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.

    Stellarvue F50G Guidescope Specifications:
    • Aperture: 50 mm
    • Focal Length: 210 mm
    • Focuser: 1.25-inch non-rotating Helical
    • Weight: 18 ounces
    • Diameter of Tube: 54.5 mm
    • Diameter of Dew Shield: 58 mm
    • Tube Length: 9.25-inch to 9.5-inch

works wonderfully but took 3 months to get here

Not sure why Stellarvue has such a hard time producing products. 3months wait is a bit excessive for a budget guide scope. I've been using a POS 99.99 guide scope from Oxixn and hated it. But used it for 3 years. Having some guiding problems I reworked things and swapped over to this guide scope. STARS ARE POINTS not smears now. I got total RMS arcs of 0.17. EAT THAT!

Works like a charm

The scope has preformed as expected. No issues at all. I bought this as a guide scope for my C11 and with the idea to put it in the bracket of the original finder scope. The fit is not perfect but it’s acceptable.

Great Guidescope

I had an old Stellarvue 50mm without the helical focuser and M42 threads. Moden guide cameras would not come to focus. This modelworks well and is outstanding
