iOptron iGuider mini Guiding Scope

Compact. Sharp. Reliable.

With a 30mm aperture and 120mm focal length, the iGuider Mini provides a crisp, wide field of view that makes it easy to lock onto guide stars—even in crowded or faint regions of the sky. The fast f/4 focal ratio keeps exposures short and guiding responsive, ensuring smooth correction during long exposure runs.

The optical tube is fitted with precision-ground achromatic elements, fully coated to reduce ghosting and maximize light throughput.

Designed for 1.25" Guide Cameras

The back of the scope accepts standard 1.25" barrel autoguiders, including the iOptron iGuider and other popular CMOS guide cameras. The slip-fit connection makes setup fast, secure, and repeatable—no threading or adapter rings required.

Easy Mounting with Finder-Style Dovetail

The iGuider Mini comes pre-mounted on a 19mm-wide dovetail foot, compatible with many finder scope brackets and saddle clamps. On select iOptron mounts (like the CEM26, GEM28, CEM40, and GEM45), it installs directly to the mount housing without the need for adapter plates—keeping your setup streamlined and well-balanced.

Lightweight and Travel-Friendly

Weighing in at just under half a pound, the iGuider Mini is perfect for imaging rigs where weight and space are at a premium. Despite its compact size, its performance and precision easily keep up with larger guide scopes, making it an ideal match for wide-field refractors or lightweight tracking systems.

Observing Tip

If you're chasing tighter stars and cleaner subs, guiding is the upgrade that makes it happen—and pairing this scope with a 1.25" guide camera is an easy win. For best results, align the guide scope parallel with your imaging OTA, and use short exposure times in your guiding software for real-time corrections with minimal lag.
