ED Apo Refracting Telescopes

Our 80mm ED APO refractor Features the second to none technologies in both design and manufacture. It can provide superb images while offering the great convenience for users to carry (the OTA is retractive and can be put into small cases).

Strictly followed by ISO9001 Quality Controlling System, every single refractor is handcraft made and star tested by our highly qualified technicians whose average working experience are over 25 years.

The cemented apochromatic triplet in our 80mm ED type is made from extra- low dispersion glasses imported from Japan and are completely achromatic aberration free within the whole visible range of spectrum. These are distinct characters that have differed our ED type from those poorly made telescopes in quality.

With a focal length of 560mm and fast focal ratio of f/7, the ED80 is wonderfully suited for visual applications on both solar system and deep-sky objects as well as for prime-focus astrophotography and CCD imaging. Generally speaking, our ED refractor is the excellent choice for high-end users.
