- Goes Well With
A compact achromatic refractor with a 70 mm objective lens diameter and a 900 mm focal length. It will work well for a beginner observer, allowing observation of the Moon, the Sun (when using an appropriate solar filter), planets, bright star clusters, galaxies, or even bright nebulae.
The telescope is equipped with a simple equatorial mount with slow-motion controls, allowing smooth and intuitive tracking of the selected object.
The set includes a 90-degree diagonal and a so-called erecting lens, which allows observation of terrestrial objects. The set also includes 2 eyepieces in the Kellner system with focal lengths of 25 mm and 10 mm.
