Optical power, mechanical fluidity and ease of use: this 254 mm Dobson ticks all the boxes!
With a 254-mm parabolic primary mirror, this telescope captures striking details of the faintest deep-sky objects while delivering sharp planetary images. Its dual-format 1.25″ / 2″ Crayford focuser ensures precise focusing, even with heavy accessories.
The Dobson mount is based on a simple, robust alt-azimuth principle, popularized in the 70s by John Dobson. The optical tube pivots on two axes thanks to a wooden base, with an adjusted friction system that allows fluid movement by hand while maintaining the chosen position. The result: a telescope quick to set up and pleasant to usewithout complex adjustments.
Unlike spherical mirrors, parabolic mirrors correct the optical aberrations typical of short focal length telescopes. Here, RAQ™ (Radiant™ Aluminum Quartz) treatment ensures up to 94 % reflectivitywith excellent durability over time. The ultra-thin 0.5 mm secondary support reduces diffraction for more punctual stars.
The Sky-Watcher Skyliner 254/1200 is the ideal companion for the demanding amateur astronomer. Whether you want to scrutinize the fine details of Jupiter, follow the phases of Venus or dive into the Milky Way, this telescope offers the power, precision and simplicity you need. A safe, high-performance choice for advanced visual observation.
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.
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.
It is an imposing instrument: the tube weighs about 15 kg and is approximately 112 cm long, and the mount weighs about 12.2 kg. The tube and the base can be separated for transport.
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.
The included smartphone adapter lets you take souvenir photos of the Moon and the planets—but that's all. Deep-sky photography isn't possible: the mount doesn't track the sky's movement.
254 mm Newton Flextube optical tube, Dobsonian mount with accessory tray, 2″ Crayford eyepiece holder with 10:1 dual-speed focuser and 1.25″ and 2″ adapters, 9×50 finder scope, 12.5 mm and 20 mm eyepieces, smartphone adapter.
Here are a few accessories we've selected for this model, depending on your needs.
1.25-inch filter designed to screw onto a compatible eyepiece.
Barlow Tele Vue 2×; magnification limited by the sky and the telescope.
An alternative to the eyepieces already included in the kit.
Baader 8–24 mm zoom lens (sold separately); the dedicated Barlow lens is sold separately.
2.25× Barlow lens, designed to be used with the Baader zoom lens (sold separately).
Nagler 13 mm, our favorite; an alternative to other eyepieces.
Zoom 3–8 mm: Adjust the magnification to suit the conditions and check the focus.
