This popular eyepiece adapter allows 2" eyepieces, diagonals, and other accessories to be used in 1.25" focusers, diagonals and barlows. Precision machined from black anodized aluminum, this premium adapter includes a brass compression ring that restrains the eyepiece and prevents marring of the eyepiece barrel by the metal set-screw. The lower barrel is threaded to accept standard 1.25" filters.
Total height = 2.35" (59.8mm). Height of upper 2" barrel = 1.53" (38.8mm). Height of lower 1.25" barrel = 0.8" (21mm). Weight = 3.1oz.
Please note that the use of extension/conversion tubes such as this item requires additional in-focus travel. If your eyepiece is fully seated in the 2" upper barrel, then you will require 1.53" of additional in-focus travel. If your eyepiece does not fully seat in the barrel and extends out, then you will require additional in-focus travel by the amount the eyepiece extends out. As in the case of barlows, focal reducers, diagonals, and other accessories, your telescope may or may not be able to accommodate this additional travel requirement, so you may not be able to reach focus with all eyepieces and configurations. That is technically a limitation of the mechanical design of the telescope and not a shortcoming of the product itself.
Also, it is possible that your view through some 2" eyepieces might be vignetted when used with this adapter because of the smaller 1.25" barrel in the light path. This will depend on your telescope and eyepiece combination and cannot be predicted in advance. However, many customers have successfully used this adapter with many 2" eyepieces, especially in the Meade ETX line of telescopes.
