Review Meade ETX125AT Telescope w/ UHTC, Autostar Controller (497) and Tripod (884) / Meade 0515-03-21:

Meade ETX 125AT Astro Telescope. The ETX-125EC permits a broad range of astronomical study. In deep space, the ETX-125EC's larger aperture enables the observation of galaxies and nebulae in much wider extension and permits the resolution of celestial objects as faint as magnitude 12. 5. The entire Messier listing of 110 objects is now not only visible, but, in addition, every object takes on a readily discernible structure. The Autostar controller turns the ETX-125EC into an automatic celestial object-locating system. The UHTC Difference Each time light encounters a mirror (above) or lens (below), some light is lost. In the case of a lens, light is lost at both the entrance to and exit from the lens. UHTC dramatically decreases this light loss. Image brightness in a telescope is crucially dependent on the reflectivity of the telescope's mirrors and on the transmission of its lenses. [+]
Neither of these processes, mirror-reflectivity or lens-transmission, is, however, perfect; light loss occurs in each instance where light is reflected or transmitted. Uncoated glass, for example, reflects about 4% of the light impacting it; in the case of an uncoated lens 4% of the light is lost at entrance to and at exit from the lens, for a total light loss of about 8%. Meade standard mirror and lens coatings equal or exceed the reflectivity and transmission, respectively, of virtually any optical coatings currently offered in the commercial telescope industry. Ultra-High Transmission coatings (UHTC), recently developed at the Meade Irvine coatings facility, however, have permitted the vacuum-deposition of a series of exotic optical coatings precisely tuned to optimize the visual, photographic, and CCD imaging performance of Meade telescopes. This telescope includes primary and secondary mirrors coated with aluminum enhanced with a complex stack of multi-layer coatings of titanium dioxide and silicon dioxide. The thickness of each coating layer is precisely controlled to within 1% of optimal thickness. The result is a dramatic increase in mirror reflectivity across the entire visible spectrum; at the important hydrogen-alpha wavelength of 656nm. - the predominant wavelength of emission nebulae - reflectivity is increased from 89% to over 97%. This telescope presents dramatically brighter images on the full range of celestial objects — from emission and planetary nebulae such as M8, M20, and M57 to star clusters and galaxies such as M3, M13, and M101. Observations of the Moon and planets, since they are observed in reflected (white) sunlight, benefit in image brightness from the full spectrum of increased transmission. And more The computer-driven Autostar controller makes it easy to find 30,000 celestial objects. Just plug the Autostar into the telescope's HBX port in place of the standard-equipment electronic controller, do a quick telescope alignment, and you're ready to observe any object in the Autostar's 30,000-object database. ETX optical systems include a Maksutov meniscus corrector lens of Grade-A BK7 optical glass. High-transmission magnesium fluoride (MgF2) coatings on both sides of the correcting lens, as well as aluminum-silicon monoxide coatings on the primary and secondary mirrors, are provided as standard equipment. Use the standard pushbutton electronic controller at any of four dual-axis speeds: 8x sidereal for image centering in the main telescope at high power; 32x for image centering at lower powers or for pushbutton object tracking in the altazimuth mode; slow mode for image centering in the viewfinder or for terrestrial tracking of nature and sightseeing; or medium speed for fast slewing across the sky. The observer can instantly select any of these speeds simply by depressing the speed button on the controller. The telescope’s ultraportable design allows the viewer to view from any flat surface, be it a window sill, car hood, or picnic table. The optional tripod can raise the telescope to any comfortable height. The Nuts and Bolts 1. Eyepiece 2. Viewfinder 3.

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

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 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.

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. 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. The moon seen through the Celestron NexStar 8SE telescope. (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.

