Product Details

  • This Non-Rotating Helical Focuser is used to convert a Stellarvue 50 mm right angle finderscope into a 50 mm straight-through finderscope. Now the image on your finderscope will be inverted and your finderscope can now be used as a guidescope. 

    It is as easy to use as simply unthreading the right-angle prism assembly from the main tube and replace it with the Helical Focuser.

    The SV-F050HNR features a 1.25-inch non-rotating helical focuser and includes a 10 mm (STE52) extension. 

    This is the same focuser that is used on the Stellarvue SV-F050G, so it can also be used there as a guidescope as well.

    The focuser has a standard 1.25-inch compression ring unit with an external M42 x .75 T-thread. So you can either use a guide camera's T-thread or a 1.25-inch nosepiece.
