Sky-watcher Mercury 707 70mm (2.5″) F700 Refractor Telescope


The Mercury-707 is a significant step up from the Mercury-607 in terms of optical quality and performance, with its larger 70mm multi-coated objective lens, and will provide more rewarding views of the Moon, stars, bright planets and other night sky objects. The telescope can be freely moved in both horizontal and vertical axes and is equipped with a micro-adjustment elevation control.
