Product Description

For those observing targets 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" telescopes such as f/5 and f/4 refractors and reflectors. 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. Length, 5". Weighs 5.8 oz. One-year limited warranty.

Customer Reviews

Good even with my light polluted area...
After reading all about barlows and problems with things washing out and dimness becoming even worse, I am pleasantly surprised. I live in a light polluted are outside of Philadelphia. Even with looking at Saturn a few degrees over my neighbor's roof, this 3x barlow made the viewing awesome! I can't wait to get out to the country this weekend and get a better view with the barlow and XT8 8" dobs I use it on.

One thing that it certainly does magnify is the perceived speed of the turning Earth. With this 3x lens in place, Saturn moved out of the eyepiece within 15-20 seconds. Not any fault of the barlow, but certainly something that is magnified by the smaller field of view.

Great Barlow
Great Lens, I love it, sharp and clear, way better than any other barlow I have seen or used.
