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 spiral galaxy arms, nebula structure, Saturn's rings and Cassini Division, and fine lunar craters and rilles. With a wide-field eyepiece, high-magnification Plössl, 2x Barlow, and smartphone adapter all included, this scope is built for observers who want premium 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, resolving deep-sky targets like galaxies, nebulae, and star clusters with excellent contrast and sharp detail
  • Fast f/5.9 optics — bright, moderately wide fields perfect for deep-sky sweeping and high-contrast views of Jupiter's cloud bands and Saturn's ring system
  • Upgraded 70° wide-field eyepiece — the included 25mm eyepiece delivers immersive views with a noticeably wider apparent field than standard Plössls, making star-field sweeps and large nebulae come alive
  • Ready to observe out of the box — a wide-field eyepiece, high-magnification Plössl, and 2x Barlow provide four magnification options from 49x to 244x without buying a single extra accessory
  • Smooth 2" Crayford focuser — backlash-free focusing 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 push-to tracking
  • Durable rolled-steel construction — rigid tube holds collimation through transport and temperature changes
  • Lighter than the competition — under 38 lbs total, making one-person setup and car loading practical compared to 50+ lb competitors
  • Smartphone adapter included — capture and share views of the Moon, Jupiter, and Saturn with your phone camera
  • Standout ruby-red finish — turns heads at star parties and outreach events while housing the same precision 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
  • Star party hosts and outreach groups who want an eye-catching scope that draws a crowd and delivers impressive views to match
  • Astrophotography-curious beginners ready to capture lunar and planetary snapshots via smartphone before investing in dedicated imaging gear
  • Budget-conscious astronomers who want premium 8" aperture and a complete accessory package at a competitive price
