This is the USB 3.0 version of the asi120mm mono guide cam so it should be a bit more reliable than the usb 2.0 version. It has a 1.2 Mega Pixel 1280×960 sensor with 3.75 um pixels and is quite sensitive. It would make a great budget guide camera. The box includes all the cables (ST4 + USB3.0) as well as a 1.25" nose adapter, dust cap and all sky camera lens.
