Orion 1.25" 3x Tri-Mag Barlow Lens
Ways to Save
The Orion 1.25" 3x Tri-Mag Barlow Lens gives a big 3x magnification boost to any 1.25" eyepiece it's used with. This is desirable for lunar and planetary observing and for extracting higher powers from "fast" telescopes such as f/5 and f/4 refractors and reflectors. For long-exposure astrophotography, the power amplification provided by the Tri-Mag allows more precise guiding and use of a shorter guide scope, such as a rich-field refractor (e.g., the Orion ShortTube 80). With the Tri-Mag barlow you can use longer-focal-length eyepieces to achieve high powers, which offers the benefits of better edge sharpness and eye relief than you'd get using the equivalent high-power eyepiece without the barlow.
The Tri-Mag utilizes a multi-coated achromatic "negative" lens that effectively triples the focal length of the telescope's optics. The housing is precision machined from aluminum stock and black anodized to a hard finish. Both the housing and the chrome portion of the barrel are glare threaded and blackened inside to provide maximum contrast. The lens end of the barrel is threaded to accept standard filters. Power-up your eyepiece collection and your scope's performance with the new Tri-Mag 3x multi-coated barlow lens.
