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.
