This high quality 2" barlow lens has extra low dispersion or ED optics to improve corrections and contrast over ordinary achromat optics. The lenses are fully coated and housed in a quality aluminium body with a rubber grip ring and blackened 2" barrel to prevent unwanted internal reflections. The 2" eyepiece holder and included 1.25" adapter are designed with a brass compression ring to securely hold eyepieces and protect the eyepiece barrel from scratches.
Great for use with 2" eyepieces to double the power but retain the eye relief and comfort, also well suited to imaging applications where higher magnifications are required. The use of ED (extra low dispersion) glass results in much better corrections and higher contrast. This quality barlow can only be used on a telescope equipped with a 2" focuser but can use both 1.25" and 2" eyepieces with the included compression adapter.
