The Explore Scientific 12-inch f/5 truss tube Dobsonian telescope is a large-aperture instrument for serious deep-sky visual observers. A Dobsonian telescope is a big Newtonian reflector on a simple, stable base you nudge by hand — the most light-gathering you can get for the money — and this Generation II truss design breaks down into manageable pieces for transport and tool-free setup.

Its 305mm (12-inch) mirror gathers a tremendous amount of light, and the 1525mm focal length (f/5) balances bright, wide views with the resolution to reveal fine detail on faint objects.

Who it's for

Built for dedicated visual observers who want serious aperture for galaxies, nebulae, and clusters in a scope that still transports. New to the hobby? See our guide on how to pick your first telescope.

Key features

  • 12-inch (305mm) aperture for bright, detailed deep-sky views.
  • Generation II truss design that collapses for transport and sets up without tools.
  • f/5 optics (1525mm focal length) balancing wide field and resolution.
  • Stable Dobsonian base for smooth, intuitive push-to aiming.
  • Large-aperture performance that pulls in faint galaxies and nebulae.

What you'll see

With 12 inches of aperture, this Dobsonian reveals faint galaxies with hints of structure, globular clusters resolved into pinpoint stars, and the detailed glow of nebulae. Planets show belts, Saturn's rings, and the Cassini division on steady nights, while the Moon displays crisp craters, ridges, and rilles. Darker skies unlock even more.

Frequently asked questions

Why choose a 12-inch Dobsonian?
It offers a big jump in light-gathering over smaller scopes, revealing far fainter galaxies and nebulae, while the truss design keeps it transportable.

Is it hard to set up?
No. The Generation II truss assembles without tools and breaks down into components for transport.

Is it good for astrophotography?
It's primarily a visual instrument. Its aperture is superb for observing, but Dobsonians aren't designed for long-exposure imaging.

Frequently Asked Questions

With a beginner telescope you can see a surprising amount — the craters and mountains on the Moon, the rings of Saturn, the moons of Jupiter, and star clusters like the Pleiades. As you get more comfortable, you can also spot nebulae and distant galaxies. Not sure which beginner telescope is right for you? Check out our Telescope Buying Guide.
