This Celestron AVX6N is a 6" fast focal ratio/wide field reflector optical tube on a robust go-to computerized German equatorial mount. The substantial 6” aperture of this Celestron reflector makes it an excellent scope for all-around solar system and deep space observing alike. It has 459x the light-gathering capacity of even the sharpest dark-adapted eye, allowing you to see faint deep space wonders that would be otherwise invisible. The go-to mount makes finding over 40,000 of those objects easy and automatic, so you spend more of your time looking at celestial wonders, and less time looking for them.
This Celestron reflector works well visually from many city and suburban sites, as its f/5 focal ratio keeps moderately light-polluted sky backgrounds reasonably dark to avoid washing out faint nebula detail. As with any scope, however, transporting the Celestron AVX6N to a dark sky observing site will markedly improve its performance on broad, faint deep sky objects at low powers.
In addition, the 750mm focal length of this Celestron makes it easy to achieve the high powers needed for detailed lunar and planetary observing. Simply add an optional Barlow lens, and/or additional optional higher power eyepieces, and this Celestron telescope will provide you with crisp and sharply detailed close-up views of the Moon and planets.
The scope’s lightweight optical tube and easily assembled go-to mount make it quick to set up and enjoy – either in your back yard or at a distant dark sky site. Its superb optical quality and reasonable price for a go-to scope make it an excellent buy for the beginning and advanced astronomer alike.
This Celestron Telescope’s Optical System . . .
Newtonian reflector optical tube: 6”aperture (750mm focal length f/5 parabolic primary mirror), guaranteed to be diffraction-limited. The optical tube is black-finished aluminum, to allow the mirrors to cool to ambient temperature more quickly. Also, the lower end of the tube is sealed to reduce image-degrading thermal currents within the optical tube. These features extend your undisturbed viewing time by minimizing the time you have to wait for the images to stabilize after you take your C6N outside in the cold air of late fall or winter.
The scope’s tube end rings are sturdy die cast aluminum, to protect the tube during transport and provide exceptionally rigid support for the optics. The mirror cell’s six-screw push/pull locking collimation system keeps the primary mirror aligned far longer than conventional mirror cells – so you spend more time observing, and less time adjusting the optics. The lightweight optical tube rotates in its felt-lined die cast cradle rings to bring the focuser and finder to the most comfortable viewing position. The mounting rings even include a built-in piggyback mount for wide field astrophotography. The 27” long aluminum optical tube weighs only 10 lbs., making it easy to transport and assemble in the field.
Finderscope: 6 x 30mm straight-through achromatic design, with a wide 7° field of view.
Focuser: 1.25” metal rack and pinion type.
Eyepiece: 1.25” 20mm Plössl (38x). The 1.3° field of the eyepiece is more than two and a half times the diameter of the Moon, for exciting views of large objects such as the Pleiades and the Lagoon Nebula.
Software: TheSkyX First Light Edition planetarium and sky-charting CD-ROM,with a database of 10,000 stars and objects it can plot and display on your Windows-based computer screen. That’s enough solar system and deep space detail to keep you busy observing for years, yet not so much that you’re overwhelmed by charts showing much more detail than your scope can usefully reveal. Custom sky chart printing lets you print out eyepiece finder charts to use with your telescope to help you locate and identify the planets and many famous and faint deep space nebulas, galaxies, and star clusters. There are 75 full color images of well-known celestial objects to help you identify them through your scope.
This Telescope’s Mount . . .
Heavy duty Advanced VX Series computerized go-to German equatorial mount: This scope’s new Advanced VX mount was specifically designed to provide optimum imaging performance for smaller telescopes (30 lbs and under). It has the imaging-friendly features of Celestron’s larger telescope mounts, such as permanent periodic error correction (PPEC) and the ability to Image across the meridian without doing a meridian flip, so you can seamlessly image the best part of the night sky.
Experienced imagers will love taking this portable mount to a dark sky site (the head weighs only 17 lbs, the tripod only 18 lbs,plus two 11 lb counterweights), as it provides all the performance of their larger observatory mounts in a portable package. If you’re new to imaging, the Advanced VX mount will help you get started with the hobby and keep up with your needs for years to come.
