Amazon.com Review Celestron’s NexStar 4 SE is the smallest and most portable telescope in Celestron’s NexStar SE series. Using a Maksutov-Cassegrain optical design, the NexStar 4 SE puts the magnifying power of a four foot long telescope into an optical tube only 13 inches long.

The NexStar 4 SE features computerized finding and tracking of nearly 40,000 celestial objects, no-tool setup is easy, and planetarium software for your PC is included.
Celestron NexStar 4

The NexStar 4 SE delivers great views of the Moon, the planets, and bright deep space objects. The standard equipment 25mm E-Lux plossl eyepiece gives a magnification of 53X, enough to see the Lunar disk, Saturn’s rings and the major cloud bands on Jupiter. It’s easy to add optional eyepieces to zoom in for more detail. Using a 12.5mm X-Cel eyepiece for 106X magnification I can see several cloud bands on Jupiter and I can even pick out the small dark shadow as one of Jupiter’s moons passes in front of the planet. On a good night I can push the magnification up to 230X with a 6mm plossl eyepiece while viewing the Moon and planets.

The NexStar 4 SE package also includes a sturdy adjustable tripod, a motorized alt-azimuth mount, and the NexStar hand held computer controller. I don’t need star charts or a GPS reciever to operate this telescope. Celestron’s patented SkyAlign procedure is easy to use, and experienced users will like the two-star align and solar-system align options because they are even quicker to set up. The steel tripod and alt-azimuth mount provide a solid base for the NexStar 4 SE. Vibration is not a problem, even while focusing at high power. The computerized tracking is also very good, easily keeping planets in the field of a high power eyepiece. The disadvantage of a computerized scope, of course, is battery consumption. I find that rechargeable NiMH batteries work very well in the NexStar 4SE; a set of batteries lasts all evening and I don’t need to worry about electrical cords getting tangled in the dark.

The NexStar 4 SE is a great portable telescope, just right for visual observing or for taking short exposure pictures of the Moon and planets. It’s only fair to warn you that a small telescope has its drawbacks, however; there are thousands of objects in the NexStar database that are simply too dim to see with a four inch telescope. --Jeff Phillips

The Celestron Nexstar 6se Telescope is fun, big and heavy, powerful, and really good optics. The night I first used it I used the Skyalign alignment and worked perfectly along with auto 2 star alignment. That night I saw Saturn In really good detail, and what was surprising was I was able to see Swan Nebula and Hercules Cluster all from a heavy light polluted sky.

Optics: 10/10

Goto: 8/10

Tracking: 8:10

Portability: 7/10

Eyepiece: 7/10

Battery Life: 4/10

Strength of tripod: 10/10

Magnification: 10/10

Light Gathering: 9/10

So this telescope is really cool and fun to use and I will buy an AC adapter later. This telescope is the best I have Ever Had and Is worth the $800.00

Update 11/30/13:

I live in a very heavy light polluted sky and no deep sky objects are visible to the naked eye. But when I look through the telescope I see the Orion Nebula(M42) very bright and clear. But when I type in Dumbbell Nebula(M27) I don't see a thing except several tens of stars. To see it you have to image it, I took 10 images 10 second exposure each (10x10s) and stacked them for a total of 100 second exposure . The Nebula was big, bright, and colorful(you can see the image in the product image gallery). So to see brighter/faint deep sky objects in a light polluted sky you have to image them with a camera. the faintest thing I have ever detected in any image is about magnitude 12(244 times fainter you can ever see with the naked eye).

The five stars represent my opinion about the scope. I'm a novice at astronomy, so I can't really make any comparisons. I can tell you, however, that this scope does everything I've ever read about it. I pulled it out of the box and put it together and it went to work just the way the book said. I've done some solar viewing and a little digital astrophotography. My major purpose for this scope is in the area of deep-sky astrophotography without spending multiple thousands of bucks. It may be a little overkill for a novice like myself, but I wanted a scope that I wouldn't outgrow, and one that is easy to accessorize. The only thing I can nit-pick on this scope is the motor drives on the mount. They work fine, but they make a little too much noise, and the sound indicates to me that the gear train is not high quality components. It does seem to run very smooth, though! And accurate, every time! If YOU take the time to accurately set it up and aim it, then IT will put what ever you ask for right in the middle of your field of view. The battery holder is a little tight on the 2000mah NiMH AA batteries that I bought for it, but since I plan to use the AC adapter I bought for it, that's not really a big problem. I wish Celestron had designed the bubble-level INTO the base of the mount rather than just leave it loose for the user to install with the double stick tape on it's bottom. I bought a larger level from an RV store and epoxied it to the top of the battery cover. It seems to be very accurate and my alignment seems to work every time. I recommend a good variety of eyepiece filters, a solar filter for the main aperture, a 45deg. upright diagonal, and several eyepieces to cover the range from about 4mm to 32mm.Read more ›

We used our scope for the first time recently. I had read the manual and a lot of online materials before we received our scope so I was somewhat familiar with how to use it. I input our location using our place's longiture and latitude and used the unit's "two star" alignment setting since I could only make out two bright stars in our light-polluted location (Tokyo, Japan). After this, I input "Jupiter" into the hand controller and the scope slewed to the planet and placed it right in the center of the eyepiece's field of view. My family and I spent the next hour letting the scope swing around to various stars and binary systems that I couldn't see with my unaided eyes but showed up beautifully in the eyepiece. I recommend taking a look at Albireo in the list of "named stars" on the hand controller very highly.

I knew that a telescope, much like a camera, is a device that needs accessories. Therefore, before I bought the scope I purchased (used) a 9mm ocular, a barlow lens, a better star diagonal and a battery pack to power this thing. The car battery adapter I purchased with the scope. A lot of people don't use a case so I can understand why Celestron didn't include one with this to keep the price down. One of those plastic storage boxes should work well if you use the foam that comes with the scope to keep it in place.

The optics of the telescope and the special coatings on the optics are a great improvement over what I experienced 20 years ago with my first 5" SCT scope. The images are sharp and this scope is suitable for both planetary viewing and deep space objects. However, the deep space objects will require you to find a dark site to be really visable. Our first night of viewing included a look at M13, a globular cluster.
