    Jupiter as seen through the Celestron NexStar 8SE special-edition computerized telescope.

    The Nexstar 8 SE upholds Celestron's reputation for quality optics. When I use an 11mm Plossl eyepiece (almost 200x magnification) for example, I can easily see the Cassini Division in Saturn's rings. When I look at Jupiter, the pale orange color of Jupiter's famous Great Red Spot is visible, and I've even been able to identify the polar caps and spot dust storms on the planet Mars. A 20mm Plossl eyepiece (about 100x magnification) is a good choice for viewing galaxies and star clusters. When I look at globular cluster M13 in the constellation Hercules the high contrast XLT optics show me a glowing snowflake made of hundreds of tiny pin-point stars! And a low power 32mm Plossl eyepiece is a good choice for views of larger deep space highlights like the Andromeda Galaxy and the Orion Nebula.

    (See larger image.)

    Celestron's patented "SkyAlign" system makes the Nexstar 8 SE very easy to use. I just pick the nearest town from the built-in list, enter the date and time, and point the telescope at three bright stars. I don't need a star chart because "SkyAlign" identifies the stars for me. When I just want a quick look at the moon or a planet, I like to use the "Solar System Align" option. After entering the date and time, I just point the telescope at the moon and press the "Align" key. That's all it takes, the computer takes over and the telescope begins tracking quietly and accurately. At star parties I often have my Nexstar up and running while older computerized telescopes are still waiting for their alignment stars to appear in the twilight.

    The Nexstar 8 SE comes with a simple red-dot finder scope and a basic 25mm eyepiece. You'll want to add a few good eyepieces to take full advantage of the Nexstar 8 SE's excellent optics. At the very least get Celestron's bargain priced Accessory Kit which includes high and low power plossl eyepieces, or treat yourself to some top rated Tele Vue eyepieces. At twenty-four pounds total weight, the Nexstar 8 SE is unusually light and portable for an eight-inch telescope. The drawback of course is that some people will find it too light. Like other Schmidt Cassegrain (SCT) telescopes there are plenty of optional accessories to upgrade this telescope with, such as heavy duty tripods and an optical finder scope. If you want to try astro-photography, however, check out Celestron's CPC 800 Telescope which features a heavy duty mount and tripod and an 8x50 optical finder scope right out of the box. --Jeff Phillips

    Pros:

    • Excellent optics
    • Easy computerized GoTo tracking
    • Light, portable and affordable
    Cons:
    • Plastic accessories
    • Short battery life
    • Too light for astro-photography

The standard equipment tripod and mount feature easy no-tool setup, and the package even includes a student version of "The Sky" planetarium software for your computer.

    The excellent optics of Celestron's classic C5 Schmidt-Cassegrain telescope have been updated with premium Starbright XLT optical coatings. This telescope consistently delivers crisp, high contrast views of the moon, the planets, and brighter deep space objects. The standard equipment 25mm plossl eyepiece produces a magnification of 50x, powerful enough to show the rings of Saturn, the cloud bands of Jupiter, and the changing face of the Lunar disk. Optional eyepieces can be added to bring out significantly more detail. I like to use a 12.5mm plossl (100x magnification) or a 7.5mm Ultrascopic eyepiece (166x) for high power views of the planets. With the 7.5mm Ultrascopic eyepiece I can usually see the Cassini Division in Saturn's rings and cloud bands on the planet itself. I like to use a 32mm plossl eyepiece for great low power views of deep space highlights like the Orion Nebula or the Double Cluster in Perseus.

    The NexStar 5 SE package also includes a sturdy adjustable tripod, a motorized alt-azimuth mount, and the NexStar hand held computer controller. You won't need a GPS receiver or star charts to operate this telescope. The SkyAlign procedure is easy to use, and experienced observers 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 5 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 telescope, of course, is battery consumption. I like to use a rechargeable Celestron Power Tank because the standard AA alkaline batteries only last a few hours.

