The Skywatcher 6x30 is a straight-through telescope adapter that allows 6x magnification and features a 30 mm lens. It offers a clear, erect image (non-inverted) and crosshair optics for precise alignment. It includes a metal mount/attachment compatible with Sky-Watcher / Vixen / Synta style mounts. The compact metal optical tube is black in color, suitable for small to medium aperture telescopes, ideal for star-hopping and initial alignment.
