Sky-Watcher Classic 250P 10" Traditional Dobsonian Optical Tube Assembly

The 250P 10" Traditional Dobsonian Optical Tube Assembly from Sky-Watcher features an easy-to-use design that delivers beautiful views of the night sky. This Dob uses a highly reflective borosilicate parabolic primary mirror, polished and coated with Sky-Watcher's Radiant Aluminum Quartz, to deliver light from faint objects to the eyepiece. The design is ideal for observation of nebulae, star clusters, and galaxies. The wide 10" aperture admits 1,235 times more light than the human eye.

The telescope can support both 1.25" accessories as well as the heavier 2" eyepieces, allowing you to use virtually any eyepiece on the market. It includes two 1.25" eyepieces, a 1.25" adapter, a 2" eyepiece adapter, dust caps, and a 9x50 finder scope.

  • Large 10" aperture is able to resolve dim deep-space objects like wispy nebulae and galaxies
  • Fast f/4.7 focal ratio ensures a wide field of view, maximum light throughput
  • Long 1200mm focal length helps to produce fast focal ratio and moderate magnification potential
  • Borosilicate parabolic primary mirror
  • Radiant Aluminum Quartz mirror coatings bring the reflectivity to 94%
  • Resolution: 0.46 arcsec (Dawes Limit), 0.55 arcsec (Rayleigh Limit)
  • 64mm secondary diameter mirror; Obstruction: 25% by diameter, 6% by area
  • 25 and 10mm Super (modified Kellner) eyepieces, 48x and 120x magnification respectively
