The compact Sky-Watcher STARTRAVEL series are two-element, air-spaced, multi-coated objective, achromatic refractors, and are well proven performers for “Rich-Field” views of star fields, clusters, nebulae, bright galaxies, planets, the Moon and, the Sun (with correct safety filtering!), as well as giving excellent terrestrial views. These wide-field short-tube telescopes are also highly portable. They also are popular for use as guide scopes on larger telescopes. All models excel as fixed aperture lenses for both Astrophotography and terrestrial photography. Their “fast” focal ratios combined with today’s high-speed films make them useful for capturing lunar and solar eclipses as well as nature photographs. Tube material: Aluminium
