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.
