Explore Scientific 10″ f/5 Truss-Tube Dobsonian Telescope OTA (DOB1045)

A Serious Deep-Sky Telescope That You Can Actually Take Anywhere

The 10" f/5 Truss-Tube Dobsonian packs a massive 254mm mirror into a design that breaks down for transport and storage without any tools. That mirror gathers dramatically more light than smaller beginner scopes — enough to reveal faint galaxies, nebulae, and star clusters even under average skies.

The truss-tube design is the key advantage here: instead of a heavy, awkward solid tube, the telescope collapses into a compact rocker box and a bundle of truss poles, fitting easily into a car without a roof rack or trailer.

What You Can See

• Galaxies: Andromeda, Whirlpool, Sombrero, and hundreds more
• Nebulae: Orion, Lagoon, Ring Nebula, and fainter deep-sky objects
• Star clusters: Globular and open clusters in rich detail
• Moon and planets: Craters, cloud bands, Saturn's rings, Jupiter's moons
