Stellarvue F50 Guidescope w/Straight-Through Helical Focuser
The Stellarvue F50G Guidescope has a focal length of 210 mm and sports an objective that is finished off with a broadband FMC coating for beautiful clarity and contrast. The F50 Guidescope is similar to the Stellarvue 50 mm finderscope, except it is designed to accept an M42x.75 threaded t-ring or 1.25” nosepiece rather than a slip-fit diagonal.
The Stellarvue F50G comes with a 10 mm threaded extension, which allows you to convert the optical tube into a straight-through finder. Simply install the extension between the guidescope’s helical focuser and the main tube and then add the 1.25” standard or reticle eyepiece of your choice. See the photograph to the left for a guide regarding the installation of the extension.
The 1.25” non-rotating helical focuser is lubricated to give you a smooth focusing experience. The F50G will fit Stellarvue’s standard 50 mm ring systems, creating a nice guiding system for your refractor or other telescope.
