Celestron NexStar 130SLT Newtonian Reflector Telescope
Celestron's NexStar SLT 130 is definately a wise choice for a first GoTo telescope.
A beginner's GoTo telescope shouldn't be difficult to assemble, set up and align, and Celestron has made sure this doesn't happen. Setting up the NexStar SLT 130 Newtonian Reflector is nothing but a piece of cake! All the user must do is take the 5" Optical Tube and mount it on the altazimuth mount and power on! The telescope is powered with 8 AA batteries.If the user wishes to avoid running the telescope by batteries (eg. outlet near by, conserve power etc.), no problem, the 17 hour and 7 hour Powertanks from Celestron are great optional accessories to by along with this telescope as well and serving a number of other unrelated purposes. After setting up and powering on, simply align the telescope with SkyAlign, Two Star Alignment, or One Star Alignment.
How to align the telescope:
There are a number of different methods the user can use to align their scope.
SkyAlign requires the observor to slew to three stars without even knowing the names! All the user must know is the date, time, and location and input it in the hand controller. The software can calculate and map out the sky and determine what stars the user chose. If it sucessfully calculates, it will display "Matched Confirmed" and the user is ready to observe. However, it is recommended that the user press undo after this message is displayed to ensure the stars it guessed were correct. To esnure alignment goes as smoothly as possible, follow these suggestions:
- Level Tripod before alignment
- Use stars far away from each other in degrees and avoid choosing a third star directly inbetween the previous two.
- If you need to choose a planet or the moon, go ahead! SkyAlign can also recognize terrestrial objects.
- Avoid choosing a star directly next to a brighter one or the moon.
- Slew to align the same direction the mount performs a GoTo.
TwoStar Alignment does require the user to have some basic knowledge of the night sky. They must enter the date, time and location, but also must slew to two bright stars and identify them in the hand controller manually. Important tip! - Center the stars as much as possible by decreasing slew rate.
Auto TwoStar Alignment is basically the same as TwoStar, but the user must only no one star to slew to and identify. By calculating location, time, date, and the location of this star, the NexStar GoTo telescope automatically with slew to a second one to align.
One-Star Alignment is the same as TwoStar, but only requires slewing to and identifying one star. This method is primarily recommended to look at terrestrial objects such as planets and the moon. Don't use this to view deep sky objects.
Solar System Alignment requires inputting the location, date and time and slewing to a planet, the moon, or even the sun during daylight. WARNING: NEVER EVER SLEW TO THE SUN WITHOUT A PROPER SOLAR FILTER. FAILURE TO DO SO WILL RESULT IN POSSIBLE PERMANENT DAMAGE TO THE TELESCOPE AND ACCESSORIES AND WORSE, THE OBSERVOR'S EYES.
Re-Alignment feature is a special alignment method Celestron implemented into the NexStar 130 SLT Newtonian Reflector. If the observor needs or wants to choose a new star to align to for better accuracy without having to re-align, they can by choosing and identifying a third star.
Time to Observe!
Once the user has finally aligned their telescope properly, the wonders of the night sky are at their hands! With a 5" aperture, it has a reasonable light gathering power for a beginner's scope and with a fast focal ratio of f/5 (aperture/focal length; 130mm/650mm=0.2mm), it is quite satisfying for both planets and those brighter deep sky objects such as open cluster, emission nebulae, planetary nebulae, and even some of the brighter galaxies.
- Orion Nebula (M42)
- Andromeda Galaxy (M31)
- Perseus Double (NGC884, NGC869)
- Hercules Globular (M16)
- Lagoon and Trifid Nebulae (M8, M20)
- Eagle and Swan/Omega Nebulae (M16, M17)
- Ring Nebula (M57)
- Whirlpool Galaxy (M51)
The Newtonian Reflector optical tube style doesn't suffer from chromatic aberration, a common issue with refractors and overall provides a well designed system at reasonable prices, and this is no different with the NexStar SLT 130.
new! Read an in-depth review of the Celestron NexStar 130 SLT by Ian Morison, Jodrell Bank Observatory
The popularity of our NexStar 114 models inspired us to go bigger! We are proud to introduce NexStar 130 SLT. The NexStar 130 SLT has 30% more light-gathering power than our 114mm telescope.
And the 130 SLT, like the other models in the SLT Series, comes with a fully computerized hand control. The computerized hand control gives you the ability to automatically slew to any of its 4,000+ objects, including over 600 galaxies, 300 clusters and dozens of beautiful binary stars. With its pre-assembled, adjustable steel tripod, the NexStar 114 SLT can be up and ready to use in a matter of minutes. Our new SkyAlign alignment technology and the included StarPointer Finderscope with a red LED makes aligning a breeze.
View the details of the lunar surface, the rings of Saturn, the polar ice caps on Mars, the cloud belts on Jupiter or a number of the Messier objects such as the globular cluster in Hercules (M13), or the Great Nebula in Orion (M42). Begin to explore some of the fainter Messier objects using the additional light-gathering capabilities of the 130 SLT's 5" primary mirror.
Because of the Newtonian design, the mirror gives fully color-corrected views that are best suited for astronomical use.
Designed to be an affordable entry level to mid-level computerized GoTo telescope, the NexStar Star Locating Telescope (SLT) refractors, reflectors and Maks are available in the most popular sizes and are loaded with valuable design features. With pre-assembled, adjustable stainless steel tripods and quick release fork arms and tubes, NexStar SLT telescopes can be set up in a matter of minutes — with no tools required! You can see details of the lunar surface, Venus and its phases, Mars resolved as an orange disc, Jupiter and its four moons, Saturn with its rings plainly visible and much more! Most NexStar SLTs can also be used as a land-based spotting telescope.
