Get the same star locating technology found on our observatory-grade telescopes at a price that fits your family’s budget with the 114LCM.
Locates objects for you
Leave the star maps at home; 114 LCM computerized telescopes can locate thousands of celestial objects for you automatically. To get started, just perform our simple SkyAlign alignment procedure by centering any three bright objects in your telescope’s eyepiece. From there, your LCM can calculate the time, date, and location and orient itself with the night sky.
Browse the hand control’s database and select any star, planet, galaxy, or nebulae in the database. Within seconds, your LCM centers it in the eyepiece and tracks it as it moves across the sky. Looking for something new to observe? Press the Sky Tour button and your LCM generates a list of the best celestial objects currently visible.
Precision optics for detailed views
With the largest optics in the LCM beginner telescope family, the 114LCM packs enough light-gathering ability to provide extraordinary views of all the best celestial objects. Explore our Solar System, from the moons of Jupiter to the rings of Saturn and beyond. Then venture further into deep space to view the Orion Nebula, Pleiades Star Cluster, and hundreds of other objects. You can even explore the craters of the Moon up close, with impressive detail.
Everything you need to get started
Even if you’ve never used a telescope before, Celestron makes it easy to get started with amateur astronomy. Your LCM telescope comes with an adjustable aluminum tripod, 2 high quality eyepieces, and a red dot finderscope. Plus, everything is backed by Celestron’s 2-year warranty.
To enhance your experience under the stars, download Celestron’s free SkyPortal app. Listen to hundreds of audio descriptions of the most popular objects on your iOS or Android device while you observe them with your LCM telescope.

THE SMARTEST TELESCOPE IN THE UNIVERSE!
A truly revolutionary product with ground breaking technology, SkyProdigy™ is the product of a culmination of decades of telescope advancements. It combines electronic motors, an intelligent on-board computer, a digital camera and StarSense™ technology to create an automatic, instant alignment telescope that requires no input from the user. Simply turn it on, push a button and enjoy the view! It’s that easy.
The SkyProdigy’s automatic alignment process takes only a few minutes, then you will be ready to select from thousands of objects to view. Not sure what to look at? Select the Sky Tour option; this feature offers a customized list of the best objects in the sky to view for your exact time and location anywhere in the world!
NO KNOWLEDGE OF THE NIGHT SKY IS REQUIRED. ONE TOUCH INNOVATION TURNS ANYONE INTO AN INSTANT ASTRONOMER!
Celestron’s SkyProdigy telescopes use an integrated imaging camera and patented StarSense Technology to automatically align with the night sky and determine where the telescope is currently pointing. The camera automatically captures an image of the sky, which is processed internally to positively identify the stars in the image. Once a positive match is found, SkyProdigy determines the coordinates of the center of the captured image. The process is automatically repeated two more times so that the system has three known alignment points that can be used to make an accurate model of the night sky. From this information the user can select any celestial object in the hand controller’s database, and SkyProdigy will automatically move itself to the correct position.
*THE SKYPRODIGY’S INTERNAL CAMERA DOES NOT HAVE AN EXTERNAL OUTPUT ALLOWING USERS TO VIEW OR SAVE THE CAPTURED IMAGES. THE CAPTURED IMAGES ARE USED INTERNALLY SOLELY FOR THE PURPOSE OF SELF-ALIGNING THE SKYPRODIGY TELESCOPE.

SW EvoStar 100ED APO Refractor: When You Demand the Best!
Sky-Watcher is a leader in the design and manufacturer of ED-APO systems. Sky-Watcher offers one of the most extensive lines of ED-APOCHROMATIC refractors in the world. Using only the finest fabrication materials available, Sky-Watcher APO refractors are manufactured to painstakingly rigorous, exacting standards of optical and mechanical quality to insure the amateur astronomer peak performance and a great experience each and every time a Sky-Watcher ED-APO is taken into the field. We know the amateur astronomer has very high expectations regarding astronomical equipment purchases. Sky-Watcher has been delivering consistent satisfaction for decades. This telescope is designed for a lifetime of astronomical enjoyment!
