Description
The Orion SpaceProbe 3 Equatorial Reflector Telescope is highly portable and uncomplicated scope, great for all-around astronomical observing. SpaceProbe 3 reflector telescope makes the night sky's treasures accessible right from the backyard. It will reveal Saturn's picturesque rings, Jupiter's moons and the incredibly cratered terrain of the Moon's surface. It's 3"-diameter (76mm) primary mirror also gathers enough light to snare the faint glows of some very exotic star clusters and nebulas.
The aluminum Newtonian optical tube features a 1.25" rack-and-pinion focuser to ensure sharp images in the eyepiece. Speaking of which, each scope now comes with two interchangeable Explorer II eyepieces (1.25")-25mm (28x) and 10mm (70x)-as well as a wide-field and EZ Finder Reflex Sight to aid in locating objects. An adjustable-height tripod with accessory tray and aluminum legs is also included standard. The SpaceProbe 3 EQ comes with the EQ-1 equatorial mount. It allows easier manual "tracking" of celestial objects, once you get the hang of it. |
