This adapter converts a 1.25" (31.75mm) diameter eyepiece holder (focuser) into a 2" (50.8mm) eyepiece holder, so that you can use larger 2" eyepieces on telescopes with standard 1.25" eyepiece holder.

You insert the smaller tube of this adapter into the 1.25" focuser of the telescope, and put 2" eyepiece into the larger 2" barrel of the adapter.


Main features:

  • Fit 1.25" (31.75mm) diameter telescope focuser, so that you can use 2" (50.8mm) eyepieces on the telescope. 

  • Dimensions:

    • Overall height: 60mm

    • The height of the section which goes into the 1.25" telescope focuser: 20mm

    • The height of the section that holds the 2" eyepiece: 37mm

  • Built with metal material and black anodized.

  • There is a brass compression ring inside the 2" barrel that clamps around the inserted eyepiece to prevent the eyepiece barrel from being scratched by the fixing screw.

  • There are internal threads (M28.5x0.75mm) inside the 1.25" tube for filter connection.
