The telescope optics: The Skywatcher Skyliner 150P Classic Dobsonian telescope contains a 153 mm parabolic Newtonian optic. It is very well suited to observing the moon and planets, but also many deep sky objects and much more in our night sky. The telescope mount: Dobsonian telescopes have an incredibly good price-performance ratio. The Dobsonian mount was introduced by John Dobson in the 1970’s and is a simple but efficient method of mounting a Newtonian telescope in azimuth. It is quick and easy to set up and allows movement in altitude and azimuth. The secret of the mount is the exact balance of the telescope and the use of special materials for friction that allow easy, gentle movement and keep the telescope safe when stationary. This mount was designed to be moved by hand. Sky-Watcher Dobsonian telescopes offer excellent performance when observing the moon, planets and deep sky objects such as galaxies and nebulae.
