Astrophotography Performance ASI290MM offers very good performance for astrophotography. Low read noise, high dynamic range, QE peak about 80 Percent , AR protective window and much more.  
High QE.Relative QE Curve, we estimate the Peak Value is about 80%.
USB 3.0 Port: can provide 5Gb bandwidth to let ASI290 run at 82.2fps (12bit, normal mode) or 170 fps (10bit, high speed mode) at full resolution(2.1Mega). ST4 Port: can be used connect with auto guide port of mount, for guiding.
