Delivers a 3x magnification boost to any 1.25 inch telescope eyepiece, greatly increasing your available viewing magnifications
For example: The Orion Tri-Mag 3x Barlow makes a 15mm eyepiece yield the same magnification as a 5mm eyepiece (15/3 = 5)
Great for high-power lunar and planetary observations
Perfect for extracting higher powers from short-focal-length telescopes
Threaded to accept standard 1.25 inch Orion eyepiece filters
When you need a lot more power than your telescope eyepieces alone can provide, we suggest using the 1.25 inch 3x Orion
Tri-Mag Barlow Lens. It gives a big 3x magnification boost to any 1.25 inch telescope eyepiece it's used with, ideal for
zooming in on observational targets for a closer look. This 3x power boost is desirable for lunar and planetary
observing, and for extracting higher powers from optically fast telescopes such as f/5 and f/4 refractors and
reflectors. For long-exposure astrophotography, the power amplification provided by the Tri-Mag 3x Barlow Lens allows
more precise guiding and use of a shorter focal length guide scope, such as a rich-field refractor (e.g., the Orion
ShortTube 80). With the Orion Tri-Mag 3x Barlow you can use longer-focal-length telescope eyepieces to achieve high
powers, which offers the benefits of better edge sharpness and more comfortable eye relief (optimal distance between
your eye and the eye lens) than you'd get using an equivalent high-power eyepiece without the Barlow. The Orion Tri-Mag
3x Barlow utilizes a multi-coated achromatic negative lens that effectively triples the focal length of the telescope's
optics. The Tri-Mag Barlow Lens housing is precision machined from aluminum and black anodized to a hard finish to stand
up to years of use. Both the Barlow housing and the chrome portion of the barrel are glare threaded and internally
blackened to provide maximum contrast and eliminate distracting reflections. The lens end of the Tri-Mag Barlow barrel
is threaded to accept standard 1.25 inch telescope eyepiece filters. Power-up your telescope eyepiece collection and
your telescope's performance with the new 1.25” 3x Orion Tri-Mag multi-coated Barlow Lens.
