What's good

  • +Dobsonian base is dead-simple — point and look
  • +6" aperture at a price reflectors on tripods can't match
  • +Stable, no wobble, no batteries

What to watch

  • Bulky — not a travel scope
  • Manual tracking means nudging the tube constantly
  • No GoTo, so you learn to star-hop

Our verdict

Ask experienced observers what they'd hand a serious beginner and a Dobsonian comes up every time. You're paying for the mirror, not a complicated mount, so every dollar buys aperture. The trade-off is no tracking — but learning to star-hop a Dob teaches you the sky in a way GoTo never will. For pure 'how much can I see per dollar', nothing beats a Dob.
