Sky-Watcher Skyliner 254P FlexTube SynScan Go-To Wi-Fi - The powerful automated Dobson<\/h3>\n

The ultimate Dobson is born!<\/strong>
\nThe 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<\/strong> for transport, and a patented Motorized, Wi-Fi-connected Go-To<\/strong>. This telescope automatically locates over 42,900 celestial objects, tracks them in real time, and can be controlled at your fingertips from your smartphone.<\/p>\n

NEW :<\/strong> supplied with two wide-angle eyepieces (12.5 mm and 20 mm - 70\u00b0), a 1.25\u2033 adapter with brass clamping ring, a universal smartphone adapter and a Crayford 2\u2033 double-speed eyepiece holder. A complete set ready for use!<\/p>\n

SynScan Go-To technology with integrated Wi-Fi<\/h3>\n

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 :<\/p>\n

    \n
  • Automatically point over 42,900 celestial objects<\/li>\n
  • Enjoy a guided tour of the sky (\"Best Tonight\" function)<\/li>\n
  • Use the \"Point & Go\" function simply by touching your screen<\/li>\n
  • Identify objects observed in real time<\/li>\n
  • Remote telescope control via the Internet<\/li>\n
  • Add custom objects and improve pointing accuracy (PAE)<\/li>\n<\/ul>\n

    Its system with patented double encoder<\/strong> allows you to move the tube manually at any time without losing alignment - a unique freedom of use.<\/p>\n

    FlexTube retractable tube: more compact, more mobile<\/h3>\n

    The design Fully retractable FlexTube<\/strong> 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.<\/p>\n

    Powerful, bright optics<\/h3>\n

    The primary mirror 254 mm parabolic dish<\/strong> captures 56 % more light than a 200 mm telescope. With its RAQ\u2122 (Radiant\u2122 Aluminum Quartz) treatment, it offers reflectivity of up to 94 %, ensuring bright, high-contrast images rich in detail, whether of Saturn or distant galaxies.<\/p>\n
