Celestron NexStar 4 SE Telescope


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.

Moon

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.

Jupiter

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

Pros:

• Small, portable and affordable
• Very good optics
• Easy computerized tracking

Cons:

• Rechargeable batteries not included
• Small size limits deep space viewing

Celestron NexStar 8 SE Telescope


Amazon.com Review Celestron's Nexstar 8 SE telescope combines excellent optics and computerized "GoTo" tracking in a package that's light, portable and affordable. The legendary performance of Celestron's orange tube C8 telescope has been updated with high performance Starbright XLT coatings, and the single arm Nexstar mount now includes Celestron's easy to use "SkyAlign" technology.

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.

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

Choosing and Using a New CAT: Getting the Most from Your Schmidt Cassegrain or Any Catadioptric Telescope (Patrick Moore's Practical Astronomy Series)


Choosing and Using the New CAT will supersede the author’s successful Choosing and Using a Schmidt-Cassegrain Telescope, which has enjoyed enthusiastic support from the amateur astronomy community for the past seven years. Since the first book was published, a lot has changed in the technology of amateur astronomy. The sophistication and variety of the telescopes available to amateurs has increased dramatically. Computerized SCTs, Maksutov-Cassegrains, and most recently Meade’s new and acclaimed Ritchey-Chrétiens have come to dominate the market. That means that all amateurs considering the purchase of a new telescope (not only a SCT, and not just beginners) will benefit from this detailed guide. Choosing the right telescope for particular kinds of observation (or even for general work) is far from easy – but Rod Mollise gives invaluable advice and guidance.

Choosing and Using a Schmidt-Cassegrain Telescope : A Guide to Commercial SCTs and Maksutovs (Practical Astronomy.)


Amateur astronomy is becoming more and more popular, mostly because of the availability of relatively low-cost astronomical telescopes of superb quality - commercially-made Schmidt-Cassegrain and Maksutovs. Rod Mollise's book contains everything amateur astronomers need to know about these telescopes.

Using the Meade ETX: 100 Objects You Can Really See with the Mighty ETX (Patrick Moore's Practical Astronomy Series)


The Meade ETX range of telescopes is one of the most successful ever made. It is low-cost, has sold in its tens of thousands, and is available in almost every country. Here, ETX expert Mike Weasner reveals everything any amateur astronomer ever wanted to know about the telescope. First book dedicated entirely to the ETX. Written by an acknowledged world authority. Describes the "best" 100 objects to begin observing. Contains detailed hints and tips aimed at getting the best out of the ETX. Features imaging (photographic and digital) as well as visual observing.
