This new sharp, high resolution ED (extra low dispersion) refractor telescope comes with a FPL-53 glass lens which minimises chromatic aberration and provides higher resolution and superior contrast. Colour fringing around objects is completely eliminated with this type of optic. The SAXON ED refractor also features a backlash-free 2" Crayford focuser. The focuser wheels contain brushed-aluminium hubs with ridged rubber grip rings. The ED refractors are ideal for visual applications as well as astrophotography.
