The 1.25" 3-Element 2x Barlow Lens triples the power of any 1.25" telescope eyepiece.
- It's an ideal accessory for high-power lunar and planetary observation, as well as lunar and planetary imaging when used with a solar system camera or webcam. Use this handy magnification-boosting Barlow for up-close views of Mars, ringed Saturn, and gigantic Jupiter, or to study craters of the Moon in exquisite detail.
- The extra power boost provided by this Barlow Lens is especially helpful when used with short focal length telescopes that would otherwise not be able to achieve the desired magnification with very short focal length eyepieces.
- The 2x Barlow features an enhanced 3-element lens design which preserves the sharpness and contrast of your telescope and telescope eyepieces.
- The lens elements are fully multi-coated with anti-reflection coatings, and edge-blackened to provide maximum light throughput and optimal image contrast.
Advantages in a nutshell
- 2X short Barlow lens - ultra-short, 3-element Barlow - high contrast without chromatic aberration.
- Filter thread for any 1.25" filter, high-quality finish with protective dust cap.
- The combination of three lens elements means the Alstar 2X short Barlow provides particularly clear and sharp images.
- A built-in compression ring grips your eyepieces over a surface and not only at a point, as would be the case with unsophisticated models.
- Use this Barlow where in particular where you need a shorter length.

Much better than the two-element barlow that came with my telescope. This is basically a cheaper, rebranded version of the BST Starguider Barlow. The barlow is solidly built and its images are bright and sharp with zero false color or vignetting. Mars and Uranus looked great through it.
