  • Complete 5.1" aperture reflector telescope with full-size adjustable tripod and equatorial (EQ) mount for easy manual tracking of objects in the night sky
  • 900mm focal length and f/6.9 focal ratio makes the SpaceProbe 130 EQ an excellent telescope for viewing wide-field deep-sky objects like cloudy nebulas, distant galaxies, and sparkling open star clusters and bright globular star clusters
  • 130mm optics gulp up light from the night sky for wonderful views of the Moon and planets like Mars, Jupiter, and Saturn
  • Sturdy EQ-2 equatorial telescope mount features two slow-motion control knobs so you can keep what you're looking at in the eyepiece for extended views
  • Includes two Explorer II 1.25" Kellner eyepieces (25mm and 10mm focal lengths) for two different viewing magnifications, a 6x30 finder scope for easy aiming of the telescope, collimation cap, dust caps, accessory tray, Starry Night software, and more!
