ZWO ASI120MM Mini Monochrome Imaging Camera

This ASI120MM Mini Camera from ZWO incorporates a 1/3" AR0130CS monochrome sensor with 3.75 µm square pixels in a 1280 x 960 pixel array. It offers 12-Bit ADC with a peak QE of approximately 75%.

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.

ASIair Pro Camera Control (sold separately)

There is a wireless camera control solution available for this camera, and it's called the ZWO ASIair Pro. This small wireless module allows you to focus, take images, make adjustments with your smartphone or tablet, and even do plate solving and computerized mount control with the built-in SkySafari bridge. If you'd like to add an ASIair Pro to your camera order, you can find it in the suggested accessories section.
