Unique APO refractor for experienced astrophotographers.

Unique APO refractor for experienced astrophotographers

THE WO Star is the star of William Optics’ telescopes. The apochromatic refractor has been specially developed for astrophotography. Due to a unique patented design, the triplet houses four lens elements in three groups (2-1-1). They are made of FPL-53 (Ohara) fluorite glass and almost completely eliminate colour errors. Large areas of nebulae and galaxies are especially good targets for observation.
