In theory, the classic 6” f/8 Newtonian should out-perform everything in its aperture apart from an APO and an f/15 Mak with a small secondary, both of which will be at least eight times the price.

153mm (6") f/1200 Parabolic Dobsonian Telescope

Magnifications (with eyepieces supplied): x48 & x120

Sky-Watcher Dobsonians feature a unique patented Tensioner/Carrying handle. By lifting the handles together, you can easily carry the whole unit in an upright position with the help of a friend.

Our view

The most economic way of attaining a long-focus small secondary Newtonian for sharp lunar and planetary images. In theory, the classic 6” f/8 Newtonian should out-perform everything in its aperture apart from an APO and an f/15 Mak with a small secondary, both of which will be at least eight times the price. The Skywatcher 6” f/8 tube assembly is available on different mounts, the Dobsonian being the least expensive.

Tips

Park it next to a slightly larger aperture short focal ratio Newtonian at a star party for comparison. The small secondary of this telescope will demonstrate why planetary observers prefer small secondary or zero secondary telescopes. Budget for a Baader UHC or OII 1.25 filter, a Neutral density filter or Baader polarising set for the moon, and an A4 sheet of Baader Astrosolar filter for the Sun in white light.
