GSO 5X Barlow Lens

Product Details

If you need more power than your eyepieces alone can provide, we offer a new apochromatic 5x Barlow lens from GSO (Guan Sheng Optical) to give a big magnification boost to any 1.25" eyepiece it's used with.

Nothing has been compromised in GSO's latest and finest offering. This Barlow features an air-spaced, three-element, apo design with fully multicoated optics. The housing is precision machined from aluminum stock and black anodized to a hard finish. The lens edges and inner barrel are blackened to provide maximum contrast. The Barlow body includes a safety undercut on the lower barrel and a brass compression ring so that your eyepiece barrels are not marred by the captive set screw. The 5x model has a clear aperture of 13mm, but it is not threaded to accept 1.25" filters.

For those blessed with great optics and dark skies, the 5x could be an exciting new addition to your arsenal for visual and photographic use. If you've never used such a powerful barlow before, please be aware that to get the best out of this barlow, you need to use it with a good telescope, a good eyepiece and under good seeing conditions.
