The ZWO ASI 120MC is a valuable compact guiding and planetary camera.

The ZWO ASI 120MC contains the AR0130CS CMOS monochrome sensor which has a diagonal of 6.00mm and a resolution of 1.22 MPx.
The sensor has a high QE that reaches almost 80% at 540 Nm. This allows to reduce the exposure in high resolution imaging and displays more stars for guiding.
The USB 3.0 Port provides 5Gbps and lets the camera run at 60fps at full resolution. For planets that cover a small area of the sensor, the fps can be increased 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.
