The Sky-Watcher Dobsonian 10 Skyliner 250 Classic is a reflecting telescope with a parabolic Pyrex primary mirror that reduces spherical aberration. The Dobsonian altazimuth mount is operated manually and features an adjustable friction control handle, allowing the optical tube to move smoothly and stay in the position it is pointed.
The secondary mirror is supported by 0.5 mm-thick metal vanes to reduce diffraction and light loss. The 2" Crayford focuser comes with a 1.25" adapter for using eyepieces of both sizes.
