    If you need a very high quality 2x Barlow for 2" eyepieces, look no further than this TeleVue Powermate. While not technically a Barlow, this unique new 4-lens image amplifier performs the same functions, but at a higher level of optical correction. Barlow lenses have a negative power that diverges field rays, lengthening the effective focal length of the telescope and increasing the magnification . . .

    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. . . .
