The Explore Scientific FirstLight 10-inch solid-tube Dobsonian telescope is a deep-sky powerhouse for the dedicated visual observer. A Dobsonian is a large Newtonian reflector on a simple, stable base you aim by hand — the most light-gathering per dollar in astronomy. This solid-tube version keeps the optics rigidly aligned in a classic, rugged package.

Its 254mm (10-inch) mirror collects an enormous amount of light, and the 1270mm focal length (f/5) blends bright, wide views with the resolving power to show fine detail on faint objects.

Who it's for

Built for committed visual observers who want maximum aperture for galaxies and nebulae in a stable, straightforward package. New to the hobby? See our guide on how to pick your first telescope.

Key features

  • 10-inch (254mm) aperture for bright, detailed deep-sky views.
  • Solid-tube design that keeps the optics rigidly aligned.
  • f/5 optics (1270mm focal length) balancing wide field and resolution.
  • Smooth 2.5-inch HEX focuser with helical gearing for precise focus.
  • Convertible tube that can be used as a Newtonian on an EQ mount.
  • Sturdy, easy-to-assemble rocker-box base for stable, intuitive aiming.

What you'll see

Ten inches of aperture reveals faint galaxies, globular clusters resolved into individual stars, and the detailed structure of bright nebulae. On steady nights, planets show belts, Saturn's rings, and the Cassini division, while the Moon displays crisp craters, ridges, and rilles. Darker skies bring out even more faint detail.

Frequently asked questions

Solid tube or truss — which is better?
A solid tube keeps optics permanently aligned and is very rugged, while a truss packs down smaller for transport. Choose solid-tube for simplicity and rigidity.

Can it be used for astrophotography?
Its convertible tube can go on an EQ mount as a Newtonian, but Dobsonians are primarily visual instruments. It excels at observing rather than long-exposure imaging.

Is it heavy?
At around 61 lb total it separates into tube and base for transport, but it's a substantial instrument best kept fairly close to your observing spot.

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.
