Starbright XLT optics
This advanced optical coatings package includes multiple layers of vacuum-deposited high reflectivity aluminum on both primary and secondary mirrors. The coating layers are enhanced with titanium dioxide for maximum reflectivity and then overcoated with a protective layer of silicon monoxide (quartz) for long life.

A unique combination of magnesium fluoride and hafnium dioxide high transmission antireflection coatings is vacuum-deposited on both sides of the Schmidt corrector lens for maximum light throughput and contrast. The corrector lens itself is made of high transmission water white float glass instead of the conventional soda lime glass (which has 3.5% lower transmission than water white glass) that’s used in other telescopes.

Starbright XLT multicoatings give you higher light transmission for brighter deep space images and shorter exposure times during CCD and DSLR photography. Across the total visual/photographic spectrum from 400nm to 750nm, independent laboratory tests show the new Starbright XLT coatings are 16% brighter overall than even the original industry-standard Starbright multicoatings. The XLT coatings also visibly increase the contrast on subtle lunar, planetary, and nebula details when compared with a scope with standard coatings or ordinary multicoatings.

NexStar CGEM computer
The NexStar computer hand control supplied with the Celestron CGEM telescopes is powered by the CGEM mount itself. No extra batteries or power supplies are needed. The

The NexStar computer has a built-in database of more than 40,000 stars and objects it can find and track for you. These include the complete RNGC, Messier, Caldwell, IC, and Abell catalogs; selected SAO stars; the planets, the Moon, and others. The custom database lists of all the most famous deep-sky objects by name and catalog number; the most beautiful double, triple and quadruple stars; selected variable stars; non-planetary solar system objects; and asterisms. You can also store and edit the right ascension and declination of 400 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 only a few keystrokes, and track them with high accuracy for visual or photographic applications. There is enhanced information on over 200 of the most note-worthy objects.

All of the database and mount operation information is displayed on a double line, 16-character, liquid crystal display on the NexStar hand control. There are 19 fiber optic backlit LED buttons to make it easy for you to control the NexStar computer without affecting your dark-adapted vision. An RS-232 communication port on the hand control allows you to operate your telescope remotely via a personal computer using the supplied RS-232 cable and NexRemote software CD-ROM.

The NexStar hand control provides a constant digital r. a. and dec readout of your scope’s position on the sky. This provides much greater accuracy than conventional manual setting circles for star-hopping or locating objects by their celestial coordinates alone, should you want to observe the old-fashioned way without using the computer to find objects for you.

The software built into the CGEM NexStar hand control includes mount calibration, database filter limits, hibernate, five alignment procedures, user-defined slew limits, a new "All-Star" polar alignment routine that uses any bright star for a quick and accurate polar alignment, and more. Built-in adjustable backlash compensation permits precise corrections during astrophotography and when observing visually at high powers. A high precision pointing subroutine in the computer lets you point accurately at objects that you want to photograph that are too dim to be seen though the scope.

The software includes permanent programmable periodic error correction (PEC) to correct for the minor periodic tracking errors inherent to all worm drives that might otherwise mar your long exposure photographs. The NexStar computer retains the PEC corrections when it is powered down. The hand control and motor control software is flash-upgradeable to allow you to download the latest product updates over the Internet to keep your NexStar computer control always at the cutting edge of technology.

Five different alignment methods are built into the NexStar computer – 2-star align, quick align, 1-star align, last alignment, and solar system align – allowing you to choose a level of computer accuracy in automatically finding objects with which you are comfortable. Alignment is easily accomplished in only a few short minutes. You can be observing in less than 15 minutes after you first take your CGEM-mounted scope outdoors.

