Digital Cameras Photo Reviews of Celestron NexStar 130 SLT Computerized TelescopeCustomer Review: Great scope in general with a few caveats. Summary: 4 Stars
I have revisited my review and dropped 1 star after owning this scope for 2 years now. The 1 star drop to 4 stars is due to the azimuth [horizontal] motor acting erratically now. It will slow down as if it is binding somewhere, then speed way up for periods. Contacting service had me running various basic tests, but all failed, so they gave me an RMA number to send back for repairs. I have decided to wait for winter to return the mount so I won't "miss" it for the 3-4 months of coldest weather, but now being out of warranty, I've no idea how much this repair will cost. I will update this review again after the repair. In any case, since I don't use it all that much, I'd have expected this scope to last a lot longer before this sort of thing happened.
(Original Review starts here)
I have now owned this telescope for 4 months, using it (so far) exclusively on upper Manhattan... yes, NYC! So my experience so far is with the moon and planets. For this, it's a great telescope, bringing out many details quite nicely. Set up was quick and easy to understand. Once set up, I did notice a little tweaking on the alignment [mirror collumation] was needed, and after some indoor alignment, followed by "bright-star" fine tuning, this telescope's fine optics came into full display.
The 2 eyepieces that come with the scope are quite good, but it was with my 7mm Nagler eyepiece that Saturn's rings shone fine, and Jupiter's cloud bands popped right out!
Now, the few caviats: This scope is not good on a windy day as it is prone to vibrations! Vibrations induced from touching the scope to focus quickly disappear so, for normal use, it's quite tolerable. As to the "goto" system: If you're going out just to spot the moon or planets, use the "solar system" alignment. It's quick and only takes one planet or the moon to align. 3-star alignment for multiple object gazing is a bit trickier, but here's the two secrets: The tripod comes with a built-in bubble level. USE IT! If your scope is not level, alignment will fail. Also, make sure your watch is accurate! If you enter the time and it's more than 30-45 seconds off, again, alignment will fail!
Take the time to set up the telescope carefully first [yes, there's a bit of a learning curve, but once you've memorized it, it goes quickly. Yes, you'll have to "fiddle" with their battery compartment cover, but it will pop into place when you've got the 2 battery holders in the right position. Finally, get yourself a really GOOD eyepiece somewhere in the range of 5-8mm for truly spectacular lunar and planetary views. Be prepared to spend $150-$300 for that eyepiece, but then you'll experience this scope's full optical potential!
Description of Celestron NexStar 130 SLT Computerized TelescopeThe CelestronŽ NexStarŽ SLT Series 130 SLT reflector telescope showcases a computerized hand control and a 4000+ object database. With a touch of a button you can select the object catalog, change the slew speed, view fascinating information about an oject, or simply know if a desired object is visible in the sky. It comes equipped with a sturdy steel tripod, a StarPointerŽ finderscope, software, and more. Amazon.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.  | | 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
