The Libra 80/400 is a short-lens telescope on an equatorial mount with co-ordinate circles and smooth-running knobs.
The large 80mm entrance lens offers enhanced light collecting ability. But despite its vast aperture, the telescope is quite compact and would be a good choice for outdoor astronomy observing.
Due to the diagonal direct-vision prism of Amici's design, the instrument produces a correct, not inverted or horizontally imaged picture. This makes it not only suitable for astronomical observing, but also for ground-based applications.
The SIGETA Libra is mounted on a full-size tripod with a convenient accessory shelf before use. The EQ1 equatorial mount compensates for the Earth's rotation by turning the telescope with it at the right speed in the celestial equator plane: objects can therefore be "guided" across the sky for as long as desired.
The short focal length and large aperture make Libra suitable for astrophotography: use a good camera to take detailed and contrasting pictures of the starry sky.
