Astrophotography Performance
With low read noise, high dynamic range, 75% peak QE, AR protective window, and much more, the ZWO ASI120 Monochrome Mini provides exceptional performance for planetary imaging and guiding.
ASI120 Mini vs. ASI120MM-S
In comparison with the larger ASI120MM-S camera, the ASI120MM Mini is lighter, more compact, and is capable of reaching focus at the same position as the eyepiece.
USB 2.0 and ST4 Ports
ZWO Mini cameras feature one USB2.0 type C port. Type C ports are optimally suited for mobile phones as the positive and negative sides of the adapter are not important. The ST4 port connects the ASI120 Mini directly to the mount’s autoguiding port.
