Barlow Lens 3x ED
For those observing targets where you need more power than your eyepieces alone can provide, we offer the new ED
Barlow lens to offer 3x magnification boost to any 1.25" eyepiece it's used with.
This is desirable for lunar and planetary observing and for extracting higher powers from fast telescopes such as f/5
and f/4 refractors and reflectors.
The features 3x ED Barlow lens use two-elements, fully multi-coated lenses with blackened edges for excellent color
correction and sharpness that effectively triples the focal length of the telescope's optics.
All housing is precision machined from aluminum and black anodized to a hard finish. The chrome portion of the barrel
are glare threaded and blackened inside to provide maximum contrast. The lens end of the barrel is threaded to accept any
standard 1.25" filters.
Fully multi-coated, 2-element achromatic with ED glass. Gives 3x magnification.
