Description
The popular “little scope that could” is now even better. The wide-field refractor that novices appreciate for its ease of use and big-scope owners value as a take-anywhere second scope now has fully multi-coated optics and comes with its own padded carrying case.
Its 80mm achromatic objective lens, short 400mm focal length (f/5.0), correct-image diagonal (1.25″) and 6×26 correct-image finder scope make the ST80-T perfect for casual stargazing or terrestrial viewing. The short focal length means you’ll see a beautifully wide field of view. And like all refractors, the unobstructed light path means sharper images with better definition and contrast
