Thanks to its small size and lightweight design, this high-quality fluorite refractor is ideal for excursions and air travel.
It displays razor sharp and bright stars across the entire field of view of the full-frame image sensor (95% illumination with 44 mm image circle).
The FL55SSS turns into a fast F/4.3 astrograph with the optional flattener and focal reducer. It allows you to use extremely short exposure times and a provides a large field of view for large nebulae or comets.
Despite the small aperture, the FL55SS features a high-resolution HR eyepiece that produces stunningly clear images of the moon and the bright planets.
When used for astrophotography, it delivers razor-sharp images of stars that are guaranteed to impress.
