| 126 2x Barlow for 1.25" eyepieces - The Meade #126 is physically very short (2.5") and was designed to fit into the star diagonal of the Meade ETX Maksutov-Cassegrains to keep the telescope/eyepiece height comfortably low. However, it can also be used in the 1.25" star diagonal of any type or brand of telescope for true 2x magnification. |

| 2x Barlow for 1.25" eyepieces (includes T-adapter) - This 1.25" 2x achromatic Barlow lens can be used visually, but the eyepiece holder portion also has integral T-threads so it can be used as a T-adapter for lunar and terrestrial photography. The physically short (2.9") Barlow fits into the rack and pinion focuser drawtube of most equatorial refractors and reflectors. It can also be used in the 1.25" visual back or eyepiece holder of most Schmidt-Cassegrain or Maksutov-Cassegrain telescopes. However, use with these scopes is not particularly recommended... |

| 2x Barlow for 1.25' eyepieces - It is fully multicoated, with blackened lens edges and internal antireflection threading for excellent contrast. Its barrel is threaded for standard 1.25" filters. There's an undercut safety groove in the barrel that helps hold the Barlow in place should the focuser thumbscrew accidentally loosen. A captive thumbscrew (that can't be lost in the field) holds your eyepieces in place. It has a 3.75" length that allows it to be used in star diagonals. |

| 2x Omni Barlow for 1.25" eyepieces - This is a good quality 1.25" 2x two-element fully multicoated Barlow. Its relatively short 3" length allows use in star diagonals. A thumbscrew holds eyepieces in place. The titanium-colored body has blackened internal antireflection threading for improved contrast. Comes with plastic covers for both ends of the Barlow to keep the optics dust free. |

| Shorty" 2x Barlow for 1.25" eyepieces - The “Shorty" Barlow gets its name from its compact size. It is just 3" long end to end – about half the length of a standard Barlow lens. It fits easily into any 1.25" star diagonal, so it’s great to use with refractors and Schmidt-Cassegrains. In fact, it works with any type of telescope, but it’s best at focal ratios of f/6 and above. |

| 2.4x Dakin Barlow for 1.25' eyepieces - This Ralph Dakin doublet design is considered by many professional astronomers to be the Rolls-Royce of Barlows. It has a magnification of 2.4x for non-repeating eyepiece powers. A non-marring nylon thumbscrew holds eyepieces securely in place. The lenses are antireflection coated, but not multicoated. One reason not to multicoat is to eliminate or greatly reduce a phenomenon known as "narrow angle light scatter." Multicoatings have more narrow angle scatter than single layer coatings. You can... |

| 2x Barlow DX for 1.25" eyepieces - This high quality fully-multicoated air-spaced triplet achromatic Barlow increases the magnification 2x when used in the star diagonal of a catadioptric telescope (Schmidt-Cassegrain or Maksutov-Cassegrain) or refractor or in the focuser of a reflector. It increases the magnification 4x when used in front of a catadioptric or refractor's star diagonal. A thumbscrew holds eyepieces in place. An undercut groove in the barrel that interlocks with the focuser or star diagonal’s thumbscrew helps prevent... |

| 3x Barlow for 1.25' eyepieces - If you need a high quality, medium high power Barlow for 1.25" eyepieces, look no further than this TeleVue. It’s a 2-lens achromatic design with superb sharpness to match that of TeleVue eyepieces. It is fully multicoated, with blackened lens edges and internal antireflection threading for excellent contrast. Its barrel is threaded for standard 1.25" filters. There's an undercut safety groove in the barrel that helps hold the Barlow in place should the focuser thumbscrew accidentally loosen.... |
