 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.  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-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  Optical focus is achieved by means of a mechanically ultra-smooth, backlash-free, precision 2" Crayford-style focuser-assembly. This focuser offers 2-speed 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.

very good optics and overall design,  for imaging or guiding.

Good scope

This is a great little starter OTA for astrophotography and seeing as well. You'll need the field flattener for astrophotography, but well worth it.

A great OTA

Scope has long focus only attainable with extension tubes (not provided). 
Can't plop in an eyepiece or attach camera without accesories.
Has no instructions on how to use. Customer service advice: "It's only an Optical Tube Assembly."
I can't comment on optics.
Scope is nicely made and looks great!.

Needs Attachments To Use

The manual for this item can easily be found on the manufacturer's website.

I love the quality build on the scope, unfortunately I still haven?t used it outside yet. But it looks awesome

Sky Watcher evostar 120 ED

The Skywatcher EvoStar 80Ed is a great scope for the money.  Views are excellent using the supplied 20mm and 5mm eyepieces.  I was unsure how the scope would respond using the 5mm eyepiece, and was pleasantly surprised that the views with this ocular were sharp and crisp.  

Criticisms of doublets are based on the tendency of these scopes to provide green or purple fringing around the edges of bright objects.  With the 20mm eyepiece, I was able to discern minor green fringing around the waxing moon (about 3/4 full), but it was barely noticeable and did not detract from the views.

I mounted the scope on my Celestron AVX mount, which proved to be very steady.  On my first night with the scope, I viewed several galaxies, double stars, globular and open clusters, as well as the Moon, Jupiter, Mars, Venus and Saturn.  All the views were tack sharp and pleasant.

All together, a great scope.

Great wide field refractor

Excellent telescope relation cost/benefit.   All accesories included.  Its like "plug&play".  I´m an amateur astrophotographer.   I only use it for astrophotography, not for terrestrial view.  Excellent and sharp images.  First time to use and boy  an APO ED.  I´m sure you are going to enjoy  it.
Highly recommended.

Awesome telescope

The scope looked good. Unfortunately, the manual was missing. I searched on line for one but I was unsuccessfully.

No Manual Included

I'm a bit of a scope junkie and have owned many. Tend to buy scopes, use them for a while and then give them away. This scope is a keeper! Great wide field views of brighter objects. Optics are fantastic. 

Mounted scope on Celestron CG-4 Equatorial Tripod. The Right Ascension knob at some stiction when I first used the scope but a little spray of silicone lubricant fixed that.

I also added a Tel-Rad for easier target pointing. 

A very capable APO Refractor that will provide very satisfying views with the Wow Factor!
