Outline
A high quality 2” barlow lens using special ED glass to greatly reduce chromatic aberrations. Metal body, rugged grip, cemented doublet fully multi coated apo-achromatic lens, results in high resolution, contrast and greatly improved colour correction.

2" to 1.25" eyepiece adaptor with copper compression ring is included.

Ascension Barlow Lenses
Barlow lenses are used to multiply the focal length of the objective lens/mirror of your telescope and therefore its magnifying power. The benefits of using a Barlow lens will result in image magnification, improved eye relief and reduced spherical aberration in the eyepiece.

Barlow lenses can also be used with binoviewers that in certain cases are unable to reach focus, especially when used with Newtonian telescopes and refractors with short focus travel. The extended focal length provided by the Barlow will then make focusing possible. Ascension binoviewers are supplied with their own detachable barlow lens.

Ascension 2" ED barlow lens.
