Based on the Alt-Azimuth principle, the Dobsonian mount, made popular by John Dobson in the 1970s, is a quick and easy way to erect a Newtonian reflector. The Dobsonian mount is quick and simple to assemble and consists of a box-type mounting that rotates on a base in azimuth while allowing the telescope to pivot in altitude. The optical tube is balanced properly, and frictional materials are used, allowing it to move freely when pushed but to remain in place when not.
The mount is made to be operated manually rather than with slow motion controls. When it comes to viewing the Moon, planets, deep-sky objects like galaxies and nebulas, Sky-Watcher Dobsonians excel on all fronts, and they are now supplied with 12.5mm and 20mm 70-Degree Wide Angle Eyepieces, a 1.25" Adaptor with Brass Compression Ring to prevent marring of your eyepieces, and a Universal Smartphone Camera Adaptor !! The Sky Watcher Skyliner 150P Classic Dobsonian Astronomy Telescope features high quality parabolic primary mirrors to remove the spherical aberrations present in 'quick' focal length reflectors with spherical primary mirrors. All the light beams are parabolized by the mirrors to focus on a single point, producing clear, contrasty images that are rich in detail.
Sky-Watcher Deluxe Mirror Coatings: Today's reflectors often feature an aluminium coating on the mirror surface, followed by a protective layer of silicon monoxide or silicon dioxide. Compared to silicon monoxide, silicon dioxide creates a far more durable coat but costs more to apply since it needs specialised equipment. Because the mirror in the majority of reflectors is exposed to the elements and deterioration of the reflecting coating lowers the telescope's resolution, protection is necessary.
For maximum durability and long-term performance, Silicon Dioxide Multi-Coating is a standard feature on ALL Sky-Watcher reflectors.
