This compact autoguiding setup is a perfect match for short focal-length, optically fast imaging telescopes. The 30mm Ultra-Mini 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. The Orion 30mm Ultra-Mini Guide Scope features C/CS-mount threads for secure, flexure-free attachment of the included StarShoot AutoGuider Pro Mono. 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.With an astonishing 74% peak quantum efficiency, the included StarShoot AutoGuider Pro will “guide” you to capturing better, cleaner, more precise astrophotos thanks to its high sensitivity, and it features a built-in ST-4 port. Its 1/3″ CMOS sensor resolution of 1280×960 (1.2MP) helps achieve delightfully accurate autoguiding. Included Orion AstroCap software is packed with capture features such as focus aids, histogram, exposure and gain settings, auto dark frame removal, and more. Software compatible with Windows XP, Vista, 7, 8 and 10 (32 bit and 64 bit). Includes ASCOM driver. A sturdy two-ring bracket for the Ultra-Mini Guide Scope with built-in 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. The multipurpose StarShoot AutoGuider Pro comes with a host of useful items including a 1.25″ nosepiece threaded for use with like-sized filters, a parfocal ring to aid in matching eyepiece focus to camera focus, USB cable, secure RJ-11 autoguider cable, and a nice foam-lined tin case for safe storage and transport.
