ASI128MC Pro camera integrates Sony IMX128 full-frame sensor (36 mm x 24 mm). It is ZWO full-frame cooled camera. 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.
DDR Memory Buffer
ASI128 Pro camera includes one 256MB DDR3 memory buffer to help data transfer more stable and no amp-glow issue which is caused by the slow speed data transfer during reading out under USB2.0 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.
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.
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.
Unique Tilt Adapter
ASI128 Pro includes unique tilt adapter. Say goodbye to tilt problems forever !
Cooling and Anti-Dew Heater
ASI128 Pro has 2 stage TEC cooling system to enable very deep cooling (-35℃ below ambient). you need external power supply to power on the cooler. AC-DC power adapter is not included in this package, you can order from here.
The anti-dew heater can heat the protect window to avoid any dew problem happens, the heat power is around 6W and can be turn off in software to save power.