Observing with the Sky-Watcher EvoStar 100ED 100mm Refractor
Turning the telescope to the first quarter Moon, the Apennine Mountains snap into focus revealing a cornucopia of jagged mountain ridges, canyons, and numerous small craters in razor-sharp detail. Not far removed, reaching skyward the crater wall of Archimedes pops into view in bold relief against the smooth flatlands that transverse the distance between it and the Apennine Mountains. This is lunar observing at its best – HD style. The gas giant Jupiter displays its swirling equatorial bands in high-definition with festoons, and tonality within the bands. The great spot is clearly visible, discreetly contrasted from the surrounding Jovian landscape. Saturn’s storied surface phenomenon is simply stunning. Hunt down double stars like Epsilon Lyrae, the “double-double" in Lyra. A 100mm refractor will provide a crisp well defined image superior to even a larger reflector. Always a star-party favorite, Alberio located in the tail of Cygnus never fails to please as it is a beautiful double. Alberio appears like a gold sparkler and its companion looks blue-green. It is a perfect refractor object. Compact globular star clusters lend themselves well to a refractor. Located outside our galaxy the globular M2 will probably resolve more stars in a 4" refractor than a 6" reflector. M4, M10 and many other globular cluster can be seen well with a 100mm refractor. M13, the fantastic globular in Hercules is a stunning sight in a 100mm refractor. The bright central cores of prominent nebulae can be seen and the brightest stars can be resolved. This is just the beginning of an incredible journey of exploration possible with a SW ED-APO 100mm refractor. As an astrograph, the SW EvoStar 100ED APO performs superbly delivering crisp, high-fidelity imaging of planetary, lunar and aperture appropriate deep-space phenomenon.
Refractors—the Ultimate Imaging Instruments
In a given aperture size, refractors will always exhibit sharper images than other optical designs because the refractor concentrates more light into the central airy-disk and first diffraction rings. There is no diffraction pattern interference caused by a diagonal mirror, or secondary mirror being suspended in the optical path (central obstruction) as is the case with reflectors.
Sky-Watcher ED-APOs—the Ultimate Refractors
Sky-Watcher ED-APO refractors provide the finest images obtainable—bar none—in their design class. If you are on a quest for the ultimate in pristine, near textbook-perfect astronomical imaging, look no further! Sky-Watcher ED apochromatic refractors deliver dramatic coal-back skies and faithful, contrast-rich views of planetary and deep-space phenomenon that are second to none. Sky-Watcher ED-APO refractors are the logical choice as an investment in advanced instrumentation for exceptional viewing or photography.
Virtually Eliminates Residual Chromatic Aberration
The Sky-Watcher ED-APO design assures virtual elimination of residual “false color" (i.e. chromatic aberration) normally present in 2-element achromatic lens designs which utilize standard crown and flint glasses. Sky-Watcher APO refractors utilize the finest extra-low dispersion (ED) glass available, FPL-53. This results in the best color correction for an ED doublet lens.
Schott Glass Used in Selected Models for Crown Element
Select models of ED-APO refractors will benefit from the inclusion of Schott glass being used for the positive front Crown element in the objective. Schott is the recognized world leader in glass utilized for precision optical lens systems, including medical instrumentation, and famous-brand camera lenses. While Schott glass is only used in selected models, all other models utilize top-quality, Grade-A glass from perhaps less famous but, nonetheless, highly respected, high-quality glass manufacturers.
Pride and Perfection in Optical Manufacturing
Every lens element is individually inspected for purity and absence of striae and other image-degrading imperfections. Every lens is pitched polished to exacting standards of optical fabrication and performance by highly skilled opticians utilizing state-of-the-art methodology and rigidly controlled optical testing procedures. The result is high-quality, diffraction-limited optics performing to the theoretical limits of their respective aperture sizes. All lenses are uniformly air-spaced in their cell housings.
