Featuring bright, wide-field optics and an adjustable dovetail bracket, it ensures easy installation and abundant guide stars for precise autoguiding. Engineered for use with the Orion StarShoot AutoGuider and similar CCD devices, it offers modern astro-imagers a space-saving, affordable solution for long-exposure imaging accuracy. ## Description The Orion-designed Mini 50mm Guide Scope is a complete and compact guide scope solution designed for use with the Orion StarShoot AutoGuider (sold separately) or similar small-chip CCD autoguider devices. The Orion Mini 50mm Guide Scope is ideal for guiding long-exposure astrophotographs with imaging telescopes up to 1500mm 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 auto-guiding 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 auto-guiding 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. ## Features - Compact mini guide scope designed for use with astrophotography telescopes up to 1500mm focal length - Mini 50mm guide scope with bright, wide-field optics puts numerous potential guide stars in view so you'll never have to search for one! - Adjustable-aim dovetail guide scope bracket installs on virtually any astrophotography telescope quickly and easily - Very small and compact autoguiding system adds hardly any weight to an astrophotography setup and can conveniently be stashed in an accessory case between uses - Designed for use with Orion StarShoot AutoGuider (sold separately) and other similar small-chip CCD autoguiders ## Product Details - **Brand:** Orion - **Model name:** OR-08891 - **Eye piece lens description:** None included - **Objective lens diameter:** 50 Millimeters - **Telescope mount description:** Equatorial Mount ## Images ![Orion 8891 Mini 50mm Guide Scope - Image 1](https://m.media-amazon.com/images/I/71BQ2mvoeuL.jpg) ![Orion 8891 Mini 50mm Guide Scope - Image 2](https://m.media-amazon.com/images/I/41EZpiD84SL.jpg) ![Orion 8891 Mini 50mm Guide Scope - Image 3](https://m.media-amazon.com/images/I/91c8L6+OY+L.jpg) ![Orion 8891 Mini 50mm Guide Scope - Image 4](https://m.media-amazon.com/images/I/41ekGo0gktL.jpg) ![Orion 8891 Mini 50mm Guide Scope - Image 5](https://m.media-amazon.com/images/I/71KMT7X36HL.jpg) ## Questions & Answers **Q: Does it accept a 1 1/4 eyepiece?** A: Yes, it can accept some 1.25" eyepieces.
