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

You insert the 2" tube into the telescope's focuser, then put the 1.25" eyepiece into the barrel of the adapter.

Main features:

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

  • Overall height of the adapter: 28mm

  • The height of the section which goes into the 2" telescope focuser: 18mm

  • The height of the section that holds the 1.25" eyepiece: 20mm

  • Built with metal material and black anodized.

  • There is a brass compression ring that clamps around the inserted eyepiece or accessory. This will prevent the eyepiece barrel from being scratched by the fixing screw.
