Dobson Sky-Watcher Skyliner-250P Classic - Visual power at your fingertips<\/h3>\n

A 254 mm Dobson telescope that combines performance, simplicity and excellent value for money.<\/strong>
\nWith its large 254 mm parabolic mirror, the Skyliner 254 captures impressive details of galaxies, nebulae, star clusters and planets. It's the ideal instrument for advanced visual observation, without compromise.<\/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 to prevent scratching your eyepieces, and a universal smartphone adapter - capture the beauty of the sky with your phone!<\/p>\n

What Sir Patrick Moore had to say<\/h3>\n

\"I've used a large number of telescopes; some good, some mediocre, some even bad. For me, the Sky-Watcher range is excellent, suitable for all amateurs - and the prices remain very affordable. Outstanding value for money. Use them and enjoy.\"
\n- Sir Patrick Moore CBE FRS (1923 - 2012)<\/em><\/p><\/blockquote>\n

A fluid, robust Dobson mount<\/h3>\n

The principle behind the Dobson mount is simple: smooth, intuitive azimuth movement, without motors or electronics. The whole unit is designed to easily follow a celestial object with the hand, while remaining perfectly stable. Set-up takes just a few minutes.<\/p>\n

High-end optics for the deep sky and planets<\/h3>\n

The primary mirror parabolic<\/strong> treated RAQ\u2122 offers up to 94 % of reflectivity. This enables faithful reproduction of detail, with excellent brightness. Thanks to its 254 mm diameter, this telescope collects 56 % more light than a 200 mm - a real difference on faint objects.<\/p>\n

Examples of observations (classic targets)<\/b><\/h3>\n
    \n
  • \n

    M42 - Great Orion Nebula<\/b><\/span> The sky: very spectacular, with a beautiful sense of relief. Under urban skies, you can sometimes make out a slight hint of color, depending on the conditions.<\/p>\n<\/li>\n

  • \n

    M57 - Ring Nebula<\/b><\/span> : withstands very high magnifications, around x250<\/b><\/span>, while maintaining a clean image.<\/p>\n<\/li>\n

  • \n

    Sagittarius (Lagoon, Trifid, etc.)<\/b><\/span> Nebulae: bright, detailed nebulae when well positioned in the sky.<\/p>\n<\/li>\n

  • \n

    M27 - Dumbbell Nebula<\/b><\/span> : very bright, easy to spot and particularly rewarding.<\/p>\n<\/li>\n

  • \n

    Planets<\/b><\/span> all the major planets are accessible and offer rich observations (depending on turbulence and height on the horizon).<\/p>\n<\/li>\n

  • \n

    M13 - Hercules globular cluster<\/b><\/span> : handles magnification very well (~x250<\/b><\/span>) and reveals superb granulation.<\/p>\n<\/li>\n<\/ul>\n

    <\/h3>\n

    How far the instrument can go (good sky + optimal conditions)<\/b><\/h3>\n
      \n
    • \n

      Double-double de la Lyre<\/b><\/span> Separation without difficulty at x250<\/b><\/span> with careful collimation.<\/p>\n<\/li>\n

    • \n

      M51 - Whirlpool Galaxy<\/b><\/span> The spiral arms start to appear when the sky is quite dark.<\/p>\n<\/li>\n

    • \n

      Dentelles du Cygne (without filter)<\/b><\/span> visible, but very delicate - a typical example of an object that rewards excellent skies.<\/p>\n<\/li>\n

    • \n

      M31 - Andromeda<\/b><\/span> The dust band can appear in good conditions.<\/p>\n<\/li>\n

    • \n

      Jupiter<\/b><\/span> : possible observation of key events such as the eclipses\/satellite occultations<\/b><\/span>.<\/p>\n<\/li>\n

    • \n

      Saturn<\/b><\/span> by exceptional seeing, we can go as far as x500<\/b><\/span> and achieve an impressive level of detail.<\/p>\n<\/li>\n<\/ul>\n