In addition, the NexStar computer hand control is GPS-compatible (using an optional inexpensive CN16 GPS module) for full GPS (Global Positioning System) satellite accuracy. Adding GPS to the computer is something no competitively-priced mount can do. Once the scope is approximately polar aligned, the 16-channel CN16 GPS system uses signals from government satellites to calculate the scope’s location on earth with an accuracy measured in meters. The system also calculates the current time based on the split second accuracy of the GPS time signals. After the CN16 quickly completes these calculations and enters the information into the computer control for you automatically, the computer can then orient the scope with the sky, slew to a pair of guide stars, ask you to confirm that the stars are in the center of the field (and center them if they’re not precisely aligned), and then start finding and tracking over 40,000 objects for you at your command. With the CGEM go-to mount and the CN16, orienting your scope in time and space on earth and aligning it on the sky becomes almost as easy a task as simply turning the mount on.

Celestron EdgeHD optics
   Celestron EdgeHD high definition optics are aplanatic, or corrected for spherical aberration. They are essentially conventional Schmidt-Cassegrain optics (spherical primary mirror, spherical secondary mirror, and full-aperture Schmidt aspheric corrector lens), but with the addition of a dual-element multicoated field flattener lens installed in their central baffle tube. The field flattener is designed to reduce off-axis coma and produce aberration-free images across a wide visual and photographic field of view.

   In addition to reduced off-axis coma, the EdgeHD optical system delivers an astrograph-quality flat focal plane across the entire field. Many optical designs that advertise themselves as “astrograph” quality actually produce their pinpoint stars across a curved focal plane. While this may be acceptable for visual observing, stars appear out of focus at the edge of the field when used with the flat rectangular imaging sensor of a DSLR digital camera or a large format CCD. The built-in field flattener of the EdgeHD optical system produces a focal plane more than three times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than other competing coma-free designs. This guarantees visibly sharp stars across some of the largest CCD and DSLR chips available today.

   The superior edge performance of the EdgeHD optic system not only creates rounder, more point-like, and more pleasing stars at the edge of the field but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture. Poor edge quality or field curvature in conventional optics can spread out a star’s image at the edge of the field so much so that the brightness of a star appears the same as the sky background, making it undetectable to your eye (or camera). EdgeHD optics give you smaller (more concentrated) stars that create brighter images that pop out of the sky background, allowing you to see down to a fainter magnitude. This lets you capture fainter stars and galaxies out to the corners of your full frame camera chip than is possible with conventional telescope designs of equal aperture.

This Celestron CGEM DX 1400HD telescope has:

• 14” EdgeHD high definition aplanatic Schmidt-Cassegrain optics
• newly-upgraded 50 pound payload capacity CGEM DX German equatorial mount
• StarBright XLT optical multicoatings for the highest possible light transmission
• 9 x 50mm finderscope
• 23mm 2” 82° field Axiom eyepiece (170x) and 2” star diagonal
• NexStar go-to computer hand control with 40,000+ object database
• NexRemote software to control the telescope via computer
• 2-year warranty

   The Celestron CGEM DX 1400HD telescope puts unique new large aperture 14” aplanatic (free from coma and corrected for spherical aberration) EdgeHD high definition Schmidt optics on a newly-upgraded high-precision Celestron CGEM DX go-to German equatorial mount. The advanced EdgeHD optical design – a Sky & Telescope Hot Product for 2010 – has a dual-element field flattener lens made from premium Schott optical glass mounted in its central baffle tube. The field flattener reduces off-axis coma and produces aberration-free images across a wide 42mm image circle (as large as the diagonal of a 35mm negative or large format CCD chip and ideal for astrophotography).
In addition to reduced off-axis coma, the EdgeHD optical system delivers an astrograph-quality focal plane more than three times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. Stars are smaller and more concentrated, creating brighter images and allowing you to see down to a fainter magnitude than other equally-sized telescopes. You see visibly sharp and point-like stars to the very edges of some of the largest CCD and DSLR chips available today.
Celestron’s renowned Starbright XLT multicoatings on every optical surface give you maximum light throughput across the widest possible visual and photographic spectrum. The big aperture CGEM DX 1400HD’s immense light grasp, almost 1600 times that of even the sharpest dark-adapted eye, reveals star clusters, nebulas, planets, and galaxies in amazing visual and photographic detail. The Fastar-compatible optical tube allows imaging down to an incredibly-fast f/2 focal ratio using optional accessories.
The smooth and precise Celestron CGEM DX go-to mount makes finding over 40,000 of those stars and objects easy and automatic. You spend more time looking at celestial objects, and less time looking for them. The newly-upgraded CGEM DX mount combines portability and premium-level performance with a payload capacity of 50 pounds, enough capacity to handle the 45 pound 14” Celestron EdgeHD optical tube with assurance.
With a heaviest single component of only 45 pounds, the CGEM DX 1400HD is the lightest and most portable version ever of Celestron’s flagship 14” telescope. Its light weight individual components and easily assembled mount make it easy for one person to set up and enjoy – either in your back yard or at a distant dark sky site. Its superb flat-field reduced-coma optical quality and reasonable price for a really big full-featured computerized go-to mount make this Sky & Telescope Hot Product for 2010 winner Celestron CGEM DX 1400HD a telescope that will provide you with years of affordable and enjoyable observing.


