Product Description
Bigger than bigger
The ASI128MC Pro camera integrates the Sony IMX128 full-frame sensor (36 mm x 24 mm). It is ZWO’s full-frame cooled 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.
DDR Memory Buffer
ASI128 Pro camera includes a 256MB DDR3 memory buffer to help improve data transfer reliability. Additionally, the use of a memory buffer minimizes amp-glow, which is caused by the slow transfer speeds when the camera is used with a USB 2.0 port.
DDR memory buffer is the main difference between ASI “Cool” and “Pro” cameras.

ASI128 Pro offers very good performance for astrophotography. Low read noise, high dynamic range, QE peak 53%, AR protective window and much more.
IMX128 vs. KAI-11002
Compared to old fill frame CCD sensors such as the KAI-11002, the IMX128 has higher resolution, higher QE with lower read noise and faster FPS.
Unique Tilt Adapter
ASI128 Pro includes unique tilt adapter. Say goodbye to tilt problems forever !
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 external 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.
Cooling and Anti-Dew Heater
ASI128 Pro has a two-stage TEC cooling system that allows deep cooling (30°C-35°C below ambient). You will need an external power supply to power the cooler. An AC-DC power adapter is not included in this package, however you can order one from here.
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.
Recommended cooler power supply: 12V @ 3-5A (or more) DC adapter (2.1×5.5mm, center pole positive). Also suitable: DC battery with 9-15V.
The anti-dew heater can heat the protect window to avoid any dew problem happens, the heat power is around 3.6W and can be turn off in software to save power.

Are there plans to make a mono version of the ASI128 Pro cool? If so is there a estimated release date. Are there any plans on making a 9 micron pixel mono cooled large format camera?
Thank you
