      4.0 perfect fit for standard eyepiece barrels




      this adapters fits perfectly in the barrel of a 1.25" eyepiece with M28.5x0.6mm filter thread.
      it could use an extra mm of length (or two) of thread, to provide more strength to the assembly. but overall, it does the job, and it slides right through the holder tube, which is just what you need when you connect two barrels this way.

      Bottom Line: Would you recommend this item? Yes
