If your interest in amateur astronomy includes both observing and astrophotography, you need a telescope that’s up to the task - like the Orion Atlas 8 EQ-G GoTo Reflector Telescope. It’s an 8" aperture reflector with precision parabolic mirror optics with a precise heavy-duty GoTo equatorial mount, perfect for both visual and photographic forays into deep space.

The reflector telescope is built around its 203mm (8”) diameter parabolic primary mirror which has a focal length of 1000mm (f/4.9) and is center-marked for easier, more accurate collimation. The versatile combination of 8” aperture and 1000mm focal length is excellent for visually studying a wide variety of celestial objects, from relatively nearby planets to distant galaxies, and the f/4.9 focal ratio is plenty fast for deep-space CCD (charge coupled device) or film astrophotography. The included Orion Atlas EQ-G GoTo equatorial telescope mount has backlash compensation in both axes and programmable periodic error correction (PEC), which provides the precision required for astrophotographic guiding, performed either manually or with an autoguider via the ST-4 autoguider port, which is conveniently built right into the mount’s drive panel.

Speaking of the mount, the brawny Orion Atlas EQ-G GoTo mount and tripod provides incredibly stable support, thanks to its solid construction and 2"-diameter stainless steel legs, which adjust in height for optimally comfortable use. Internal DC stepper motors offer nine slew rates ranging from 2x to 800x sidereal, and three tracking rates: sidereal, lunar, and solar. You’ll find it easy and fun slewing from one object to the next at a clip of up to 3.4° per second.

With the GoTo Atlas EQ-G telescope mount, you can visit any of over 42,900 celestial objects with pushbutton ease. The hand controller has a two-line, backlit LCD screen and a red-illuminated keypad. Navigating the menu buttons is nicely intuitive and takes little time to master. The thorough computerized database includes the complete Messier, NGC, and IC catalogs of clusters, nebulas, and galaxies; eight planets; 100 named stars; and 25 user-defined objects you select yourself!

You get a host of great accessories with the Orion Atlas 8 EQ-G GoTo Reflector Telescope. An 8x40 achromatic finder scope lets you find objects to explore and aim the telescope precisely. A high-quality 1.25” 25mm Sirius Plossl telescope eyepiece is included for visual use of the telescope right out of the box. The 25mm telescope eyepiece yields 40x power magnification through the Atlas 8, which is ideal for general scanning of the heavens. The Orion Atlas 8 EQ-G GoTo Reflector Telescope tube assembly features a deluxe 2" Crayford-style focuser with a 1.25" adapter, allowing use of either 2" or 1.25" eyepieces as well as other accessories. Large knurled collimation knobs on the high-ventilation rear cell and a center mark on the primary mirror itself make optical alignment, also called collimation, easy and precise. We even include a simple collimation cap to help you align your telescope’s optics. 

The Atlas EQ-G mount requires an external 12-volt DC power supply or an AC-to-DC adapter to run off of household 110-volt AC, all sold separately.

Get the powerful and versatile Orion Atlas 8 EQ-G GoTo Reflector Telescope today and discover new worlds of astronomical and astrophotographic adventure!