The mount includes dual-axis slewing/tracking low-cog DC servo motors with positioning encoders on each axis for go-to computer control. The new motors provide improved tracking performance and more power to handle an unbalanced load than previous Advanced Series drives. Built-in adjustable backlash compensation and permanent user-programmed periodic error correction (PPEC) permits precise corrections during astrophotography and when observing visually at high powers. The maximum slewing speed is a fast 4° per second.
The scope is supplied with a car battery cord to operate from the cigarette lighter plug of your car or from a rechargeable 12Vbattery pack. The mount requires a 12VDC 3.5A power source, so the Celestron 17amp hour capacity Power Tank #4517V is recommended for extended use in the field. The Power Tank can be recharged hundreds of times and will operate the scope all night long without danger of running out of power. Celestron AC adapter #2338PRO is also available to operate the scope from household AC in your back yard.
The three sliding 11 pound counterweights are locked in place with a single hand-tighten thumbscrew each, making it easy to rebalance the scope if you add heavy photographic accessories. The mount is easily capable of handling the scope and any reasonable combination of photographic accessories you might want to use. Snap-on covers keep the motor drives free from dust and debris. A set of optional vibration suppression pads #4525 under the tripod feet will improve the telescope damping time for steadier high power observing.
To make a casual polar alignment for visual use quick and easy, there’s a latitude scale and fine adjustment controls in both altitude and azimuth. The scope can be used over a wide 7° to 77° latitude range in both the northern and southern hemispheres. The scope includes Celestron’s unique All-Star computerized polar alignment that lets you do an accurate polar alignment even when Polaris is hidden by trees or buildings.
NexStar+ computer hand control: The supplied NexStar+ computerized hand control has an internal clock and a built-in database of more than 40,000 stars and deep space/solar system objects it can find for you. These include the complete RNGC, Messier, Caldwell, IC,and Abell catalogs; selected SAO stars, such as variables and multiple star systems; the planets, the Moon, and more. There is enhanced information on over200 of the most note-worthy objects.
You can also store and edit the right ascension and declination of 100 additional user-defined objects of your own choosing,such as the comet and asteroid coordinates published monthly in Astronomy and Sky & Telescope magazines. The computer control can find any of those objects with at your command, and accurately track them for visual or photographic application.
All of the database and telescope operation information is displayed on a double line, 16-character, liquid crystal display on the hand control. The NexStar+ hand control offers multiple language programming (English, French, Italian, German, Spanish). There are 19 fiber optic back-lit LED buttons to make it easy for you to control the computer without affecting your dark adapted vision. There are two AUX ports, an autoguider port, and anRS-232 communication port on the hand control that allows you to operate the telescope via a personal computer. The computer hand control software can be upgraded over the Internet from Celestron's website, assuring that you always have the most current software version at your command.
Several different alignment methods are built into the NexStar+ computer, allowing you to choose a level of computer accuracy in automatically finding objects with which you are comfortable. You can choose two-star align, quick align, one-star align, last alignment, or solar system align. Each of these computer-guided alignment methods is easily accomplished in only a few short minutes. You can be observing in less than 15 minutes after you first take your scope outdoors, including telescope assembly time.
In addition, the NexStar+ computer hand control is GPS-compatible (using an optional inexpensive SkySync GPS module) for full GPS (Global Positioning System) satellite accuracy. Adding GPS to the computer is something no competitive scope can do. With the Advanced VX Series go-to mount and the SkySync, orienting the scope in time and space on earth and aligning the scope on the sky becomes almost as easy as simply turning the scope on.
Adjustable height tripod: The tripod has 2” diameter steel legs with a center leg brace for rigidity, with excellent damping characteristics. The center leg brace is drilled to form a convenient accessory tray that holds 1.25" and 2" eyepiece to keep them up out of the dew-soaked grass.
Dovetail slide bar: An adjustable Vixen-style dovetail slide bar allows the optical tube to be quickly and precisely balanced fore and aft on the mount, eliminating the need for an extra counterweight to balance a camera or other accessories. Setup and takedown times are exceptionally fast,as a single large hand-tighten knob holds the optical tube in place. A second lock knob prevents the tube from sliding off the mount should the hand-tighten knob loosen.
Two-year warranty: All Celestron go-to telescopes have a two-year warranty, double that of competitive go-to scopes.
