ED Refractor with German EQ5 equatorial mount is ideal for visual applications as well as astrophotography. The new sharp, high resolution SAXON ED refractors contain one element made from ED (Extra-low Dispersion) FPL-53 glass. This glass minimises chromatic aberration, provides higher resolution and superior contrast. Colour fringing around objects is completely eliminated with these optics.