This Telescope’s Optical System . . .

  • EdgeHD aplanatic Schmidt-Cassegrain optical tube: 14” aperture (3910mm focal length f/11). Guaranteed diffraction-limited optical performance, free from coma and corrected for spherical aberrations (aplanatic design). The optical design is a Sky & Telescope Hot Product for 2010. The 31” long aluminum optical tube has a large handle on the rear cell and weighs 45 pounds, making it a reasonable task to transport and assemble the scope in the field. For more details, click on the “EdgeHD optics” icon above.

  • Starbright XLT fully multicoated optics: This high transmission/high reflectivity optical coatings package gives you visibly higher light transmission for brighter deep space images and shorter exposure times during CCD and DSLR photography. It also increases the contrast on subtle lunar, planetary, and nebula details when compared with a scope with ordinary coatings or multicoatings. For more details, click on the “Starbright XLT” icon above.

  • Tube vents: Two cooling vents located on the rear cell allow warm air to be released from behind the primary mirror when the scope is taken out for a night’s observing or imaging. This shortens the amount of time needed for the optics to cool down to ambient air temperature for peak optical performance. Each vent has an integrated 60 micron micro-mesh filter guaranteed to let warm air out without letting dust in.

  • Fastar compatible: For the ultimate in wide-field catadioptric imaging, the EdgeHD optical tube is Fastar compatible to allow CCD imaging at a blazingly-fast f/2 focal ratio, although without the benefits of the dual-element field flattener built into the scope’s baffle tube. An optional Fastar lens assembly lens replaces the telescope’s removable secondary mirror (an exchange that takes only a few minutes). Your CCD camera is attached to the Fastar lens. This puts your camera at the f/2 position in the center of the Schmidt corrector lens at the front of the scope, rather than in its normal f/10 position at the Cassegrain focus at the rear of the scope.
    Using the Fastar system and a sub-$1300 Orion Star Shoot Deep Space Imager Pro CCD camera, the 14” CGE Pro 1400HD will record a wide 111 x 74 arc minute field – a long axis over three and one half times the diameter of the full Moon, an immense field for a scope of this size. To assure repeatability when you switch between Fastar and conventional imaging, the scope’s optical tube is opto-mechanically aligned on a laser bench during manufacture so that all components are axially symmetric in any configuration.

  • Focusing: Focusing is accomplished by turning a knob at the rear of the scope body that moves the primary mirror fore and aft along a central baffle tube to adjust the focus. The Celestron focusing mechanism is supported by two pre-loaded ball bearings, minimizing the “mirror flop” typical of bushing focus mechanisms that causes image shift during critical focusing.

