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, there is an unfortunate scarcity of quality offerings available. That is, until now. Our new Orion Mini 50mm Guide Scope brings autoguiding into the realm of affordability for any astro-imager, and brings the guide scope to a position that was previously occupied by a telescope finder scope.

Consisting of a 50 mm aperture, 162 mm focal length (f/3.2) achromatic refractor guide scope, an adjustable dovetail guide scope bracket, an 1.25-inch aluminum parfocal ring, a dovetail mounting base, and an adapter plate, the Orion Mini 50mm Guide Scope makes it easy for any astro-imager to enjoy the precision of autoguiding in their images. All this pint-sized setup requires is a StarShoot AutoGuider (sold separately) or similar small-chip CCD autoguider and it's ready for "Night. Camera. Action!" The guide scope bracket fits into the standard Orion dovetail finderscope base found on most Orion telescopes. If your imaging scope doesn't feature a dovetail base or has one already occupied by an often-used finder, the included dovetail base and attachment hardware lets you attach the Mini 50 mm Guide Scope to any optical tube.

Alternatively, the included adapter plate can be used to attach the dovetail base and Mini 50 mm Guide Scope to any standard dovetail plate, or side-by-side plate if preferred. The featherweight guidescope tips the scales at a mere 16 oz., and has been designed for use with imaging telescopes measuring up to 1500 mm in focal length. This one-pound wonder Mini 50 mm Guide Scope features fully multi-coated optics and a focus-adjusting front ring with locking collar. The included parfocal ring makes it easy to repeat autoguiding performance night to night, by letting you set the ideal focus position of the autoguider. Find out how easy and affordable it can be to add autoguiding precision to your images today with the new Orion Mini 50mm Guide Scope!
