Orion Mini 50mm Guide Scope

The Orion-designed Mini 50 mm Guide Scope is a complete and compact guide scope 50 mm (1.97-inches) aperture - solution designed for use with the Orion StarShoot AutoGuider (sold separately #OR-52064) or similar small-chip CCD autoguider devices. The Orion Mini 50 mm Guide Scope is ideal for guiding long-exposure astrophotographs with imaging telescopes up to 1500 mm in focal length. Thanks to the high level of guiding accuracy offered by modern autoguider devices such as the Orion StarShoot AutoGuider, astro-imagers of today can use guide scopes with much shorter focal lengths and smaller apertures compared to the large, bulky models used in the past. Using a more optically "fast" refractor as a guide scope can save astro-imagers time, space, and money, but will still provide the unrivaled accuracy that only autoguiding can bring to long-exposure astrophotographs. Although modern dedicated autoguider devices allow small, optically fast guide scopes to be used with excellent results, t
