Stable metal tube and adjustable mirror mounts for optimal imaging even after many years. Please note that this Dobsonian telescope 8 inch will need some assembly, especially the base, which is flat-packed.Exact 2 “Crayford focuser for precise focusing – with reduction to 1.25”.A Dobsonian (or Dob) is a type of telescope that was popularized by John Dobson in 1965. ![]() It offers the largest aperture for the price, delivering impressive visual views through the eyepiece. 94% mirror coating for a brighter, high-contrast image. A Dobsonian telescope is widely agreed to be the best possible first telescope for a beginner.High-quality parabolic optics with 200 mm aperture and 1200 mm focal length.The ease of use makes this telescope an ideal entry-level telescope. The telescope is still easy to transport. This scope features quality parts and accesories - the special roller-bearing construction, Crayford focuser. ![]() This 8 “f / 6 Dobsonian is ideal for observing nebulae and galaxies, but also for the moon and planets. Dobsonian reflector telescopes do not use tripods. Supporters also underline the fact that Newtonian reflector telescopes are free from chromatic aberration, aka colour distortion, which can be a bugbear of refracting telescopes that use a lens instead.GSO 8 inch DOB Telescope (Silver) with Free Mobile Holder and Solar FilmĪ high quality Dobsonian telescope with parabolic quality optics with 200 mm aperture.

The construction comprises a set up in which the light from the main or 'primary' mirror is deflected by a small flat secondary mirror, set at such an angle that it is sent to a magnifying eyepiece in the telescope's side. Search OPT University OPT carries top-quality telescopes, astronomy cameras, mounts, & astrophotography accessories online. ![]() What is a Newtonian telescope?Īs the name suggests, the Newtonian telescope references 17th Century inventor Isaac Newton and is also sometimes known as the Newtonian reflector. (Image credit: Orion) What is a compound telescope?Īlso known as catadioptric telescopes, as it sounds, this option combines refraction and reflection, via curved mirrors and lenses, for its optical system. As a best of both worlds solution, compound telescopes are typically recommended for astrophotography, while being ultra portable with it.
