The ZWO ASI128MC Pro camera integrates the Sony IMX128 full-frame sensor (36 mm x 24 mm). This is among ZWO's first full frame cooled cameras. This camera has 6032 x 4032 pixels, and supports BIN2, BIN3, BIN4 mode. The pixel size is 5.97 μm x 5.97 μm. The camera provides 14bit ADC and its full well is 76000e.

The largest improvement between the "cool" and the "pro" versions is the addition of a 256MB DDR memory buffer for image downloads. This helps transfer data more stably and reduces or eliminates amp glow issues from the CMOS sensor. 


ASI128 Pro offers very good performance for astrophotography. Low read noise, high dynamic range, QE peak of 53%, AR protective window and much more.


IMX128 vs. KAI-11002

Compared with old full frame CCD such as  KAI-11002,  IMX128 has higher resolution, higher QE, lower read noise and faster FPS.

Unique Tilt Adapter

ASI128 Pro includes unique tilt adapter. Say goodbye to tilt problems forever !ASI094-tilt-adapter-3mm

USB 3.0 Port & USB2.0 HUB

USB 3.0 Port: can provide 5Gb bandwidth to let ASI128 Pro run at 7 fps (14bit, normal mode) or 10 fps (10bit, high speed mode)  at full resolution(24Mega).

ASI128 Pro camera has one full frame sensor, so the power consumption (650mA@5V) is much higher than other cameras. But USB3.0 can provide 1000mA current, so ASI128 Pro can run standalone under USB3.0 host, it doesn’t need an external power supply.

You need to connect the external 12v power supply if you connect the camera to USB 2.0 host which can only provide 500ma current.

We recommends 12V at 3A or more DC adapter for cooler power supply (2.1*5.5, center positive)

Battery from 9-15V is also suitable for cooler power supply

USB 2.0 HUB: can connect with various accessories, such as filter wheel, guide camera and electronic focuser, so you can manage your cable better with USB2.0 hub. There are 2 short 0.5m USB2.0 cable come with ASI128 Pro. the power of hub source from external power supply if you connect it. 

The ASI128 Pro has a 2 stage TEC cooling system to enable very deep cooling (-35℃ below ambient). You will need external power supply to power on the cooler. AC-DC power adapter is not included in this package (see related products).

The anti-dew heater can heat the protect window to avoid any dew problems, the heat power is around 6W and can be turned off in software to save power.
