  1. 2.4X Dakin Barlow for 1.25" eyepieces

    $210.00
    This Ralph Dakin doublet design is considered by many professional astronomers to be the Rolls-Royce of 1.25" Barlows. It has a magnification of 2.4x for non-repeating eyepiece powers.
  2. Tele Vue 2X Big Barlow for 2" eyepieces, with 1.25" eyepiece adapter

    $228.01
    This 2" 2x Clamp Ring Big Barlow can be used with any telescope using a 2" focuser. As it is only 4.5" long, it can also be used in most 2" star diagonals for 2x magnification.

    It can also be placed into a 2" focuser in front of a 2" star diagonal to give higher magnification than the nominal 2x. Some refractors might not have enough focuser travel to allow this directly, however. . . .
