This camera has 6032 x 4032 pixels, and supports BIN2, BIN3, BIN4 mode. The pixel size is 5.97 μm x 5.97 μm.  This camera provides 14bit ADC and its full well is 76000e. It has larger pixels that the ASI094MC Pro providing greater well depth making it a better match for longer focal length telescopes.

DDR Memory Buffer

New with the introduction of the ASI128 Pro camera is an onboard 256MB DDR3 memory buffer. It ensures more stable data transfer and eliminates any amp-glow encountered with slower USB2.0 port during image read out.

DDR memory buffer is the main difference between ASI “Cooled”  series and “Pro” series cameras.

Astrophotography Performance

The ZWO ASI128MC Pro offers very good performance for astrophotography. Important factors include, low read noise, high dynamic range and peak QE of 53%.

Unique Tilt Adapter

The ASI128MC includes a unique tilt adapter. The larger size of full frame sensors makes it crucial to be able to eliminate tilt at the focal plane. ZWO have incorporated this ability with a push pull tilt adjuster built into the front of the camera.

USB 3.0 Port & USB2.0 HUB

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

The ASI128 full frame sensor requires 650mA@5V which is much higher than other cameras in the ZWO lineup. USB3.0 can provide 1000mA current, so the ASI128 can run standalone under USB3.0 host without the need for an external power supply (without cooling).

If you connect the camera to USB 2.0 host, which can only provide 500ma current, you will need an external 12V power supply just for camera operation even without cooling.

A 12V (3A or more) DC adapter for necessary 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: allows connection of various accessories, such as filter wheel, guide camera and electronic focuser. The USB2.0 hub allows better cable management. There are 2 short 0.5m USB2.0 cables supplied with the ASI128. The USB2.0 hub is powered from your external power when connected

Cooling and Anti-Dew Heater

The new ZWO ASI128 Pro has 2 stage TEC cooling to enable very deep cooling (-35℃ below ambient). An external power supply is required to power the cooler (An AC-DC power supply is not included with the package, you can find a suitable one here).

A dew heater is built into the camera around the sensor chamber window. It has a heating power of 6W and can be turned on using your camera control software. In warmer/less humid conditions it can also be turned off to conserve power.
