Orion 30mm Ultra-Mini Guide Scope

The Orion 30mm Ultra-Mini Guide Scope packs impressive optics into a super small guide scope. This makes the Ultra-Mini Guide Scope ideal for short focal-length, optically fast imaging telescopes. The guide scope's multi-coated, f/4.3 optics provides a very wide field of view so you'll always have plenty of options when selecting guide stars.

Designed specifically for use with the Orion StarShoot AutoGuider Pro Mono Astrophotography Camera, Orion StarShoot All-In-One Astrophotography Camera, and similar eyepiece-sized autoguider cameras, the Orion 30mm Ultra-Mini Guide Scope features C/CS-mount threads for secure, flexure-free camera attachment. The front housing of the Ultra-Mini Guide scope doubles as a precise helical focuser with etched hash-mark scale for easy and repeatable focusing. After an initial helical focus adjustment to match your autoguider device, a handy thumbscrew allows the focus position to be locked so you'll never have to fuss with focus in the field. If you wish to change autoguider devices, simply loosen the thumbscrew lock and adjust focus of the Ultra-Mini Guide Scope to match your preferred device.

A sturdy two-ring bracket with a dovetail foot is included which is designed to fit the dovetail base found on Orion telescopes and many other brands. A threaded 1/4"-20 socket on the underside of the dovetail foot allows direct attachment to a universal plate. At just 4.7" long, the Orion 30mm Ultra-Mini Guide Scope won't take up a lot of space when you're packing up imaging gear for astrophotographic adventures. For convenient storage and transport, a die-cut foam lined tin case is included.
