The Explore Scientific 10-inch f/5 truss-tube Dobsonian is a big-aperture deep-sky telescope in a portable, collapsible tube. A Dobsonian is a Newtonian reflector on a simple, steady alt-azimuth base — the most light per dollar you can buy. The truss design breaks down tool-free so a 10-inch scope fits in even a small car. This listing is the optical tube assembly (OTA).

Who it's for
Beginner-to-intermediate deep-sky observers who want maximum aperture that still travels. New to this design? See our Dobsonian telescopes explained guide.

  • 10-inch (254mm) mirror: gathers over 1,300 times more light than the naked eye for bright deep-sky views.
  • 1270mm focal length (f/5): a fast focal ratio that pairs well with wide-field eyepieces.
  • Truss-tube design: tool-free breakdown for easy transport and storage.
  • 2-inch focuser: accepts 2-inch and 1.25-inch eyepieces.
  • Red-dot finder: simple, intuitive aiming at bright targets.

What you'll see
Ten inches of aperture reveals structure in bright nebulae like Orion, resolves globular clusters into pinpoint stars, shows dozens of galaxies, and delivers crisp lunar and planetary detail. The bigger mirror simply shows fainter, more detailed views than smaller scopes.

Does it include the base?
This listing is described as the optical tube assembly (truss tube). Confirm base/rocker inclusion before ordering if you need the complete Dobsonian.

Do I need to collimate it?
Yes — like any Newtonian, the mirrors should be aligned (collimated) occasionally, especially after transport. It's a quick, learnable routine.

Is it good for beginners?
Dobsonians are famously beginner-friendly: point-and-look simplicity with lots of aperture. The truss design just makes this one easier to move.

Can I photograph with it?
It excels at visual observing and casual lunar/planetary snaps; long-exposure deep-sky imaging isn't its purpose.
