Product Description
This is a hybrid truss-tube Dobsonian because the secondary-mirror is held inside a tube (like a traditional Dobsonian telescope) rather than an open cage.
Nowhere do you get as much light for your effort like a good Dobsonian. 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.
This 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.
* White aluminum-tube secondary (rather than a cage assembly)
* Single-speed focuser rather than a 2-speed focuser (upgrade requires a new focuser; not just a 10:1 reduction knob)
* No cooling fans
Includes homemade black cloth shroud which will improve contrast at the eyepiece and offer dew protection for the primary mirror.
Comes with an excellent assortment of accessories
