80ED PRO OTA

Skywatcher Pro-Series ED refractors are built with a two-element air-spaced objective. The second element is made of the highest grade ED fluorite glass called FPL-53. This premium glass choice is a basic warranty for virtually no false color and for high contrast. The high standard set in material choice is also set in production. No effort is spared to reach optimal optical quality: Our best opticians give each objective a hand pitch polishing finishing touch. This dedication to perfection together with aspheric shaping technology are the best ways to reach a very good wavefront (*) which means virtually no aberrations and textbook star images. The quality of each ED Pro Series objective is monitored by means of Ronchi (*) test and star (**) test.

(*) The essential function of a telescope is gathering starlight without "disturbing" it. This means changing the path of the lightwaves without altering the lightwave itself. Lightwaves all together are referred to as a wavefront. Alterations in this wavefront caused by the optics should be avoided. A wavefront analysis by Ronchi test will show an absence of wavefront alterations if the black and white lines (interference pattern) are perfectly straight and parallel.

PRO-SERIES ED REFRACTORS

Premium quality, high performance telescopes for planetary and deep-sky observations as well as astrophotography and CCD imaging. The two-element objective lens is fully multi-coated and utilises special, extra-low dispersion FPL-53 fluorite glass for the virtual elimination of false colour. Performance of these telescopes will both delight and surprise the most critical observer, and can be genuinely compared to Apochromatic telescopes of other brands in price brackets normally way beyond the reach of the average user.

ED Apochromatic Optics: ED Fluorite glass elements minimise chromatic aberration, provide higher resolution and superior contrast. Colour fringing around objects is virtually eliminated with this type of optics.
