Description

Sky-Watcher Flextube 400P Collapsible Dobsonian Telescope

The Ultimate Light Gatherer – 16″ !!

The Dobsonian telescopes are named after John Dobson, an amateur astronomer who designed a very simple but effective telescope, where the key factor is a large aperture for little money. His idea was to mount a Newton telescope on an easy-to-use alt-azimuth mount that does not need time-consuming alignments. Sky-Watcher improved the Dobson design building a collapsible system that allows the telescope to be easily stored or transported. The 3 metal bars, used to fully extend the tube, have an auto-lock spring loaded system that simplify the set up of the telescope so only one person is required to fully extend the tube. The rigidity of the telescope keeps the mirrors collimated and the tension control system keeps the telescope balanced, so it is not necessary to move heavy counterweights.

Just extend the tube, use the finderscope and point the telescope towards your favourite night sky objects – sit back and enjoy the great light gathering of the Sky-Watcher Dobsonian!

To top it off, the Sky-Watcher Collapsible Dobsonians are equipped with a 2″ Crayford focuser and focuser locking screw.

Accessories in the Box:

  • Finderscope 9X50 straight version
  • Eyepiece 1.25″ Super Plossl 25mm (72x) – apparent filed of view 52°
  • Eyepiece 1.25″ Super Plossl 10mm (180x) – apparent filed of view 52°
  • Eyepiece adapter from 2″ to 1.25″ with M42 thread
  • 2″ tube extension
