Nights under the stars will never be quite the same with the Orion Atlas 10" EQ-G GoTo Reflector Telescope. Instead they'll be much, much more rewarding. This scope's huge 10" aperture optics and precise, heavy-duty computerized GoTo mount will show you what big-telescope performance is all about.

The most noteworthy feature of the 10" Atlas EQ-G is the optics. With a precisely crafted 10" (254 mm) parabolic mirror with 1200 mm focal length (f/4.7 focal ratio), this scope offers gigantic views with extremely high resolution and sharpness. You'll find yourself having a hard time taking your eyes off the incredibly gorgeous bright views of subtle deep sky objects that telescopes with smaller apertures are unable to reveal. This doesn't even take into account the the breathtaking looks this reflector will provide of the Moon and neighboring planets. An included 2" Crayford focuser offers smooth backlash-free adjustments for accurate performance and comes with a 1.25" adapter for compatibility with both 2" and 1.25" eyepieces and accessories. This telescope kit also includes 25 mm and 10 mm 1.25" Sirius Plossl eyepieces, as well as a 9x50 finderscope for help aiming this massive Newtonian reflector.

As for the Atlas EQ-G equatorial telescope mount, this efficient computerized mount offers rock-solid stability and support to go along with automated GoTo control, thanks to dual internal stepper motors that give the scope a slew rate of up to 3.4º per second with remarkably low periodic error tracking. Visit any of the over 42,000 celestial objects in the Atlas EQ-G's computerized database with pushbutton simplicity with the GoTo hand controller. The Atlas EQ-G equatorial mount offers backlash compensation in each axis, as well as programmable periodic error correction (PEC) to provide the accuracy essential for astrophotographic guiding using a dedicated autoguider. Plus, the Atlas EQ-G drive base even incorporates an ST-4 autoguider port. Finally, a height-adjustable stainless steel tripod with thick 2" diameter legs rounds out the 10" Atlas EQ-G support system.

An external 12-volt DC power supply or AC-to-DC adapter to run off 110-volt AC, such as the Orion Dynamo Pro (available separately) is required.

For owners of the Atlas EQ-G GoTo Mount whose version of the GoTo hand controller is 3.0 or greater, the GoTo hand controller's firmware can be updated over the internet.
