The Explore Scientific 8" f/5.9 Dobsonian (Ruby Red) is a special-edition telescope that pairs powerful deep-sky optics with a striking design and an upgraded accessory bundle. Its 208mm parabolic mirror gathers over 800 times the light of the unaided eye, enough to reveal Saturn's rings and lunar craters. With a wide-field eyepiece, high-magnification Plössl, 2x Barlow, and smartphone adapter all included, this scope is built for observers who want 8" performance and everything needed to start exploring on night one.


Key Features
  • Powerful 208mm parabolic mirror — collects over 800x the light of the unaided eye, for exploring deep-sky targets like galaxies, nebulae, and star clusters
  • Fast f/5.9 optics — bright, moderately wide fields perfect for deep-sky sweeping and views of Jupiter's cloud bands and Saturn's ring system
  • Upgraded 70° wide-field eyepiece — the included 25mm eyepiece delivers a noticeably wider apparent field than standard Plössls
  • Ready to observe out of the box — a wide-field eyepiece, high-magnification Plössl, and 2x Barlow provide three magnifications (49x, 122x and 244x) without buying a single extra accessory
  • 2" Crayford focuser — with a 1.25" adapter for full eyepiece compatibility
  • Spring-tension Dobsonian base — maintains balance when you swap eyepieces or add a camera, with intuitive manual tracking
  • Rolled-steel construction — collimation can shift in transport, and a touch-up takes only a few minutes
  • Two-piece — under 39 lbs total (a 20 lb tube and an 18.7 lb base)
  • Smartphone adapter included — capture and share views with your phone camera
  • Standout ruby-red finish — housing the same optics as the standard model

Ideal For
  • First serious telescope owners stepping up to 8" aperture: the complete accessory bundle means nothing else to buy on day one
  • Visual deep-sky observers chasing galaxies, nebulae, and star clusters from backyard or dark-sky sites
  • Astrophotography-curious beginners ready to capture snapshots via smartphone before investing in dedicated imaging gear
