ZWO Guide Cameras

ZWO guide cameras track a guide star and send corrections to the mount through PHD2, an ASIAIR or an ST-4 port, keeping stars round in long exposures. The ASI Mini series, including the ASI120MM, ASI220MM and ASI174MM Mini, has a slim 1.25" body made for guide scopes and OAGs.

Standard uncooled cameras such as the ASI120MM-S, ASI178MM, ASI290MM and ASI462MM guide equally well and can double as planetary cameras.
