Off-axis guide for telescopes

An off-axis guider is the ideal tool for improving the accuracy of your astrophotography sessions. An off-axis guider sends an image to your guide camera using an internal prism that collects light from outside the telescope's axis. This automatically corrects for telescope movement during long exposures and keeps your images perfectly sharp.

This method is considered the most accurate for guiding because it eliminates errors related to flexure or misalignment between a guide scope and the main telescope. It is particularly effective for deep sky objects and long exposures, where every small correction counts to capture subtle details of galaxies, nebulae, and star clusters.

The off-axis guider easily installs between your telescope and main camera and works with most astrophotography setups. It provides precise and consistent tracking control, ensuring sharp, perfectly aligned images. It can be used with telescope guiding accessories or guide rings to create a complete and effective setup.

For astronomers who prefer an alternative method, on-axis guiders offer direct guidance on the telescope's optical axis and can be used depending on the type of instrument and desired astrophotography style.

Explore our selection of off-axis guiders to optimize your acquisitions and achieve professional results.
