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 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
- Wide field views
- Computerized go-to tracking
- Light and portable
- Short battery life
- Sensitive to vibration
Top Customer Reviews
When the scope is working, it's fantastic (see below if you have a non-working scope with a boot loader failure). The Newtonian design is comfortable to look through - the eyepiece is at the front of the scope, and it is positioned around eye-level when standing. Newtonian optics are also simple, which keeps the cost down (and minimizes light lost to lens absorption).
The optic properties of this scope are outstanding. The 650mm focal length and 150mm (about 5-1/8") aperture are great specs, especially when paired with the highly-recommended Celestron accessory kit (Celestron Model 94303, available on Amazon). The scope comes with a 9mm and 25mm eyepiece, for magnifications of 72 and 26 power (magnification is focal length divided by eyepiece length, so magnification increases as focal length increases, and decreases as eyepiece length increases). The big 130mm aperture of this scope gives the scope a maximum useful magnification of about 307 power, using the rule of thumb that you can magnify 60 times for each inch of aperture.
At a focal ratio of f5, this is a fairly "fast" scope, meaning it lets in a lot of light for it's focal length. The f-number is the focal length divided by the aperture size, and the lower the f-number, the faster the scope. Faster is (generally) better. F-numbers will be familiar to photographers, and telescopic "lenses" operate on the exact same concept as fast photographic lenses. In photography, a lens is "fast" because it allows a shorter shutter speed (because it lets in more light), meaning you can capture faster motion that would be blurry with a longer exposure (as would be required by a "slower" lens).Read more ›
The optics of this scope are pretty good. And the idea of an alt-az tracking mount with go-to features is sound. But the kit as actually delivered is problematic. If my experience is any indication, about half of the time, the kit will be out of commission due to failure of critical components.
As I noted in my original review, the Finderscope failed shortly after I got the kit, making the scope extremely difficult to aim and steer, and impossible to align for purposes of the tracking feature.
Since then, the Altitude motor has failed twice, and the plastic bracing of the tripod split clear through--fortunately NOT while it was holding the scope tube. Each of these situations has meant 2-1/2 months of the kit being out of commission while I begged Celestron for a return materials authorization number, shipped the materials to Celestron, waited for Celestron to check the parts in, and then waited 6 weeks for them to service or repair the parts.
The root cause is apparently low-quality materials, including cheap Chinese motors.
Celestron sells the SLT mount, hand-controller, and tripod as a kit without any optics for about $350. I recommend steering clear of that kit and any kit containing a tripod or mount made by Celestron, including their much-ballyhooed self-aligning SkyProdigy mounts, which, in their photos, appear to be made from the same underlying components.
At this point I am more seriously looking at products from Orion and Meade to replace the unreliable components from Celestron.Read more ›