Celestron's NexStar software technology will model the night sky to determine the position of every star, planet and celestial object above the horizon. The CPC database contains over 40,000 celestial objects including Messier objects, the Caldwell Catalog, as well as NGC Galaxies, nebulae and planets. An ergonomic design comfortably lifts and moves the telescope from location to location Star diagonal provides more comfortable viewing position when observing objects that are high in the sky Convenient remote hand control holder allows you to view information hands-free while using the scope SkyAlign allows you to align on any three bright celestial objects, making for a fast and easy alignment process Flash upgradeable hand control software and motor control units for downloading product updates over the Internet Auxiliary port for additional accessories such as Autoguider, GPS accessory Aperture - 203. 2mm (8) Focal Length - 2032mm (80) Focal Ratio - 10 50 Finderscope with quick release bracket Magnification - 29x and 480x Computer Hand Control - Flash upgradeable, double line, 16 character Liquid Crystal Display, and 19 fiber optic backlit LED buttons Tracking Rates - Sidereal, Solar and Lunar Tracking Modes - Altazimuth, EQ North & EQ South Alignment Procedures - SkyAlign, Auto Two-Star Alignment, Two-star Align, SolarSystem Align, Celestron's CPC 800 XLT telescope combines excellent Schmidt-Cassegrain optics with a state of the art computerized mount featuring GPS technology and user friendly design. This telescope is a solid all-around performer likely to please both the experienced observer and the new astronomer. After using older computerized telescopes, Celestron's new SkyAlign system seems almost like magic. [+]
I don't need to remember obscure star names or use a star chart, I just point the telescope at three bright stars or planets and the CPC 800 tells me the star names! SkyAlign is one of several alignment options, and some options can even be used during daylight. The drive base and heavy duty CPC tripod are unusually solid, it's the same base and drive system used on the larger CPC 1100 telescope. When I rap on the telescope fork the vibration is gone in less than a second. In practice this means easier focusing even at high magnification. The solid base and precise tracking is a real advantage while viewing the planets and while photographing them. I've been able to image the planets at focal lengths of f30 and f40 which would be quite difficult without perfect tracking. Saturn as seen through the Celestron CPC 800 XLT computerized telescope. The excellent optics of the CPC 800 XLT telescope show me excellent views of the planets. When I look at Jupiter with a 12. 5mm plossl eyepiece (about 160x magnification) I see multiple cloud bands and I can see the pale color of Jupiter's famous Great Red Spot. One night when the air was unusually still and clear I used a 7. 5mm Ultrascopic eyepiece with a 2x Barlow for a magnification of 533x. Jupiter's moons were plainly resolved as tiny disks that night. When I look at Saturn at 200x I can usually see the Cassini division in the rings and make out four or five moons. When Mars comes closest to Earth every two years I've even been able to spot dust storms blowing across the Martian desert. The CPC 800 XLT also delivers beautiful views of deep space objects. The CPC 800 is large enough that galaxies begin to reveal their structure and globular star clusters are well resolved. At a recent astronomy viewing night at a local school, some of the students liked globular cluster M13 the best. They said it looked like a snowflake made of tiny stars! The well known Orion Nebula is a winter highlight. Most telescopes will show four stars in the Trapezium, the bright multiple star inside the Orion Nebula, but with the CPC 800 I can often pick out faint stars "E" and "F" as well. The accessories with this CPC 800 XLT package include an 8x50 finder scope, a 40mm plossl eyepiece (50x magnification), the NexStar computer hand control, and a 12-volt car battery adapter. The description says "Telescope Only" because the tripod and power supply are not included. Celestron's new Heavy Duty Tripod is designed to attach easily to the CPC 800 drive base; it's an option you'll want. You'll also need a 12-volt power supply. An AC adapter is available, but I like using a 12-volt battery pack because I don't need to be near an extension cord to use the telescope. A few good eyepieces help me take full advantage of the CPC 800's excellent optics. Plossl eyepieces like the ones in Celestron's Nine-Piece Accessory Kit would be an economical way to get started, and of course premium eyepieces like the TeleVue 10mm Radian offer delightful views of the planets. If I were choosing just two eyepieces to add to the CPC 800, I'd pick a 10mm X-Cel eyepiece (200x for planet viewing) and a 21mm X-Cel eyepiece (100x for globular clusters and galaxies) to go with the standard equipment 40mm (50x) eyepiece. The CPC 800 XLT is an excellent all-around telescope. The C8 optics are large enough to give me delightful views of deep space objects, and the optics are powerful enough to show me amazing views of the planets. Even with all this power the whole system is portable enough that I can easily transport my telescope to the local high school and share the view on Astronomy Night. -Jeff Phillips Pros: Excellent optics Solid drive base Easy computerized finding and tracking Cons: 12-volt adapter not included Tripod not included Suggested accessories: Celestron Nine-Piece Accessory Kit Celestron Power Tank battery Celestron NexImage web-cam Celestron Adjustable Heavy Duty Tripod.
