This amazing 2” Barlow Lens with 2X magnification from GSO - TAIWAN uses a high quality ED Doublet lens design with one high index glass element featuring an unconventional partial dispersion in order to provide apochromatic performance.
Despite being available at an affordable price, this barlow offers superb color correction, along with blackened lens edges for maximum contrast. In general, this high quality barlow is an excellent option for anyone in need of a premium ED APO 2 Element Barlow Lens.
As an added bonus, the lens element cell can be detached from the barlow body and installed on most 2” eyepieces, providing a 1.5X enhancement in magnification.
