The ZWO Mini Guidescope 30 mm is the standard for those serious about autoguiding with a light and portable setup. This compact finder fits directly into standard finder shoes from Sky-Watcher, Omegon, GSO, and Celestron, and with its low weight of 384 grams, it’s perfectly suited for mobile astrophotographers.
With a focal length of 150 mm and an aperture ratio of f/5, it provides a bright and wide field of view, ideal for tracking stars with mini camera models like the ZWO ASI120MM Mini. Thanks to the helical focuser, you can focus precisely — without camera rotation — which is crucial for consistent tracking work.
The guidescope accepts both T2 connections and 1.25″ accessories via an adapter, allowing almost any autoguider to be mounted directly. The included mounting ring with knurled screws ensures solid, slip-free attachment.
