FEATURED REVIEWS
Great OAG
Love it, well made, works great. Large prism and inside diameter. Easily rotates with adjustment screws on each side. Excellent adjustments for guide camera focus (Locking screws plus Helical adjustment).
Celestron Off Axis Guider
This OAG allows a wider viewing window for my guide camera to pick up guide stars, thereby allowing me to rack stars more accurately.
Take your astrophotography to the next level with the Celestron Off-Axis Guider, an indispensable tool for achieving the sharpest and most accurate celestial images. Designed for long focal length telescopes, this high-quality off-axis guider is engineered to provide precise guiding by using a prism to intercept a small portion of the telescope's focal plane. This innovative approach ensures that any movement detected by the guide star is identically reflected in the imaging camera, resulting in stellar astroimages with perfectly round stars.
Crafted from durable black anodized aluminum, the Celestron Off-Axis Guider is both compact and easy to use, making it a versatile addition to your astrophotography setup. It boasts a large 12.5mm adjustable prism, strategically positioned to capture brighter guide stars by moving closer to the center of the telescope's focal plane. This feature enhances the illumination of the autoguider sensor, ensuring that you can easily locate a guide star even from the far edges of the telescope's focal plane.
The guider's high-quality, fixed-orientation Helical focuser is a standout feature, offering smooth and precise focusing of the autoguider without altering the camera's orientation. This eliminates the common challenge of achieving simultaneous focus between the imaging camera and autoguider, saving you valuable time and effort.
Celestron's Off-Axis Guider comes complete with all necessary spacers and adapters, accommodating most common imaging configurations without the need for additional purchases. This includes compatibility with DSLR cameras, Nightscape CCD cameras, and more. The package includes a variety of adapters such as SCT/EdgeHD, female M48, female M42 (T-thread), male M48, male M42 (T-thread), and three T-thread spacers, ensuring a seamless integration with your existing equipment.
Additional Specifications:
- Helical Focuser Travel: 8mm, providing fine adjustments for optimal focus.
- Telescope Connection: M42 T-thread, M48, and SCT/EdgeHD, offering broad compatibility with various telescope models.
- Autoguider Connection: M42 T-thread, and standard 1.25" adapter, ensuring a secure and stable connection.

With a high customer rating of 4.5 out of 5 stars, the Celestron Off-Axis Guider is a testament to its reliability and performance. Choose this Celestron product for its reputation for producing top-tier optical equipment and experience the difference in your astrophotography pursuits.
