Beginning astronomy enthusiasts seeking an affordable entry to
astronomical adventure will get it in spades with an Orion SpaceProbe 3
Altazimuth Reflector Telescope. Great for all-around astronomical
observing, this highly portable, uncomplicated telescope is just the
right size and weight for all family members, and just the right price
for parents.
The SpaceProbe 3 Altazimuth Reflector Telescope makes the night sky’s
treasures accessible right from the comfort of your own backyard. This
inexpensive reflector telescope will amaze you with revealing views of
Saturn’s picturesque rings, Jupiter’s moons, and the beautifully
cratered terrain of our own Moon’s surface. Built around a 3" (76mm)
diameter primary mirror, the Orion SpaceProbe 3 Altazimuth Reflector
Telescope also gathers enough light to snare the faint glows of some
very exotic star clusters and distant nebulas! The SpaceProbe 3’s focal
length of 700mm (f/9.2) provides sharp views of cosmic curiosities the
whole family can enjoy.
The aluminum Newtonian reflector optical tube features a 1.25"
rack-and-pinion focuser to ensure sharp images in the telescope
eyepiece. Speaking of which, each Orion SpaceProbe 3 Altazimuth
Reflector includes two interchangeable 1.25” Explorer II telescope
eyepieces, a 25mm and a 10mm. The 25mm eyepiece will yield 28x power
magnification in the SpaceProbe 3 while the 10mm eyepiece boosts the
magnification up to 70x power. A wide-field EZ Finder II reflex sight is
also included to aid in locating objects and aiming the telescope. An
adjustable-height tripod with accessory tray and aluminum legs is also
included with the SpaceProbe 3.
The Orion SpaceProbe 3 Altazimuth Reflector Telescope comes with an
altazimuth mount which allows simple up/down and left/right motion. The
altazimuth mount is lightweight and easy to use for anyone on the
family. (+Like all reflector telescopes, the SpaceProbe 3 is not
recommended for terrestrial viewing on land as the images will not be
right-side up.)
For the novice keen to discover what’s "out there," the affordable Orion
SpaceProbe 3 Altazimuth reflector Telescope provides a wonderful
opportunity!
