Shed some weight from your astrophotography setup and still enjoy the benefits of autoguiding accuracy with the pint-sized Orion 30mm Ultra-Mini Guide Scope! Thanks to the availability of smaller, more sensitive autoguiding cameras, an excessively large guide scope is no longer necessary for many astrophotographers. Why not take advantage of these smaller autoguiding cameras and reduce the total weight of your imaging setup? It's easy with the extremely compact Orion 30mm Ultra-Mini Guide Scope. This pint-size performer 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. 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. A featherweight contender with a big performance punch, the Ultra-Mini Guide Scope weighs just 7.6 oz. Start enjoying the benefits of a lighter-weight imaging setup today! Guide scope and bracket only. Autoguider cameras sold separately.

Beginning level telescopes will show you countless lunar craters, Saturn's rings and a myriad of star clusters and nebulae! Referring to the manual is recommended.
Intermediate Level - These products offer higher performance and more advanced features than Level 1: Beginner models. They typically take a bit longer to learn and need some set-up or adjustments. But anyone with the slightest technical bent will have no problem getting familiar with these models. Referring to the manual is recommended.
Advanced Level - These products provide the best performance but may require more skill to master and appreciate. Optical instruments with this rating have exceptionally fine optics and mechanics. Some are easy to use but might be on the large or heavy side. Some are intended for specialized uses. These products will appeal to the more technically inclined. Referring to the manual is highly recommended.
For telescopes, the optical diameter (also known as aperture) is the size of a telescope's main light-collecting lens or primary mirror, measured in millimeters or inches. Telescopes with larger optical diameters collect more light, which leads to an increase in brightness and image resolution compared to smaller instruments.
For binoculars, the optical diameter (also known as objective lens diameter) is the size of each of the front-facing objective lenses of a binocular measured in millimeters. Binoculars with larger objective lenses collect more light, which increases image resolution and brightness. Binoculars with larger objective lenses are recommended for low light situations, and binoculars with at least 50mm or larger objective lenses are recommended for pleasing astronomical observations at night.
