ZWO ASI Mini Guide Cameras

ZWO ASI Mini guide cameras are compact mono cameras with a slim 1.25" body that slides into a guide scope or off-axis guider like an eyepiece. They connect by USB to PHD2 or an ASIAIR and also offer an ST-4 guide port.

The line includes the ASI120MM Mini, a common first guide camera, the ASI220MM Mini and ASI290MM Mini for higher sensitivity, and the ASI174MM Mini, whose larger sensor helps find guide stars through an OAG.