Metallic High-Transmission Lens Coatings
Each air-to-glass lens surface has exotic anti-reflection metallic coatings applied to ensure optimum light through-put. The proprietary Sky-Watcher “Metallic High-Transmission Coatings" (MHC) are the finest photon anti-rejection coatings in their class.
Light-Baffled Optical Systems
The objective lens cell is light-baffled to reject stray, unfocused light. The draw tube is likewise baffled to insure optimum contrast. The tube interior is flat blackened to help prevent unfocused internal light reflections from reaching the focal plane.
Precision 2" Crayford-style Focuser is Standard
Optical focus is achieved by means of a mechanically ultra-smooth, backlash-free, precision 2" Crayford-style focuser-assembly with 1.25 adaptor. This focuser operates at 2 speeds for fine and ultra-fine focusing adjustments.
Tube Materials
The optical tube material is aluminum, powder-coated reflective gloss black with gold fleck accent. The front and back cells are cast-aluminum painted white, or black.
Telescope Tube Attachment Hardware
The Sky-Watcher APO optical tubes come with attachment hardware that allows them to be securely fastened to compatible mounts. The quick-release tube rings provided with SW ED-APO models 80ED, 100ED and 120ED are cast-aluminum, painted white.
Included Components for Selected Models
All Sky-Watcher USA EvoStars come with 2-speed backlash-free 2” Crayford-style focusers and quality foam-lined metal carrying cases as standard equipment. EvoStars are also supplied with right-angle 8x50mm viewfinder with bracket; 2” dielectric diagonal; two 1.25” LE (Long Eye relief) eyepieces (LET20mm and LET5mm); 1.25” focuser adaptor; and tube ring attachment hardware that works with compatible mounts.

SKY-WATCHER EvoStar 120ED APO REFRACTOR: Serious Amateurs will Love the SW 120mm ED-APO Refractor
Sky-Watcher high-performance ED-APO refractors offer premium optical performance for the discriminating amateur astronomer. Refractors are coveted for their superb contrast, high-definition and coal-black sky background that make stars appear like diamonds embedded in black velvet. SW APO refractors utilize the most modern optical glasses and fabricating techniques to deliver the ultimate in high-fidelity astronomical imaging. Subtle details pop as never seen before in telescopes of lesser optical capability.
Observing with the Sky-Watcher EvoStar 120ED APO Refractor
The additional aperture compared to a 100 mm diameter lens provides a dramatic increase in resolution and a heighten sense of seeing lunar and planetary surface phenomenon in seemingly 3D high-definition.
Touring the Moon…the rugged Southern Highlands of the lunar surface are rich in craters. To the southeast, the famous crater Theophilus is 65 miles across. The raised triple-peaked central area is striking to observe in your SW 120ED. The crater has massive walls and the basin is 14,000 feet deep. One of the southernmost craters, Clavius, is a very large crater 145 miles across. It is located south of Tycho. In this same area can be found craters Maginus and Longomotanus which are also very worthy of exploration. To the north, the young crater Tycho dominates the southern lunar landscape. Named after the famous Danish astronomer Tycho Brahe, it is a spectacular sight with very high-rimmed walls. Your SW120ED will provide an impressive view. North of Tycho appearing brightly in a basin is the famous Rupes Recta (the Straight Wall), an 800 foot mountain that is a “must see” for amateur astronomers. Your SW 120ED will show it clearly and sharply the way you want to see it. On the north end of Mare Nubium, almost on the lunar N-S and E-W center line can be found 3 craters grouped together: Arzachel a young impact crater 60 miles across and 13,000 feet deep shows a terraced structure and a system of channel-like narrow depressions in its basin called “rilles”. Nearby are Alphonsus, a 70 mile wide crater, and Ptolemaus a prominent ancient crater 90 miles across with a heavily worn dark interior. The Earth’s Moon offers a treasure trove of fascinating detail to explore with your SW 120ED-APO EQ5 PRO. We have only featured a relative few examples of what is available. The views you will experience are so clear and sharp it might just feel like a veritable space-walk.
