Product Details

  • The F50 Guidescope w/Straight-Through Helical Focuser by Stellarvue:

    Stellarvue's 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 M42 x .75-inch threaded T-ring or 1.25-inch nosepiece rather than a slip-fit diagonal.

    The F50G includes 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-inch standard or reticle eyepiece of your choice. 

    The 1.25-inch 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.
