ZWO ASI128MC Pro (Color)

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.


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.
