Ideal for Daytime Terrestrial Observations as well as Deep-Sky Astronomical Use. The Sky-Watcher MERCURY-705 is a two-element, air-spaced achromatic refractor, that is a well proven performer for ‘Rich-Field’ views of comets, star fields, star clusters, nebulae, bright galaxies & planets, the Moon and the Sun (with proper safety filtering!), as well as giving excellent daytime terrestrial views. Supplied with the intuitive and easy to use AZ3 Alt-Azimuth mount, which provides excellent stability and precise control, via its slow motion cables, on both the horizontal (azimuth) and vertical (altitude) axes.
