suppression technology can even further reduce dark current noise. When it’s cooled to -20℃, the current noise can be as low as 0.00035e/s/pix, which is completely negligible!
Note：ASI2400 Pro camera requires 1A current from the USB, if your PC can not provide enough current, please use an external 12V power supply to power the camera.
USB3.0 & 256M DDR3 Memory
USB 3.0 transmission interface and built-in 256MB(2Gb) DDR3 cache ensure stable and secure data transmission. Under long exposure, it effectively avoids frame dropping and greatly reduces the glow effect caused by slow reading speed.
