Sky-Watcher Skyliner 254P FlexTube SynScan Go-To Wi-Fi - The powerful automated Dobson

The ultimate Dobson is born!
The Sky-Watcher Skyliner 254P FlexTube SynScan Go-To combines everything that visual astronomers are looking for: a large 254 mm parabolic mirror, a design retractable FlexTube for transport, and a patented Motorized, Wi-Fi-connected Go-To. This telescope automatically locates over 42,900 celestial objects, tracks them in real time, and can be controlled at your fingertips from your smartphone.

NEW : supplied with two wide-angle eyepieces (12.5 mm and 20 mm - 70°), a 1.25″ adapter with brass clamping ring, a universal smartphone adapter and a Crayford 2″ double-speed eyepiece holder. A complete set ready for use!

SynScan Go-To technology with integrated Wi-Fi

Thanks to SynScan Go-To technology, this Dobson turns into a real observation assistant. Connect it to the free SynScan app (iOS / Android) or use the included SynScan controller to :

  • Automatically point over 42,900 celestial objects
  • Enjoy a guided tour of the sky ("Best Tonight" function)
  • Use the "Point & Go" function simply by touching your screen
  • Identify objects observed in real time
  • Remote telescope control via the Internet

Its system with patented double encoder allows you to move the tube manually at any time without losing alignment - a unique freedom of use.

FlexTube retractable tube: more compact, more mobile

The design Fully retractable FlexTube for easy storage and transport. The tube is reduced from 120 cm to a much shorter length, while retaining its rigidity thanks to a 3-point locking system.
