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) 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 42,000 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!
Limited Warranty against defects in materials or workmanship for one year from date of purchase. This warranty is for the benefit of the original retail purchaser only. For complete warranty details contact us at 800-447-1001.
Please note this product was not designed or intended by the manufacturer for use by a child 12 years of age or younger.
Beginner Level - Suited for a wide range of uses, these products are simple to operate and set up. Some initial assembly may be required depending on the type of product. Optical instruments with this rating will have very good optical and mechanical quality. Great for families, young people, and folks who don't want to mess with equipment and complexity. Beginning level telescopes will show you countless lunar craters, Saturn's rings and a myriad of star clusters and nebulae! Referring to the manual is recommended.
Intermediate Level - These products offer higher performance and more advanced features than Level 1: Beginner models. They typically take a bit longer to learn and need some set-up or adjustments. But anyone with the slightest technical bent will have no problem getting familiar with these models. Referring to the manual is recommended.
Advanced Level - These products provide the best performance but may require more skill to master and appreciate. Optical instruments with this rating have exceptionally fine optics and mechanics. Some are easy to use but might be on the large or heavy side. Some are intended for specialized uses. These products will appeal to the more technically inclined. Referring to the manual is highly recommended.
For telescopes, the optical diameter (also known as aperture) is the size of a telescope's main light-collecting lens or primary mirror, measured in millimeters or inches. Telescopes with larger optical diameters collect more light, which leads to an increase in brightness and image resolution compared to smaller instruments.
For binoculars, the optical diameter (also known as objective lens diameter) is the size of each of the front-facing objective lenses of a binocular measured in millimeters. Binoculars with larger objective lenses collect more light, which increases image resolution and brightness. Binoculars with larger objective lenses are recommended for low light situations, and binoculars with at least 50mm or larger objective lenses are recommended for pleasing astronomical observations at night.