  • Mirror locks: Flexible tension locks hold the mirror in place after correct focus is achieved for imaging and reduce image shift when rotating the tube around the mount (when moving past the zenith during astrophotography, for example). Unlike other designs that have only one locking knob located off to one side of the mirror, the Celestron system uses three locks equally spaced around the mirror to distribute the mirror locking force symmetrically. The focuser itself acts as one of the locks, while two flexible rods spaced 120° away in either direction act as the second and third locks. Controlled by variable tension knobs on the rear cell, these rods act in conjunction with the focuser to hold the mirror in place without putting any asymmetrical force or pressure on the mirror. This keeps the image centered in the eyepiece (or CCD chip) no matter what the orientation of the optical tube.

  • Finderscope: 9 x 50mm straight-through achromatic design, with a substantial 5.8° field of view, in a quick-release bracket.

  • Star diagonal: 2” first-surface mirror type, with 1.25” adapter.

  • Eyepiece: premium 2” 23mm 82° field Axiom (170x), a much higher quality eyepiece than those supplied with competitive scopes. The eyepiece field of view is over 0.48° wide, almost as wide as the full Moon, and an exceptionally wide field for 170x magnification.

This Telescope’s Mount . . .

  • Newly upgraded 50 lb. payload capacity heavy duty CGEM DX computerized German equatorial mount: The CGEM DX mount includes dual-axis slewing/tracking motors on each axis, with new drive electronics for go-to computer control. There are nine motor drive speeds: 0.5x and 1x sidereal for guiding; 4x, 8x, 16x, and 64x for centering; and 0.5°, 2°, and a fast 5° per second for slewing. Preset tracking rates include sidereal, solar, and lunar for precise tracking of celestial objects inside the solar system as well as out in deep space.

  • Powering the CGEM DX 1400HD : The CGEM DX mount comes with a car battery cord to operate from the cigarette lighter plug of your car or from a rechargeable 12VDC battery pack. The 17 amp hour capacity Celestron Power Tank #4517V is recommended and will operate the scope all night long without danger of running out of power. A 5 amp capacity AC adapter (#2338PRO) is also available for continuous operation from a household AC outlet, in an observatory dome, for example.

  • Polar alignment: To make a casual polar alignment for visual use quick and easy, there’s a latitude scale with large ergonomically-friendly altitude and azimuth adjustment knobs. No polar alignment finderscope is available to aid in the precise polar alignment required for long exposure astrophotography, nor is any needed. A unique Celestron All-Star Polar Alignment program built into the NexStar hand control helps you do a very precise computerized polar alignment in mere minutes, using any bright star, even when Polaris is hidden by trees or buildings. The program works in both northern and southern hemispheres.

  • Adjustable height tripod: The heavy and stable 45 pound tripod (the same one used on Celestron’s top-of-the-line CGE PRO mount) has 2.75” diameter stainless steel legs with a metal center leg brace for rigidity, for excellent vibration 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.

  • Mounting the scope: A Losmandy-style “D-plate” dovetail slot on the top of the mount holds the long dovetail slide bar mounted under the optical tube. This allows you to slide the optical tube fore and aft in the dovetail slot to quickly and precisely balance the optical tube in declination when you add or subtract accessories, 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. The oversized dovetail mounting platform assures secure vibration-free tube attachment.

  • Balancing the scope: Two sliding 22 pound counterweights are locked in place on the new larger diameter counterweight shaft with a single large hand-tighten knob each. This makes it easy to rebalance the scope in right ascension as you add and remove major accessories. A very heavy accessory load added to the 45 pound optical tube might push the scope’s 50 pound payload capacity, however. If considerable imaging with a consistently very heavy accessory load is planned (photoguide rings, guidescope, heavy CCD camera, filter wheel, etc.), it might be more prudent to move up to the CGE Pro mount version of this scope. While considerably more expensive than the CGEM DX version, the added stability of the CGE Pro’s 90 pound payload capacity would be welcome with a very heavy accessory load.

  • NexStar computer hand control: The supplied NexStar computer hand control has a built-in database of more than 40,000 stars and objects that it can find and track for you. These include the complete RNGC, Messier, Caldwell, IC, and Abell catalogs; selected SAO stars; the planets, the Moon, and others. The custom database lists of all the most famous deep-sky objects by name and catalog number; the most beautiful double, triple and quadruple stars; variable stars; non-planetary solar systems objects; and asterisms.

