Newtonian reflector. Aperture: 114mm. Focal length: 500mm

Optical design
Aperture – the diameter of the light-collecting lens (refractors and catadioptric) or mirror (reflectors) that the telescope uses to collect light
Focal length – the distance from the primary lens or mirror to the point at which the light is focused

Levenhuk Skyline BASE 120S is a classic Newtonian reflector, ideal for deep-sky observations. You can see nebulae, double stars, globular and open clusters, galaxies – all the Messier objects and some objects from the NGC catalog can be studied. You will be able to see the Moon and the planets of the solar system. The telescope is designed for beginner astronomers, i.e. it should not be difficult to use for those who have not previously dealt with any advanced optics.

The primary mirror, which is 114mm in diameter, transmits sharp, clear, and detailed images. The telescope comes with the accessories that are necessary for observation, namely two eyepieces: a short-focus eyepiece provides 125x magnification and a long-focus eyepiece provides 25x magnification. Another accessory is a finderscope with 5x magnification that is designed for precise pointing at astronomical objects.

This telescope is easy to operate. The optical tube is mounted on an alt-azimuth mount that allows for moving the optical tube like an ordinary spotting scope – upwards, downwards, to the left, to the right. The mount adjusts on a standard aluminum tripod, stable even on rough surfaces. You can install an accessory tray on a tripod.
