ZWO Mini Guidescope 30 mm f/4

The ZWO Mini Guidescope 30 mm is the standard for those who are serious about autoguiding on a lightweight and portable setup. This compact viewfinder fits directly into standard viewfinder shoes from the likes of Sky-Watcher, Omegon, GSO and Celestron, and its low weight of 384 grams makes it perfect for mobile astrophotographers.

With a focal length of 150 mm and an aperture ratio of f/5, it offers a bright and wide field of view, ideal for star tracking with mini-camera models such as the ZWO ASI120MM Mini. The helical focuser allows you to focus accurately - without rotating the camera - which is crucial for consistent tracking work.

The guidescope accepts both T2 connectors and 1.25” accessories via an adapter, allowing almost any autoguider to be mounted directly. The included mounting ring with knurled screws ensures a solid, slide-free mount.

What makes this guidescope indispensable?
- Perfect compatibility with mini guide cameras
- Compact and light: only 384 grams
