  1. 2X 1.25" Barlow with compression ring

    $204.00
    This quality 2x Barlow is designed to mount in front of your star diagonal and uses a non-marring compression ring to hold the diagonal in place, rather than an easily-lost metal thumbscrew . . .
  2. Astro-Tech 2X achromatic Barlow for 1.25" eyepieces

    $29.95
    This physically short (3.1") Astro-Tech 2x achromatic Barlow is an inexpensive way to cleanly double the power of any 1.25" eyepiece in your collection . . .
  3. 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. . . .

  4. Tele Vue 2X Barlow for 1.25" eyepieces

    $133.01
    This 2-element Barlow has superb sharpness to match that of TeleVue eyepieces. Despite being "merely" an achromatic system, good design gives it better color correction at the edges of the field than some 3-element "apochromatic" Barlows.

    It is fully multicoated, with blackened lens edges and internal antireflection threading for excellent contrast. Its barrel is threaded for standard 1.25" fil . . .

  5. Astro-Tech 2X apochromatic ED Barlow for 2" eyepieces, with 1.25" adapter

    $59.95
    Here's an exceptional bargain - an optically premium 2" Astro-Tech 2x true apochromatic Barlow with ED glass and a 1.25" adapter at a low price you would normally expect to pay for an ordinary achromatic 1.25" Barlow . . .
  6. Celestron 2X Omni Barlow for 1.25" eyepieces

    $49.95
    This good quality Celestron 1.25" Barlow is fully multicoated for sharp, high contrast, 2x magnification . . .
  7. Celestron 2X Barlow for 1.25" eyepieces (includes T-adapter)

    $44.95
    While this Celestron 1.25" 2x achromatic Barlow can be used visually, it also has T-threads so it can be used as a T-adapter for lunar and terrestrial photography . . .
  8. Celestron X-Cel LX 2X 3-element Barlow for 1.25" eyepieces

    $94.95
    This 2x Celestron X-Cel LX three-lens air-spaced fully multicoated 1.25" Barlow performs a lot more expensively than it costs . . .
