Description

• Delivers a 3x magnification boost to any 1.25″ eyepiece • Great for lunar and planetary observing • Perfect for extracting higher powers from short-focal-length telescopes • Accepts standard filters For those observing targets and applications where you need more power than your eyepieces alone can provide, we offer the Tri-Mag. It 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” tlescopes such as f/5 and f/4 refractors and reflectors. For long-exposure astrophoto-graphy, 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.
