Precision Astroimaging GuidingCapture Pinpoint Stars Every Exposure
The Celestron Deluxe Off Axis Guider is an essential astroimaging accessory designed for long focal length telescopes requiring unmatched tracking accuracy. By tapping into the telescope's focal plane with a large prism, the Celestron Deluxe Off Axis Guider eliminates flexure and opto-mechanical tracking errors for superior deep-sky astrophotography. Upgrading your setup with this advanced autoguider solution ensures long-exposure astroimages with pinpoint round stars.
Advanced Deep-Sky Imaging SolutionConquer Flexure and Finding Guide Stars
Traditional guide scopes often suffer from differential flexure and difficulty locating guide stars, but the Celestron Deluxe Off Axis Guider solves these challenges with innovative design. Equipped with a large 12.5mm multi-coated prism, it captures maximum light outside the main field of view to brightly illuminate your autoguider sensor. A built-in fixed-orientation helical focuser enables smooth, highly accurate focusing without rotating the guide camera, while the wide 48mm clear aperture prevents vignetting on full-frame sensors. Perfect for Schmidt-Cassegrain and EdgeHD telescopes, this complete kit includes all necessary adapters for seamlessly connecting DSLR cameras, CCD setups, and popular astrophotography equipment.

Frequently Asked QuestionsEverything you need to know
What is the primary benefit of using the Celestron Deluxe Off Axis Guider over a separate guide scope?
The Celestron Deluxe Off Axis Guider eliminates differential flexure and opto-mechanical tracking errors by using the telescope's main focal plane to locate guide stars, resulting in pinpoint round stars during long exposures.
Will the Celestron Deluxe Off Axis Guider work with full-frame camera sensors?
Yes, the Celestron Deluxe Off Axis Guider features a generous 48mm clear aperture designed to support full-frame imaging sensors without causing vignetting.
What adapters are included with the Celestron Deluxe Off Axis Guider?
The Celestron Deluxe Off Axis Guider includes adapters for SCT/EdgeHD telescopes, female M48, female M42 (T-thread), male M48, male M42 (T-thread), and three T-thread spacers for proper spacing.
How does the helical focuser on the Celestron Deluxe Off Axis Guider operate?
The Celestron Deluxe Off Axis Guider uses a fixed-orientation helical focuser that enables precise focus adjustments for your autoguider camera without twisting or changing the camera's orientation.
