This is a Generation II telescope - all updates have been performed. 

This 16" Newtonian Truss Tube Dobsonian Telescope is the ideal workhorse for deep-sky observers. A 406mm mirror collects more than 2,400 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.

 

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.


No telescope type has changed the hobby quite as much as the Dobsonian. Before the popularization 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.

Love the Gen II!

It seems like all the issues I heard about with the first-generation truss tube dob have been resolved with the latest upgrades because it's been working wonderfully for me! It's also not too heavy for me to handle on my own, especially when disassembled.

Excellent quality telescope and views

I was so happy to find such a large aperture telescope in my price range. The optics are stunning and actually far better than I'd hoped for. This is a high quality product at a great price

Happy with my purchase

The revised dob platform is high quality and the views are phenomenal. I think this is an excellent value and a large aperture for the price
