The 80mm f5 is a well- proven performer which gives “rich- field“ views of star fields, clusters, nebulae, bright galaxies, planets, the Moon and (with correct filtering or by projection) the Sun, as well as excellent terrestrial views. Both telescopes give images whicha are crisp and with very little chromatic aberration. |

The Sky-Watcher 70mm (2.8") f/5 and 80mm (3.1") telescopes are two-element, air-spaced, fully multi- coated objective, refractors. The 80mm f5 is a well- proven performer which gives "rich- field" views of star fields, clusters, nebulae, bright galaxies, planets, the Moon and (with correct filtering or by projection) the Sun, as well as excellent terrestrial views. Both telescopes give images whicha are crisp and with very little chromatic aberration.
One of the greatest assets of these solidly built telescopes is portability. The light-weight optical tubes (1.25kg; 2.8lbs for the 70mm and 1.5kg; 3.3lbs for the 80mm), and the compressed lengths of about 380mm (15") and 480mm (18") make them "take it with me" telescopes. Their optical tubes can be adapted to fit into an airline carry-on bag, or into a hikers backpack. Whether they are to be used as a beginners telescope, a "rich-field", a backup, a guide scope or a travelling telescope, the very reasonable prices make them choices to seriously consider.
