Product Description: Designed specifically for deep-sky imaging with Schmidt-Cassegrain and refractor telescopes, this Deluxe Off-Axis Guider (OAG) allows for simultaneous imaging and guiding through a single telescope. By using the same optical path for both imaging and guiding, it effectively eliminates common tracking issues such as differential flexure and mirror shift, resulting in highly accurate tracking and pinpoint stars. Key Features: Simultaneous Imaging and Guiding: Capture images and guide through the same telescope, ensuring both the imaging camera and autoguider see the same movement. Versatile Compatibility: Suitable for use with most imaging cameras, including DSLRs, and telescopes with sufficient inward focus travel. Precise Adjustments: Features a prism tilt adjustment with a captive thumbscrew and over 100 degrees of radial movement for easy guide star acquisition and centering. Focus Adjustment: Coarse and helical fine focus adjustments provide easy and accurate focusing. Eliminates Flexure Issues: By integrating the guiding and imaging paths, it avoids the flexure and inaccuracies that can occur with separate guide scopes. Guide Star Acquisition: A small adjustable prism redirects part of the primary telescope's light path to the eyepiece, facilitating the location and centering of suitable guide stars. Package Includes: 1 x Off-Axis Guider
