The Celestron X-Cel LX is our choice for the best all-rounder selection of Barlow Lenses. You’ll be blown away by the quality of the planetary images you will capture with this 3x Barlow Lens from Celestron. If you have a decent scope, say a 130mm Newtonian, for example, you can see some great images of Jupiter’s red spot and three moons. If you want to view the lunar landscape, the Barlow will give you some excellent pictures or video if you prefer.

Owners of fast, short focal length telescopes will be excited by the Barlow’s triple magnification of any 1.25-inch eyepiece. Your images will be bright and sharp with excellent color correction thanks to the fully multi-coated, three-element apochromatic optics.

The lens barrel is threaded to accept any standard 1.25-inch filter and the brass compression ring holds the eyepiece in situ perfectly. In case you get too excited, a rubber grip around the Barlow helps to prevent accidental drops.

If you already own some eyepieces in the Celestron X-Cel Line, the attractive black anodized, with orange highlight design matches up perfectly.

Key Features

  • A brass compression ring holds the Barlow in Perfect position
  • Attractive black anodized body
  • The Barlow lens produces bright, sharp images
  • Triple magnification
  • A rubber grip to prevent any accidental drops of the eyepiece
  • Excellent optics in this price range

Our choice for the best budget Barlow Lens goes to the SVBONY 2x 1.25-inch. The range also includes a 3x and a 5x lens, but this review will discuss the 2x only.

The SVBONY is at an excellent price point considering the eyepiece’s body is metallic and not plastic, similar to other Barlows in this price range or even a little more expensive. There doesn’t appear to be any visible chromatic aberration.

Again considering this eyepiece’s cost, the optics’ quality is outstanding, with only a small reduction in light transmission to the eyepiece.

If you unscrew the lens portion from the eyepiece’s body and screw it onto the eyepiece you use, you’ll find you get approximately a 50% gain in magnification. For example, a 20x will then give you 30x, pretty useful.

Astronomy beginners or youngsters will find this Barlow easy to use and give them a nice view of Jupiter’s bands, Saturn’s rings, and the lunar surface.

Key Features

  • An excellent price point
  • All-metal body, and no plastic parts
  • The Barlow lens portion can be attached to another eyepiece for a 50% gain in magnification
  • Good Barlow lens for beginners
  • Sturdy build quality

The Celestron Luminous is the best Barlow lens capable of fitting both the 2-inch and 1.25-inch eyepieces of your telescope. And with the hard-anodized aluminum barrel is an extremely visually appealing Barlow lens. The lens is more significant than it looks in photos. A substantial build-quality, but not over heavy, so it’s straightforward to use. Includes a rubberized band around the middle for ease of use and reducing the risk of drops.

This Barlow is a two in one eyepiece because of the 1.25-inch adapter. Using the adapter doesn’t detract from a firm fit to your eyepiece. Great if you have a 2-inch focuser or diagonal on the telescope you own or are using. There is a compression ring for both the 2-inch eyepiece and the 1.25-inch adapter to secure the Barlow lens.

There’s fantastic image quality from the 4-element multi-coated apochromatic optics, and the images are sharp minus any unnecessary color. The filter thread will only accept 2-inch filters, and you will not be able to attach a DSLR camera because there’s no available thread on the O-ring. But that’s a small price to pay for such a top-quality Barlow lens.

Key Features

  • Excellent quality 4-element multi-coated apochromatic optics
  • An attractive and visually appealing hard-anodized body
  • A rubberized band to prevent accidental drops
  • A 1.25-inch adapter
  • There is a compression ring for secure attachment of the eyepieces

4. Televue 2x Barlow 1.25 inch

The Televue 2x Barlow is our premium choice of Barlow Lens

The eyepieces Televue produces have an outstanding reputation, and that also extends to their Barlow lens. It does look a little longer than many Barlows, but only 41mm extends from the focuser, so you will hardly notice.

The upper section of the body is black with attractive lime-green lettering; the middle section is silver, and the base is black. The brass compression ring will hold the Barlow firmly in position. By using a compression ring that prevents the damage, a tightening screw can cause.

The view quality is notable, and with only minor distortion around the edges of the field. If you’re looking for an excellent combination to go with the Televue Barlow lens, try a 10mm quality eyepiece.

Using a Barlow lens with eyepieces can reduce image quality, especially if the Barlow is of lower quality. But the Televue will provide excellent viewing images.

If the Barlow lens you want has to be of the highest quality, with excellent image purity, then the Televue is worth the extra cost.

Key Features

  • Impressive Build-quality
  • A Brass compression ring for secure fitting
  • Excellent optics
