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. The SAXON ED refractors also feature a backlash-free 2" Crayford focuser with 1.25" adapter. The focuser wheels contain brushed-aluminium hubs with ridged rubber grip rings. These ED refractors are ideal for visual applications as well as astrophotography.
