DDR3 Memory Buffer

The ASI128 Pro camera includes one 256MB DDR3 memory buffer to help make data transfer more stable and remove the amp-glow issue which is caused by the slow speed data transfer during reading out under a USB2.0 Port.

ASI128 Astrophotography Performance

The 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 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 a unique tilt adapter. Say goodbye to tilt problems forever!

USB3.0 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).

The 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 recommend 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 cables better with the USB2.0 hub. There are 2 short 0.5m USB2.0 cable supplied with ASI128 Pro. the power of the hub is sourced from an external power supply if you connect it.

Cooling & Anti-Dew Heater

ASI128 Pro has a 2 stage TEC cooling system to enable very deep cooling (-35℃ below ambient). An external power supply is required to power the cooler. An AC-DC power adapter is not included.

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