    This telescope is perfect for visual observing, and allowed me to capture some sweet images of the moon and planets using a Celestron NexImage web-cam. For long exposure deep space photography, however, I'd take a look at Celestron's Advanced Series equatorial telescopes such as the C6 N-GT --Jeff Phillips

    • Computerized hand control with 4,000-object database
    • SkyAlign allows you to align on any 3 bright celestial objects
    • Motorized Altazimuth mount
    • Focal ratio: f5
    • Focal length: 650mm

    Celestron NexStar 130 SLT Series Newtonian Reflector Telescope - 31145Amazon.com Celestron’s computerized NexStar 130 SLT adds affordable "Go-To" technology to a compact Newtonian reflector telescope. By using mirrors instead of lenses, the Newtonian optics of the NexStar 130 SLT produce an image nearly five times brighter than the NexStar 60 SLT refractor telescope. The package includes everything except the batteries, and features easy no-tool setup, two good eyepieces, and even includes a student version of "The Sky" planetarium software.

    The Newtonian design of the NexStar 130 SLT is optimized to produce bright images over a wide field of view. When I use an optional 32mm Plossl eyepiece, the famous Double Cluster in Perseus looks like a display of celestial fireworks with streamers of stars trailing across the 2 degree field of view. The standard equipment 25mm eyepiece magnifies the image about 26 times, with a wide field of view just right for viewing deep space objects like star clusters or the Orion Nebula.

    Celestron NexStar 130
    The included 9mm eyepiece (72x magnification) offers great views of the Lunar disk and globular star clusters like M13. And when I add a 2x Barlow lens to the 9mm eyepiece for a total magnification of 144x, I can easily see cloud bands on the planet Jupiter and pick up detail in Saturn’s rings.

    The NexStar 130 SLT also features Celestron’s patented SkyAlign technology. With SkyAlign I don't need a star chart or a compass to align the telescope, I just enter the date and time then point the telescope at three bright stars. SkyAlign tells me the star names, and allows the telescope to find over 4,000 stars, planets, and galaxies by just pushing a button. The accurate tracking makes it easy to get high power views of the planets, and allowed me to take some great pictures using a Celestron NexImage webcam. I also like the "Two-Star align" and "Solar System align" modes because I can often get the NexStar system up and running while older scopes are still waiting for their alignment stars to appear in he twilight.

    Reflector telescopes offer more light gathering power per dollar than any other design, but that value is balanced by the fact that the mirrors may need to be aligned or "collimated" occasionally. Using Celestron’s Collimation Eyepiece

    Celestron NexStar 130
    I had no trouble fine tuning the optical alignment, and I was rewarded with sharp views of Lunar craters even when I pushed the magnification up to the theoretical limit of 300x. The other drawback of a computerized telescope, of course, is battery consumption. An optional PowerTank battery is a handy way to power the NexStar 130 SLT, and I like to keep the tripod legs short and observe while seated because this gives me a solid and comfortable view. --Jeff Phillips

    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.

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

Most NexStar SLT’s can also be used as a land-based spotting telescope. Celestron's NexStar 90 SLT is the most compact telescope in Celestron's computerized NexStar line, with excellent Maksutov-Cassegrain optics that deliver delightful views of the Moon and planets. The NexStar 90 SLT package includes everything but the batteries. With a fully illustrated quick set-up guide, no tools are needed to assemble the telescope with its steel tripod, motorized mount, and computer hand control. Two eyepieces are included, a 25mm for 50X magnification and a 9mm eyepiece for 139X. The package even includes the latest version of "The Sky X", software that turns your PC into a virtual planetarium.

    The Maksutov optical design of the NexStar 90 SLT gives the telescope a focal length of 1250mm in an optical tube only twelve inches long. This long focal length is ideal for bringing out detail on the Moon and planets. When I look at the Moon for example, the view is crisp and clear with no trace of false color. When I look at Saturn I can easily push the magnification to 200X with an optional 6mm plossl eyepiece. When I look at deep space objects I often like to use an optional 32mm plossl eyepiece (39X magnification) because objects like M45 the Pleiades cluster and M31 the Andromeda galaxy look better with a wider field of view.

    The NexStar 90 SLT also features Celestron's patented SkyAlign technology. With SkyAlign I don't need a star chart or a compass to align the telescope, I just enter the date and time then point the telescope at three bright stars.

    I enjoy using the NexStar 90SLT because it has excellent optics in a compact, twelve pound package that I can carry outside in one trip and be ready to go in minutes. A computerized telescope may take practice to set up; if I don't enter the time correctly the alignment may fail for example. The other drawback of a computerized telescope, of course, is the short life of standard AA batteries. A rechargeable 12-Volt battery is a handy way to power the NexStar 90SLT, and I like to keep the tripod legs short and observe while seated because this gives me a solid and comfortable view. --Jeff Phillips
