Product Description

ASI2400MC Pro-2

The First CMOS Astro Camera Which Adopts Sony IMX410 Sensor

ASI2400MC Pro uses Sony’s latest back-illuminated IMX410 full-frame format 14-bit ADC sensor. It is a 24MP camera with a big pixel size of 5.94um that can accommodate a super large well depth of 100ke.

With the ultra-low readout noise of 1.1e and amazing zero amp-glow, the ASI2400MC Pro is born to be another great innovation of ZWO in the field of full-frame cooled OSC astro cameras.

Full Frame OSC Camera

The ASI2400MC Pro uses full-frame format, the sensor length and width are 36mm * 24mm and the diagonal is 43.3mm. For now, it 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. It has retained the advantages of CMOS image sensors such as low power consumption and high-speed operation.

With a conventional front-illumination structure, the metal wiring and transistors on the surface of the silicon substrate that form the sensor’s light-sensitive area (photo-diode) impede photon gathering carried out by the on-chip lens. 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 cameras share very similar pixel sizes (5.94um vs 5.96um), the well depth capacity of ASI2400MC Pro is 100ke, which is 132% of another full frame ASI camera ASI128MC Pro, so ASI2400MC Pro comes with ultra-high a dynamic range up to 14stops. Upon that, overexposure probability will be reduced, with richer color gradation gained.

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 basically 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.

Anti-Dew

ASI2400MC Pro comes with the polyimide heater that can avoid any dew problems.

The anti-dew heater which completely fit the protective window will heat it to avoid any dew problems.

The heat anti-dew heater power is around 5W and can be turn off in software to save power.

QE Value

We suppose that the QE peak value of the ASI2400MC Pro is above 80%.

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. (Voltage range: 11~15V. 12V recommended).

USB3.0 & 256M DDR3 Memory

The ASI2400MC Pro is equipped with a USB 3.0 transmission interface and a built-in 256MB(2Gb) DDR3 cache to 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.
