To put it simply, a guide scope is a special optical device that’s designed to track your target star. It looks similar to a traditional finder scope. However, finder scopes are meant for manual tracking with the human eye. Guide scopes, on the other hand, work with a camera and computer to track your target automatically.

Guider scopes eliminate a lot of the guesswork. There are other types of guiding devices. But, guider scopes are more efficient and accessible than things like off-axis guiders or dual-chip cameras.

These scopes are very easy to use. They attach directly to the optical tube of your primary telescope. This ensures that the guide scope is always pointing in the same direction as the telescope. Once you connect the scope to an auto guider camera, computer, and star-tracking software, it handles all of the hard work.
