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. A non...

This fully antireflection-coated achromatic doublet Barlow increases the magnification 2x when used used in the star diagonal of a catadioptric (Schmidt-Cassegrain or Maksutov-Cassegrain) or refractor or in a reflector focuser. Due to the length of the barrel, care should be taken to be sure that the Barlow does not bottom out on the mirror face if used in a 2" diagonal with a 1.25" adapter. The inside of the barrel is anti-reflection threaded to improve contrast. There's a groove machined into the...

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.

All air-to-glass surfaces are expected to be fully coated with multiple layers of individually tuned ion-deposited anti-reflection materials for maximum light transmission and contrast. The lens edges and all internal metal surfaces are expected to be blackened to maximize the image contrast. It is anticipated that eyepieces will be held in place by a non-marring clamp ring that won’t scratch your eyepieces as a conventional metal thumbscrew can. A safety groove will probably be machined into the...

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 see...

By doubling the power of each eyepiece it is used with, this Astro-Tech Barlow effectively doubles the number of 1.25" eyepieces in your collection. It uses a two-element, fully-multicoated optical system for excellent color correction and sharpness and works best at focal ratios of f/6 and above. The lens edges are blackened for maximum image contrast. The body is made of precision CNC-machined aluminum and is anodized for long life. A thumbscrew holds eyepieces in place.

In the construction of solar filters and associated instrumentation, Coronado takes enormous care to optimize contrast by minimizing the number of components and designing them so that they do not result in creating residual reflections and spurious light near the image. Until recently, the only component not included in this overall approach was the eyepiece. Now the new CEMAX (Contrast Enhanced) series eyepiece fills this need. Specifically designed for use at H-Alpha and multi coated on every...
