The orthoscopic component provides the high contrast, low ghosting, flat field, and edge to edge image sharpness for which Abbe-type orthos are justly famous. The ED Barlow component provides higher magnification without adding or subtracting anything from the ortho’s superb color correction.

The 2.8mm Takahashi makes an excellent lunar and planetary eyepiece for the new generation of affordable fast focal ratio apochromatic refractors, as well as fast focal ratio Schmidt-Newtonian and Dobsonian reflectors of f/6 and under. It will typically provide excessively high powers with scope focal ratios longer than f/6 or f/7 and is not recommended for scopes in this range.
