Disassembly of the scope, which does not require 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 flow at high magnifications.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThis is an ideal workhorse for the deep-sky observers. A 254mm mirror collects hundreds of 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.\u003c\/p\u003e\n\u003cp\u003eThe significant differences between this telescope and the Explore Scientific Generation II model are:\u003c\/p\u003e\n\u003cp\u003e* White aluminum-tube secondary rather than a cage assembly\u003c\/p\u003e\n\u003cp\u003e* Single-speed focuser rather than a 2-speed focuser (upgrade requires a new focuser;
