Similar to a finder scope, these guide scopes feature a non-rotating helical focuser making it easier to focus the camera.

These guide scopes have been very popular for guiding a refractor. Either 50 mm guide scope fits on our dual ring systems.

These guide scopes may be used as a straight through finderscope with the addition of a 1.25” reticle eyepiece. They will not work with a diagonal however as they will not reach focus.
