  • Sky-Watcher Heritage 130P Tabletop Dobsonian

    130 mm of aperture that sits on a table instead of a tripod — the least compromised first telescope for anyone who does not want to fight a mount in the dark.

    ~$250VIEW
  • Celestron AstroMaster 70AZ Refractor

    Light, cheap and forgiving; suits a household that wants the Moon and the Galilean moons tonight rather than a new hobby.

  • Celestron StarSense Explorer DX 130AZ

    A phone dock plate-solves the sky and walks you onto the target, which suits anyone whose first scope died of not being able to find anything.
