  • 2.5x fully apochromatic Barlow for any 1.25" eyepieces
  • Three-element, fully-multicoated ED lens
  • Precision-machined aluminum barrel with high-quality black-anodized finish and knurled ring to aid in handling

The 2.5x Barlow is constructed with triplet design of 3-elements ED lens to eliminate the blue, purple and red chromatic aberration, and delivers sharp imaging in 2.5x magnification.  Its inner a brass compression ring is designed to avoid any scratch when clamping equipment tightly.  The inside surface of this tube is black-matted helps to enhance imaging contrast and absorb any disturbing light.

Practically, 2.5x is a pretty good balance between optical performance and usable magnification.  My advice is that you should avoid to choose any Barlow higher than 2.5x.
