Bright wide views at low power can capture more than one deep-sky object in the field!
Disassembly of this 12-inch Dobsonian telescope without tools ensures a trouble-free transport of this large aperture telescope, even in small cars. The entire structure of the Explore Scientific Dobsonian has been optimized for maximum stiffness with minimal weight.
