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 : Comes with two wide-angle eyepieces (12.5 mm and 20 mm – 70°), a 1.25″ adapter with a brass clamping ring, a universal smartphone adapter, and a 2″ dual-speed Crayford eyepiece holder. A complete, ready-to-use kit!

SynScan Go-To technology with integrated Wi-Fi

Thanks to SynScan Go-To technology, this Dobsonian telescope becomes a true 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
  • Add custom objects and improve pointing accuracy (PAE)

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.

Powerful, bright optics

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

Skyliner 254P Go-To Wi-Fi highlights

  • Automatic tracking of over 42,900 celestial objects
  • Intuitive control via Wi-Fi or SynScan controller
  • Parabolic mirrors with RAQ™ high reflectivity treatment
  • Retractable FlexTube: greater transport comfort
  • 2-inch dual-speed Crayford eyepiece holder for precise focusing
  • Dual encoders enable manual movement without loss of alignment

Conclusion

The Sky-Watcher Skyliner 254P FlexTube SynScan Go-To Wi-Fi is the Swiss Army Knife of modern visual astronomy. It's the perfect choice for the astronomer who wants it all: power, compactness, automation, freedom of movement and precision. Perfect for observing thousands of celestial objects effortlessly, from your garden or in the countryside.

Frequently asked questions

Frequently asked questions

What can you see with the Sky-Watcher Skyliner-250P?

The Moon in great detail and the planets: Jupiter’s bands and moons, Saturn’s rings. With a diameter of 254 mm, it captures a great deal of light: under a very dark sky, bright galaxies and nebulae become visible. Its maximum useful magnification is approximately 508× (2 × the diameter in mm); in practice, atmospheric turbulence often limits observation to lower magnifications.

Which eyepieces are included, and what are their magnifications?

Two eyepieces are included: 20 mm and 12.5 mm. With a focal length of 1,200 mm, they provide 60× and 96× magnification. To determine the magnification of an eyepiece, divide the telescope's focal length by the eyepiece's focal length.

Is it easy to carry?

It is an imposing instrument: the tube weighs about 15 kg and is about 112 cm long, and the mount weighs about 17.5 kg. The tube and the base can be separated for transport.

Should we aim it at him?

Yes, just like any Newtonian telescope. A quick check every now and then is enough, especially after transporting it. With a collimation laser, it’s quick and easy. At f/4.7, it’s more demanding: a precise adjustment is clearly visible at high magnifications. The Sky-Watcher Collimation Guide (EN) explains the procedure.

Can we take pictures?

The motorized mount tracks objects: it’s ideal for filming the Moon and the planets with a smartphone or a small planetary camera, and the entire Moon fits within the field of view at low magnification. Long exposures of the deep sky remain limited, because an azimuth mount rotates the field of view.

What's in the box?

254 mm Newton Flextube optical tube, Dobsonian mount with accessory tray, built-in servos and Wi-Fi, 2″ Crayford eyepiece holder with 1.25″ adapter and camera adapter, 9×50 finder scope, 12.5 mm and 20 mm eyepieces, SynScan V6 controller.

Does the Sky-Watcher Skyliner-250P FlexTube SynScan Go-To come with a power supply?

No. The Sky-Watcher FlexTube SynScan mount does not come with a power supply. Required power supply: 12 V DC, center-positive. For home use, we recommend the'Pegasus Astro 12 V 10 A power supply with a 5.5 × 2.1 mm plug : regulated 12.5 V output, high current reserve, and it will later be able to power a Pegasus hub (Pocket Powerbox) for the camera and the anti-fog heating elements.