  • The NexStar display: All of the database and scope operation information is displayed on a double line, 16-character, liquid crystal display on the hand control. There are 19 fiber optic backlit LED buttons to make it easy for you to control the computer without affecting your dark-adapted vision. The NexStar hand control provides a constant and easily-visible illuminated right ascension and declination readout of the scopes position on the sky. This provides much greater accuracy than conventional (and hard to see at night) manual setting circles for star-hopping or locating objects by their celestial coordinates alone, should you want to observe the old-fashioned way without using the computer to find objects for you.

  • Some NexStar features: The software built into the NexStar hand control includes many, many features and programs discussed at greater length by clicking on the “NexStar CGEM” icon above. An RS-232 communication port on the hand control allows you to operate the telescope via a personal computer using the supplied RS-232 cable and NexRemote software CD-ROM. The hand control and motor control software is flash-upgradeable to allow you to download the latest product updates over the Internet to keep your CGEM mount always at the cutting edge of technology. An autoguider port is located on the electronic pier for guided, but unattended, long exposure astrophotography.

  • Aligning on the sky: Five different alignment methods are built into the NexStar computer – 2-star align, quick align, 1-star align, last alignment, and solar align – allowing you to choose a level of computer accuracy in automatically finding objects with which you are comfortable. Alignment is easily accomplished in only a few short minutes. You can be observing in less than 15 minutes after you first take the scope outdoors. There’s even a new and unique “All-Star” software-assisted alignment of the mount’s polar axis using a single bright star that will have you ready for imaging before it’s even dark enough to see the North Star. For more details, click on the “NexStar CGEM computer” icon above.

  • Two-year warranty: All Celestron go-to telescopes have a two-year warranty, double that of competitive go-to scopes.
Highest Useful Magnification:
This is the highest visual power a telescope can achieve before the image becomes too dim for useful observing (generally at about 50x to 60x per inch of telescope aperture). However, this power is very often unreachable due to turbulence in our atmosphere that makes the image too blurry and unstable to see any detail.

On nights of less-than-perfect seeing, medium to low power planetary, binary star, and globular cluster observing (at 25x to 30x per inch of aperture or less) is usually more enjoyable than fruitlessly attempting to push a telescope's magnification to its theoretical limits. Very high powers are generally best reserved for planetary observations and binary star splitting.

Small aperture telescopes can usually use more power per inch of aperture on any given night than larger telescopes, as they look through a smaller column of air and see less of the turbulence in our atmosphere. While some observers use up to 100x per inch of refractor aperture on Mars and Jupiter, the actual number of minutes they spend observing at such powers is small in relation to the number of hours they spend waiting for the atmosphere to stabilize enough for them to use such very high powers.
650x
Visual Limiting Magnitude:
This is the magnitude (or brightness) of the faintest star that can be seen with a telescope. The larger the number, the fainter the star that can be seen. An approximate formula for determining the visual limiting magnitude of a telescope is 7.5 + 5 log aperture (in cm).

This is the formula that we use with all of the telescopes we carry, so that our published specs will be consistent from aperture to aperture, from manufacturer to manufacturer. Some telescope makers may use other unspecified methods to determine the limiting magnitude, so their published figures may differ from ours.

Keep in mind that this formula does not take into account light loss within the scope, seeing conditions, the observer’s age (visual performance decreases as we get older), the telescope’s age (the reflectivity of telescope mirrors decreases as they get older), etc. The limiting magnitudes specified by manufacturers for their telescopes assume very dark skies, trained observers, and excellent atmospheric transparency – and are therefore rarely obtainable under average observing conditions. The photographic limiting magnitude is always greater than the visual (typically by two magnitudes).

15.3
Focal Length:
This is the length of the effective optical path of a telescopeor eyepiece (the distance from the main mirror or lens where the lightis gathered to the point where the prime focus image is formed). Focallength is typically expressed in millimeters.

