Adjustable height tripod Celestron 2-Year Warranty 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. 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 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 Pros: Wide field views Computerized go-to tracking Light and portable Cons: Short battery life Sensitive to vibration Suggested Options: Celestron Accessory Kit Celestron PowerTank battery Celestron Collimation Eyepiece.

Celestron likes to say, "the only simple thing about NexStar is its operation," and we have to agree. The sophisticated NexStar 114 GT is quite easy to assemble, even for a complete novice. Once you put the scope together and mount it on the sturdy aluminum tripod (also included), simply take the hand control with illuminated dual 16-character LCD display, and dial in the date, location, and position of north. Using its quiet, high-precision servo motor, the NexStar automatically aligns itself with the night sky. Reflectors     This is a reflector telescope. Reflectors (also known as Newtonian reflectors or catoptrics) capture light with a mirror at the bottom of a tube, which sends the image to the eyepiece at the top of the tube.    First-time telescope users sometimes have difficulty with the idea of looking through the side of a telescope, but the big draw for reflectors is that they are by far the cheapest to manufacture-and thus offer the best value-of all telescope types. They also generally have zero chromatic aberration.    Read more about different telescope designs in our buying guide From there it is a breeze to select what you want to see using the computerized hand control, which features automatic slewing to over 4,000 celestial objects, as well as manual high-speed slewing and fine-centering at the touch of a button. Even a beginner can master this telescope within just a few observing sessions. Also provided: a Star Pointer finderscope designed to help you point the telescope while scanning the sky with both eyes, the Sky Level I CD-ROM with a database of 10,000 celestial objects, and a sturdy, adjustable aluminum tripod with an accessory tray. Featuring a 114mm (4. 5-inch) diameter Newtonian reflector with a focal length of 1,000mm (focal ratio of f/9), this telescope affords approximately 265 times the light-gathering power of the naked eye. And, with the two eyepieces (25mm and 10mm) included here, it offers maximum magnifications of 40x and 100x, making it capable of revealing fine detail within galaxies and nebulae. The NexStar 114 Newtonian reflector has 265 times the light gathering power of the average human eye, revealing fine detail within galaxies and nebulae. This compact design brings objects into view with a 114mm aperture, 1000mm focal length capable of achieving magnifications of 40x and 100x with the included eyepieces. Its large 4. 5" diameter outshines smaller scopes. Polar caps on Mars become visible along with the cloud belts on Jupiter. The rings of Saturn are also clearly visible. Perhaps most exciting is the sheer variety of deep sky objects (stars, clusters, nebulae). Because of their optical design, reflectors are best suited for astronomical use.

Here are a couple hints for you once you get your hands on your new NexStar 114. Often, it is tempting to look at the Moon when it is full. At this time, the face we see is fully illuminated and its light can be overpowering. In addition, little or no contrast can be seen during this phase. One of the best times to observe the Moon is during its partial phases (around the time of first or third quarter). Long shadows reveal a great amount of detail on the lunar surface. At low power you will be able to see most of the lunar disk at one time. The optional Reducer/Corrector lens allows for breath-taking views of the entire lunar disk when used with a low power eyepiece. Change to higher power (magnification) to focus in on a smaller area. Choose the lunar tracking rate from the NexStar's MENU tracking rate options to keep the moon centered in the eyepiece even at high magnifications. Observing the Planets Other fascinating targets include the five naked-eye planets. You can see Venus go through its lunar-like phases. Mars can reveal a host of surface detail and one, if not both, of its polar caps. You will be able to see the cloud belts of Jupiter and the great Red Spot (if it is visible at the time you are observing). In addition, you will also be able to see the moons of Jupiter as they orbit the giant planet. Saturn, with its beautiful rings, is easily visible at moderate power. Remember that atmospheric conditions are usually the limiting factor on how much planetary detail will be visible. So avoid observing the planets when they are low on the horizon or when they are directly over a source of radiating heat, such as a rooftop or chimney.

The complete package has everything you need to get started except the batteries. The box contains high and low power eyepieces (9mm and 25mm), the computer controller, an adjustable tripod, a red dot finder, and even a planetarium program for your personal computer. The NexStar 114 SLT's compact Newtonian optics produce images that are three times brighter than 60mm beginner scopes. With this telescope it's easy to see Saturn's rings and Jupiter's cloud belts. When the night air is still and clear I've been able to see the Cassini division in Saturn's rings and even spot the shadow of Jupiter's moons crossing the planets cloud tops! Deep space objects like star clusters and galaxies also show up nicely. The Ring Nebula M57, for instance, shows up as a pale smoke ring, and globular cluster M13 begins to reveal its individual stars. Celestron's computerized SkyAlign system is remarkably quick and easy to use. If you can see the moon, you can align this telescope! When you turn on the telescope, select "Solar System Align" on the hand control, enter the date and time, point the telescope at the moon, and press the "Align" button. That's all it takes; the computerized tracking system takes over and begins tracking, quietly, and accurately. Experienced users will love the "Auto Two-Star Align" and "SkyAlign" modes because they allow the telescope to point accurately at over 4,000 objects in the NexStar database. The accurate tracking allowed me to use a Celestron NexImage to take some nice close-up pictures of the moon and planets. The biggest drawback to a computerized telescope is its battery consumption. The standard AA batteries only last a few hours, but the NexStar 114 SLT works very well with an external 12-volt battery such as Celestron's Power Tank. The other drawback comes from the NexStar 114 SLT's compact optical design. This telescope uses a short-focal-length mirror combined with a corrector lens to simulate a traditional long tube reflector. This works pretty well at moderate magnification levels, but the mirrors may need to be fine-tuned, or "collimated," to get the best high power images. I find Celestron's Collimation Eyepiece helps me get this fine tuning just right, but the reward is sharp images, even when I use the high power 9mm eyepiece with a barlow lens for a magnification over 200x. -Jeff Phillips Pros: Easy computerized GoTo system Good (but not great) optics Includes everything but the batteries Cons: Short battery life Optics may need occasional fine tuning.

