Add auto guiding accuracy to any astrophotography setup with the affordable Orion Thin Off-Axis Guider. This versatile accessory lets you image and guide through a single telescope without the need for a separate guide scope! Its thin, 10.5mm profile makes the Orion Thin Off-Axis Guider a unique and versatile offering to today's astrophotographers. It's ideal for use with Newtonian reflector telescopes which have limited back focus travel. Until now, astrophotographers who used Newtonian reflector telescopes had to use a separate guide scope to add auto guiding accuracy to their images. With the convenient Thin Off-Axis Guider, you can guide and capture astrophotos using one telescope - no guide scope required! Using the Thin Off-Axis Guider for Astrophotography will help you save time and reduce the weight and bulk of your imaging system while eliminating pesky tracking errors. Designed for use with the Orion Star Shoot Auto Guider (sold separately) and similar small-chip auto guiding devices, the Orion Thin Off-Axis Guider features lateral adjustment capability which can effectively double the prism's width for increased versatility. This handy astrophotography accessory comes with a host of useful adapters including a C-mount to T-threads adapter, Canon DSLR bayonet adapter, Camera T-adapter, ultra-thin M48 male to T-adapter female adapter, 3mm Coma-Corrector spacer, 18mm spacer, and a 2 inch nosepiece. Thanks to these included adapters, the Orion Thin Off-Axis Guider for Astrophotography will work with many imaging systems right out of the box. Whether you use a Newtonian astrograph, Schmidt-Cassegrain, or other telescope for your astrophotographic pursuits, get the Orion Thin Off-Axis Guider for Astrophotography and start enjoying increased accuracy in your photos of the cosmos!

Compensates for any existing flexures that may interfere with accurate guiding and tracking.

Lets you guide and capture astrophotos simultaneously through one telescope. No guide scope required!. Delightfully thin off-axis guider ideal for use with Newtonian reflector telescopes and DSLR cameras.