The longer the focallength, the higher the magnification and the narrower the field of viewwith any given eyepiece. The shorter the focal length, the lower themagnification and the wider the field of view with the same eyepiece.

3910mm
Focal Ratio:
This is the ‘speed’ of a telescope’s optics, found by dividing the focal length by the aperture. The smaller the f/number, the lower the magnification, the wider the field, and the brighter the image with any given eyepiece or camera.

Fast f/4 to f/5 focal ratios are generally best for lower power wide field observing and deep space photography. Slow f/11 to f/15 focal ratios are usually better suited to higher power lunar, planetary, and binary star observing and high power photography. Medium f/6 to f/10 focal ratios work well with either.

An f/5 system can photograph a nebula or other faint extended deep space object in one-fourth the time of an f/10 system, but the image will be only one-half as large. Point sources, such as stars, are recorded based on the aperture, however, rather than the focal ratio – so that the larger the aperture, the fainter the star you can see or photograph, no matter what the focal ratio.

f/11
Resolution:
This is the ability of a telescope to separate closely-spaced binary stars into two distinct objects, measured in seconds of arc. One arc second equals 1/3600th of a degree and is about the width of a 25-cent coin at a distance of three miles! In essence, resolution is a measure of how much detail a telescope can reveal. The resolution values on our website are derived using the Dawes’ limit formula.

Dawes’ limit only applies to point sources of light (stars). Smaller separations can be resolved in extended objects, such as the planets. For example, Cassini’s Division in the rings of Saturn (0.5 arc seconds across), was discovered using a 2.5” telescope – which has a Dawes’ limit of 1.8 arc seconds!

The ability of a telescope to resolve to Dawes’ limit is usually much more affected by seeing conditions, by the difference in brightness between the binary star components, and by the observer’s visual acuity, than it is by the optical quality of the telescope.

0.32 arc seconds
Aperture:
This is the diameter of the light-gathering main mirror or objective lens of a telescope. In general, the larger the aperture, the better the resolution and the fainter the objects you can see.

EdgeHD
 
Based on Astronomy magazine’s telescope "report cards", scopes of this size and type generally perform as follows . . .
Terrestrial Observation:
Observing terrestrial objects (nature studies, birding, etc.) is usually possible only with refractor and catadioptric telescopes, and convenient only when the scope is on an altazimuth mount or photo tripod. Most reflectors cannot be used for terrestrial observing. Scopes with apertures under 5" to 6" are generally most useful for terrestrial observing due to atmospheric conditions (heat waves and mirage, dust, haze, etc.) that degrade the image quality in larger scopes. 
No
Lunar Observation:
Visual observation of the Moon is possible with any telescope. Larger aperture scopes will provide more detail than smaller scopes, thereby getting a higher score in this category, but may require an eyepiece filter to cut down the greater glare from the Moon's sunlit surface so small details can be seen more easily. Lunar observing is more rewarding when the Moon is waxing or waning as the changing sun angle casts constantly varying shadows to reveal craters and surface features by the hundreds.

Terrestrial Photography:
Photographing terrestrial objects (wildlife, scenery, etc.) is usually possible only with refractor and catadioptric telescopes, and convenient only when the scope is on an altazimuth mount or photo tripod. Most reflectors cannot be used for terrestrial photography. Scopes with focal ratios of f/10 and faster and apertures under 5" to 6" are generally the most useful for terrestrial photography due to atmospheric conditions (heat waves and mirage, dust, haze, etc.) that degrade the image quality in larger scopes.
No
Lunar Photography:
Photography of the Moon is possible with virtually any telescope, using a 35mm camera, DSLR, or CCD-based webcam (planetary imager). While an equatorial mount with a motor drive is not strictly essential, as the exposure times will be very short, such a mount would be helpful to improve image sharpness, particularly with webcam-type cameras that take a series of exposures over time and stack them together. Reflectors may require a Barlow lens to let the camera reach focus.
