ZWO's ASI120MM-Mini 1.2-megapixel monochrome astronomy camera is perfect for planetary imaging or for autoguiding during long-exposure astrophotography. It incorporates a 1/3” CMOS sensor with 1280x960 resolution and 3.75-micron pixels. The ASI120MM-Mini offers peak QE of 75% and low read noise to give an excellent level of performance despite its compact size. The camera also includes an AR-coated window to maximize light transmission and protect the sensor. The camera weighs just 2.1oz and slips into a 1.25” focuser. It uses a small Type-C USB2.0 interface, the same type of connector used by many cell phones, and its ST4 port enables direct connection to the autoguiding port on a telescope mount.
