About this item
Product details
The Celestron Off-Axis Guider is an essential astroimaging accessory for long focal length telescopes, providing the most accurate guiding possible. It uses a prism to intercept a portion of the telescope's focal plane, allowing the guide star to be tracked and any movement to be corrected, resulting in better astroimages with pinpoint round stars. The Off-Axis Guider addresses common challenges by offering a large adjustable prism for brighter guide stars, a high-quality Helical focuser for smooth and accurate focus, and all the necessary adapters for a variety of imaging configurations, including DSLR and CCD cameras.
- The Off-Axis Guider is an essential astroimaging accessory for long focal length telescopes that require the most accurate guiding possible.
- The Celestron Off-Axis Guider uses a prism to intercept a small portion of the telescope's focal plane (outside the field of view of the main imaging camera) to locate a guide star.
- Any movement seen by the guide star will be the exact same movement seen by the imaging camera, correcting for tracking errors, as well as opto-mechanical errors or flexure.
- The large 12.5 mm prism can be adjusted to move closer to the center of the telescope's focal plane, resulting in brighter guide stars.
- The high-quality, fixed-orientation Helical focuser provides extremely smooth and accurate focus of the autoguider without changing the autoguider camera orientation.
- Includes all the needed spacers and adapters for most common imaging configurations, including DSLR cameras, Nightscape CCD cameras, and more.