Planets are spectacular…the inner solar-system presents the colorful rusty-red planet Mars. Mars is a challenge for amateur astronomers, but your SW 120ED will show some very interesting detail. Olympus Mons, a volcanic crater 375-miles across and 16-miles high, is just one of the quests your capable SW120ED can tackle. Nirgal Vallis is a channel 600 miles long that responds well to the razor sharp contrast provided by the SW 120ED. The Grand Canyon of Mars, Valles Mariners, dwarfs that of our Earth’s Grand Canyon, but it still requires superb optics to view even though it is 150 miles wide and 4 miles deep. When prominent, the gleaming white Mars’ polar cap is in stark contrast to the redish-orange surface landscape of the rest of the planet. The SW 120ED will show you this detail like you want to see it. The gas giant Jupiter displays its swirling equatorial bands in high-definition with festoons and tonality within the bands. With regular observation, you will be able to follow storms and disturbances cross the planet in the southern equatorial band. Saturn’s storied surface phenomenon is simply stunning. View the rings and clearly see Cassini’s Division and cloud belts across its equator.
View Wonders of Deep-Space…beyond the solar-system hunt down double stars like Epsilon Lyrae, and the “double-double” in Lyra. A 120 mm ED-APO refractor will provide a crisp well defined image on par with up to a 7″ reflector. Always a star-party favorite, the beautiful double Alberio located in the tail of Cygnus is sensational. Alberio appears like a gold sparkler and its companion looks like a blue-green sparkler. It is a perfect object to view with your SW 120ED. Algol, an eclipsing variable star, sometimes called the “winking eye” fluctuates in brightness and is a suitable subject for the SW 120ED. Aldebaran, a beautiful orange giant in the Constellation Taurus is a delightful sight to view with the SW 120ED. In the eastern corner of Constellation Orion, Rigel, a bright blue double has a blue-green companion that requires excellent optics to see, a worthy subject for the SW 120ED. Tight globular star clusters like M13 in the Constellation Hercules appear like a beehive of crisp stellar pin points circling the central core, star upon thousands of stars. Compact globular star clusters lend themselves well to a refractor. M5 is a worthy object for viewing. M92, in the Constellation Hercules, is very compact globular with a bright core. It is a great object to view with the SW 120ED. M4, M10 and many other globular clusters can be seen well with the SW 120ED-APO refractor. The bright central cores of prominent nebulae can be seen and the brightest stars can be observed illuminating the glowing nebulosity which appears as ghostly apparitions.
The superb capabilities of the SW 120ED provide performance on a par with a reflector of perhaps up to 7″ in diameter on lunar, planetary, double-stars, globular star clusters, and depending on your ranking of unobstructed high-contrast as a necessary attribute, even the brighter nebulae may look better to you in a SW 120ED. These objects will stand out in bold relief contrasted against a very dark velvet-black sky background. Many advanced amateur astronomers feel the ED-APO experience is astronomy’s richest.
As an astrograph, the SW EvoStar 120ED APO performs superbly delivering crisp, high-fidelity imaging of planetary, lunar and aperture appropriate deep-space phenomenon.

In a given aperture size, refractors will always exhibit sharper images than other optical designs because the refractor concentrates more light into the central airy-disk and first diffraction rings. There is no diffraction pattern interference caused by a diagonal mirror or secondary mirror being suspended in the optical path (central obstruction) as is the case with reflectors.
Sky-Watcher ED-APOs – the Ultimate Refractors
Sky-Watcher ED-APO refractors provide the finest images obtainable – bar none – in their design class. If you are on a quest for the ultimate in pristine, near textbook-perfect astronomical imaging, look no further! Sky-Watcher ED apochromatic refractors deliver dramatic coal-black skies and faithful, contrast-rich views of planetary and deep-space phenomenon that are second to none. Sky-Watcher ED-APO refractors are the logical choice as an investment in advanced instrumentation for exceptional viewing or photography.
