Explore Scientific 12" F/5 Dobsonian (Truss Tube)

Affordable, but more than capable of working as an absolute visual powerhouse, this 12" F/5 Dobsonian is one of Explore Scientific's finest of it's kind. The entire structure has been optimized for maximum stiffness with minimal weight, and the combination of high altitude bearings with optimized aluminum structures allows fine adjustment flows at high magnifications! Explore Scientific's 12" F/5 Dobsonian is ideal for deep sky observers, with a 254mm Mirror collecting over 1500 times as much as the naked eye. With this scope, even an Amateur observer can have an easy time of spotting fine details on planets and deep sky objects. You'll find that brighter star clusters are resolved to the very core, and that the Lunar Terminator is a sight to behold! With a scope like this, it's easy to create unforgettable experiences for yourself, to savor and hold on to for as long as you wish!

This telescope comes with a 2" focuser with helical gearing and 10:1 reduction; as well as a LED Red Dot Finder, a collimation assist tool; a soft light baffle and two radial main mirror fans for fast temperature equilibrium.
