Barlow Lenses

The RVO Horizon 2" barlow is made from high quality ED glass to increase contrast and brightness. The lenses are fully multi-coated for sharper views.

Increase your telescope magnification with Vixen's barlow lens with coated optics.

This barlow lens features a twist lock mechanism which makes your eyepiece/camera centralized. This makes more of the stars focused so it is far better for astrophotography. Objects that are in the center of the field are more likely to be pin points.

Barlow lenses offer an easy, economical way to increase the magnification range of your eyepieces, and Celestron carries a number of these highly useful lenses. A Barlow lens doubles the magnifying power of your eyepiece by doubling its effective focal length.

The Sky-Watcher NOMAD-5 5x Tele-Centric Focal Extender is a high-quality optical accessory with a variety of uses and connecting options for visual and imaging use.

2" ED Glass Barlow lens. Comes complete with 2" to 1.25" adaptor which allows the use of 1.25" and 2" eyepieces. Compression ringed for non marking grip. Superior quality glass.

Magnifies the image by just 1.6x. If you are having in focus issues or just want to magnify your image slightly, this is the barlow lens for you!

If you're looking for a good quality barlow lens to match up with the color correction of Takahashi apochromatic fluorite refractors, then here's your choice.

With teleextenders it is possible to extend the effective focal length of a telescope system, resulting in higher magnification for the observation of the moon, the planets or small Deep-Sky objects with the same eyepieces.

3-element Fully multi coated design. Brass pressure ring - Holds eyepiece more securely without damaging barrel. Rubber grip and hard black anodize finish with orange ring. Threaded for 1.25" filters.

The latest addition to the X-Cel LX line is perfect for astronomical observing, especially with short focal length telescopes. Fully multi-coated 3-element Apochromatic design offers superior sharpness and color correction.

With teleextenders it is possible to extend the effective focal length of a telescope system, resulting in higher magnification for the observation of the moon, the planets or small Deep-Sky objects with the same eyepieces.

Converts the Baader Hyperion Clickstop zoom into a 3.5mm to 10.5mm high power zoom eyepiece for greater magnification when needed. Also connects via the included T thread adaptor to a T ring for high power astro imaging.

Properly designed Barlows do wonderful things: They amplify power, slow the telescope's f/# (improving eyepiece sharpness), and give designers the opportunity to compensate for eyepiece aberrations.
