Description

This is a Generation II telescope. All updates have been performed on this telescope. No telescope type has changed the hobby quite as much as the Dobsonian. Before the introduction of the Dobsonian by John Dobson, the vast majority of amateur telescopes consisted of small telescopes with primitive mechanics - barely enough to see the polar caps of Mars or the rings of Saturn. Larger telescopes, such as the Schmidt-Cassegrain were reserved for the wealthy. The ingenious combination of simple yet effective mechanisms with the greatest possible opening gives the Dobsonian telescope a unique triumphant march around the world. Nowhere do you get as much light for your money like a good Dobson. Disassembly of the scope without tools ensures a trouble-free transport of this great scope even in small cars. The entire structure has been optimized for maximum stiffness with minimal weight. The combination of high altitude bearings with optimized aluminum structures allows fine adjustment flows at high magnifications.

The ideal workhorse for the deep sky observers. A 305mm mirror collects more than 1,800 times as much light as the naked eye. Details on planets and deep sky objects will be visible even for inexperienced observers. Bright star clusters are resolved to the core, and the sight of the terminator on the moon is an unforgettable experience.

Includes 2" focuser with helical gearing and 10:1 reduction; LED Red Dot Finder, collimation assist tool; soft light baffle and two radial main mirror fan for fast temperature equilibrium.

The scope is ready for the use with the Explore Scientific optional coma corrector.

Nicholas ★★★★★

Collimating the secondary mirror was a breeze with the new tool-free adjustment knobs. First clear night I had it out, the views of Jupiter's cloud bands were crisp and steady even at 200x. Really glad I waited for the Gen II version.

Brian R. ★★★★★

The Generation II updates are obvious the moment you start using it—that new truss lock mechanism feels rock solid and clicks into place with zero wobble. I've owned a solid-tube scope before, but this one breaks down small enough to fit in my trunk without a fight.

Ryan C. ★★★★★

The truss tube design makes setup a breeze compared to my old solid tube, and the Gen II updates are noticeable. Views of Jupiter were crisp and detailed even in my light-polluted backyard.
