  9. Tele Vue 55mm Plössl

    $255.01
    If you have a 2" focuser on your f/8 and longer focal ratio telescope, this 2" eyepiece will give you the widest possible field of view - even wider than a 31mm Nagler, but at less than 40% the cost . . .
  10. 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. . . .