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 Venus Pros: Small, portable and affordable Very good optics Easy computerized tracking Cons: Rechargeable batteries not included Small size limits deep space viewing.

Each AstroMaster model is capable of giving correct views of land and sky. The AstroMaster Series produce bright, clear images of the Moon and planets. It is easy to see the moons of Jupiter and the rings of Saturn with every one of these fine instruments. For views of the brighter deep space objects like galaxies and nebulae, we recommend the larger aperture and light gathering ability of the Newtonian reflectors. If your interest is strictly watching whales, spotting birds, viewing nature, orchecking out your favorite star or planet the altazimuth-mount.

5mm eyepiece (120x) I can easily detect the shadow cast by the planet on the rings, and even glimpse the ring's Cassini Division. When the mirrors are properly lined up or "collimated," the images are reasonably sharp up to magnifications of 225x. I find a collimation tool helps get this fine tuning just right. As good as the optics are, however, the effect of cost-cutting shows up in the mechanical components. The focuser is plastic, the finder scope is plastic, the rings that attach the telescope to the tripod are plastic. Even when the tripod legs are clamped at their shortest setting, the telescope wobbles when I try to focus at higher magnifications. Celestron's instruction manual correctly recommends that most viewing be done in the range of 40x to 130x. So what about that 675x magnification proclaimed on the box? I'd say it's not worth the trouble. Overall, the Celestron Powerseeker 114 is a budget priced telescope with good optical performance, especially when using the low power K20 eyepiece. If you're willing to spend a little more money, either Orion's SkyQuest XT4. 5 or Celestron's Firstscope 114EQ will give you a sturdier mount, an improved finder scope, and better eyepieces. Also, for about the price of the Powerseeker 114, I like the dependable refractor design of Celestron's Firstscope 70EQ. -Jeff Phillips Pros: Low cost Good optics Serviceable K20 eyepiece Cons: Wobbly mount Difficult to collimate Plastic finder and focuser.

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 Pros: Excellent optics Light and portable Computerized GoTo tracking Cons: Short battery life Too light for deep space photography Suggested Options: Celestron Nine-Piece Accessory Kit Celestron Power Tank Battery Celestron NexImage Webcam.

5 is considered a very small scope. Tiny, in fact (It’s so small, astronomers are buying them just because they think they're so cute). Make no mistake, though-the XT4. 5 is a full-fledged telescope, and is a serious observing tool that could last you for years. Your money buys you a lot in this case. Included are a good-quality 4. 5" f/8 primary mirror, two eyepieces, a finder, and a CD-ROM with a stripped-down version of The Sky, a software guide to the sky. The scope comes in two cartons. One contains the optical tube, and the other is a flat-packed box containing the base, which you assemble yourself. Orion includes all the hardware and tools you need, and the instructions are well written. Allocate about 30 minutes to assemble and align everything. See a detailed view of the XT4. 5's features There are a couple of cost-cutting measures. The primary mirror is spherical, not parabolic (this is not likely to affect the views, however). Also, the focuser is plastic. While I’ve never seen one break, plastic focusers are by nature less robust than metal ones. Finally (and this may be the most serious concern of all), the scope is a little short for an adult. The eyepiece is only 3 feet off the ground, which may force you to stoop over (hint: try sitting on a short chair or stool while observing). On the other hand, the height is ideal for a child, and as a result, I heartily recommend this telescope for children. Under the stars, the XT4. 5 exhibits excellent performance. Once properly collimated (aligned), the optics give clear, sharp, contrasty views. I’ve spent enjoyable nights using these telescopes, both as a teaching tool and by myself. Jupiter’s cloud band and four moons are no problem to see, nor are Saturn’s rings. The Orion Nebula is a glowing fan of green gas, with a quartet of tiny stars at its core. Under dark skies (and with some diligence) the XT4. 5 can even pull in some of the fainter deep sky objects, like the brighter galaxies in the Virgo Cluster. Despite the fact that I have a garage full of expensive telescopes, I never feel compromised with any of Orion’s XT scopes. As recently as a few years ago, the old adage regarding telescopes was that you must spend at least $300 to avoid buying junk. While this is still mostly true, Orion’s little XT4. 5 breaks the price barrier in a big way. As long as you can deal with the short eyepiece height, it’s a great starter scope. Pros: Very good optical and mechanical performance Fully accessorized Great value Cons Short eyepiece height Plastic focuser.
