The ZWO ASI 290MM Mini is a professional guiding camera with small pixels for more precise guiding with short focal length scopes.
The ZWO ASI 290MM Mini contains the Sony IMX290 monochrome sensor which has a diagonal of 6.46mm and a resolution of 2.11 MPx.
The sensor has a high QE that reaches over 80% at 600 Nm.

The ASI 290MM Mini uses a USB 2.0 type C port and it is also equipped with a ST4 port as guiding alternative.
Compared to the classic ASI 290MM camera, the ASI 290MM Mini is lighter and has a shorter back focus, making it ideal for off-axis guiders or finderscopes.
