50mm Guidescope with Helical Focuser
This is a generic 50mm guide scope for autoguiding your equatorial mount for astrophotography.
The scope has a separate focus mechanism making it easy to get a sharp guide star. It has a focal length of 162mm and a fast ratio of f/3.2, meaning you will have a good choice of stars in the field to choose from.
Aiming is simple, and the six mounting screws provide a secure mount so the scope does not shift during the night.
Attaches on the standard foot used for finderscopes on most saxon, Sky-Watcher, and Orion telescopes (Celestron scopes require a separate adapter).
