Explore Scientific 12" f/4.5 Newtonian Truss Tube Dobsonian Telescope with Accessories – DOB1245-01

The Explore Scientific 12" f/4.5 Truss Tube Dobsonian delivers serious deep-sky performance in a portable and highly stable design. Built for observers who want massive aperture without the bulk, this hybrid truss system provides a rigid optical assembly that breaks down easily for transport. With a large 12" (305mm) primary mirror, enhanced reflectivity coatings, and the fast f/4.5 focal ratio, this telescope reveals breathtaking views of galaxies, nebulae, star clusters, and faint deep-sky details that smaller telescopes cannot match.

The open truss structure reduces weight and cool-down time while maintaining superb optical alignment. A smooth dual-speed Crayford focuser ensures precise focusing, even with heavy accessories. The azimuth and altitude bearings offer buttery-smooth motion for effortless manual tracking. Whether you're at home or traveling to a dark-sky site, the DOB1245-01 delivers powerful, immersive, wide-field observing.

Ideal for intermediate to advanced observers who want premium aperture with manageable portability.
