Product Description

  • 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

Additional Information

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.

Most Helpful Customer Reviews

Still new to astronomy so this review may not be very helpful. I used this Barlow lens with the 10mm eyepiece that came with my scope (100mm Orion Skyscanner)which I think gave me a max magnification of 120x (very close to the usable limit of the scope I have). I was able to see the rings of Saturn and it was a pretty small image but fairly clear; think eraser head centered in a silver dollar. Because of how the Barlow works and/or the high magnification the image does not stay centered very long and without a good tripod it can become very difficult to keep the image steady and in view. I think it would be wise to invest in a tripod that is designed for telescopes before playing too much with higher magnifications if you are starting out like me. Using it on a closer target like the moon, I was able to see a lot of the craters with a fair amount of detail. The image as far as I could tell was not distorted or had any false color but as I said I am new to this... The 120x... Read more
I got Orion's little lens and filter starter set (08889) and added this to it perfectly.
The kit has a place a 3X Barlow fits perfectly. With the 2X in the kit, I can find my DSO (Deep Space Object), then add the 2X to zoom in, and add the 3X for an effective 5X total.
So by adding this 3X, I have 2X, 3X, and 5X available at my viewing site.
This Barlow lens has decent enough build quality (I like the Orion brand), but the images it rendered were fairly soft. I know that's the nature of this entire approach (Barlow lenses), but I had hoped for a little better. Still worth keeping to put on for the kids.
