The ZWO ASI 290MM is a professional monochrome planetary camera with extra small pixels and a staggering fast frame rate up to 170 fps and over.

The ZWO ASI 290MM contains the Sony IMX290LQR or IMX291LQR CMOS monochrome sensor which has a diagonal of 6.46mm and a resolution of 2.12 MPx.
The back illuminated sensor allows to reach a QE up to 80% with a sensitivity across all the visible light as well as in infrared and part of the ultraviolet between 300 Nm and 400 Nm.
The USB 3.0 Port provides 5Gbps bandwidth and lets the camera run at 82.2fps (12bit, normal mode) or 170fps (10bit, high speed mode) at full resolution (2.1Mega). For planets that cover a small area of the sensor, the fps can be increased to over 250 per second by selecting a small ROI (region of interest). Frame rate can be limited by the power of the computer and the writing speed of your hard disk. For higher performance it is suggested to use Solid State Drives.
This camera is equipped with a ST4 port as guiding alternative.