Virtually Eliminates Residual Chromatic Aberration
The Sky-Watcher ED-APO design assures virtual elimination of residual “false color” (i.e. chromatic aberration) normally present in 2-element achromatic lens designs which utilize standard crown and flint glasses.
Sky-Watcher APO refractors utilize the finest extra-low dispersion (ED) glass available, FPL-53. This results in the best color correction for an ED doublet lens.
Schott Glass Used in Selected Models for Crown Element
Select models of ED-APO refractors will benefit from the inclusion of Schott glass being used for the positive front Crown element in the objective. Schott is the recognized world leader in glass utilized for precision optical lens systems, including medical instrumentation and famous-brand camera lenses. While Schott glass is only used in selected models, all other models utilize top-quality, Grade-A glass from perhaps less famous but, nonetheless, highly respected, high-quality glass manufacturers.
Pride and Perfection in Optical Manufacturing
Every lens element is individually inspected for purity and absence of striae and other image-degrading imperfections. Every lens is pitched polished to exacting standards of optical fabrication and performance by highly skilled opticians utilizing state-of-the-art methodology and rigidly controlled optical testing procedures. The result is high-quality, diffraction-limited optics performing to the theoretical limits of their respective aperture sizes. All lenses are uniformly air-spaced in their cell housings.
Sky-Watcher offers one of the most extensive lines of ED-APOCHROMATIC refractors in the world. Using only the finest fabrication materials available, Sky-Watcher APO refractors are manufactured to painstakingly rigorous, exacting standards of optical and mechanical quality to insure the amateur astronomer peak performance and a great experience each and every time a Sky-Watcher ED-APO is taken into the field. We know the amateur astronomer has very high expectations regarding astronomical equipment purchases. Sky-Watcher has been delivering consistent satisfaction for over a decade.
Metallic High-Transmission Lens Coatings
Each air-to-glass lens surface has exotic anti-reflection metallic coatings applied to ensure optimum light through-put. The proprietary Sky-Watcher “Metallic High-Transmission Coatings” (MHC) are the finest photon anti-rejection coatings in their class.
Light-Baffled Optical Systems
The objective lens cell is light-baffled to reject stray, unfocused light. The draw tube is likewise baffled to insure optimum contrast. The tube interior is flat blackened to help prevent unfocused internal light reflections from reaching the focal plane.
Precision 2″ Crayford-style Focuser is Standard

Sky-Watcher EvoStar 80ED APO Refractor: Portable Optical Powerhouse!
Due to their unobstructed textbook-like diffraction patterns and exotic optical properties, the ED-APO produces the sharpest, highest quality imaging obtainable from any telescope optical design. These breathtakingly pristine celestial views are coveted by experienced amateur astronomers.
Observing with SW EvoStar 80ED 80 mm Refractor
Fortunate indeed is the amateur astronomer with a SW ED-APO 80 mm refractor on a clear night with transparent skies and a stable atmosphere. The Sky-Watcher ED-APO 80mm is a modestly wide-field telescope offering bright, wide swaths of sky in a single view. It is well suited for wide-field astronomical observation of prominent nebulae, star clusters and galaxies from a dark-sky location, or can be used as an astrograph for sky photography. As a terrestrial spotting scope or telephoto lens, the ED-APO’s performance is absolutely superb. Ultra high contrast allows the subtlest of details to be easily scrutinized under conditions of good seeing. The petite silhouette of the SW ED-APO 80 mm makes for an excellent compact, portable telescope that travels light and fits a small space. At about 50-power, structural detail becomes apparent in our solar system’s gas giants like Saturn and Jupiter. The Moon also exhibits striking crater detail along the lunar terminator.
