## Description

The Celestron NexStar 90SLT is a computerized telescope that offers a database of more than 40,000 stars, galaxies, nebulae, and more. The telescope locates your object with pinpoint accuracy and tracks it. At the heart of the telescope's Maksutov-Cassegrain optical design, a 90mm primary mirror gives fully color-corrected views ideal for astronomical use. The 90SLT comes with a fully computerized NexStarPlus hand control. The computerized hand control gives you the ability to automatically slew to any of its 40,000+ objects, including over 600 galaxies, 300 clusters, and dozens of beautiful binary stars. This telescope for adults and kids is ideal for weekend camping trips or excursions to dark sky sites. Its compact form factor makes it easy to transport and assemble just about anywhere. With its pre-assembled, adjustable steel tripod, the NexStar 90SLT can be up and ready to use in a matter of minutes. Our SkyAlign alignment technology and the included StarPointer Finderscope with a red LED make aligning a breeze. Simply center any three bright objects in the eyepiece and the NexStar SLT aligns to the night sky, ready to locate thousands of objects. The NexStar 90SLT Computerized GoTo Telescope also includes a free download of our Starry Night Special Edition astronomy software for an interactive sky simulation. This computerized telescope allows you to view the lunar surface, the rings around Saturn, the moons of Jupiter, and a number of the Messier objects, such as the globular cluster in Hercules (M13) or the Great Nebula in Orion (M42).

Review: This is an awesome beginner Telescope! - I have use this to view the Sun (with a Bader solar filter), Moon, Jupiter, Saturn, Albireo, Andromeda, and Pleiades. You get stunning views of the moon and sunspots are very distinguishable with this scope. Saturn is pretty small, but the rings are distinct and some moons can be spotted around Saturn. I was able to faintly see the bands of Jupiter and the Galilean moons are pretty bright. You would need a bigger telescope to get more detail from the planetary objects, but the views you get in this scope still makes anyone who looks pretty amazed at what they are viewing. I love the fact this has a computerized tripod mount. This takes the frustrations away of trying to keep an object in view as well as trying to locate something in the vast night sky. The setup take some practice, but it does get easier after a few attempts. My neighbor has an 8” Nexstar SL with the StarSense Automatic Alignment Accessory and I still usually beat him to having an aligned telescope by doing it with the built in SkyAlign method. The tracking is good as long as you have fresh batteries, but I highly recommend using an external power source because the batteries get drained in a few hours. I also recommend using an app to help locate objects. I am planning on getting the WiFi modules so I can use my phone to control the telescope. The included hand controller does take some time to learn, and the menu navigation can be clunky. You can use the free Celestron SkyPortal app for control your scope if you have the WiFi module. Once you have the telescope aligned it is pretty accurate on its tracking. One night I centered Saturn and went inside to watch TV for 2 hours and I was amazed that Saturn was still in the eyepiece when I came back out! You will want to make sure you have the tripod level, fresh batteries, the correct latitude/longitude, time, and date to help ensure your tracking is accurate. This Telescope has made me excited to get out on clear nights and discover the night sky and has also helped get me into trying astrophotography. I was able to use my Olympus E-PL5 the other night piggy backed on the telescope which helped me get a decent shot of Andromeda. I took an hour of exposures it was nice to have the tracking of the telescope available so Andromeda stayed centered in my camera. I also bought a T-Adapter so I could photograph objects using the telescope as a prime lens. My sun and moon shots came out very clear using this method. The sun and moon shots attached are not cropped, and you can see almost the entire frame is consumed by the sun or moon which give a great amount of detail. I highly recommend this telescope! If you can afford a larger telescope, then get the biggest one you can afford, but even though this is only a 3 1/2" scope it can give you some great views of the night sky.
Review: I saw Saturn so clearly! - My husband who has had scoping experience very easily set this telescope up and I was able to view Saturn for the first time...wow, I am going to have fun with this. I bought the filter accessories along with it. After seeing that it takes eight double A batteries, I decided to buy the power pack because then I don't have to worry about the motor running out of juice. A solar filter for a Four inch fit was ordered afterwards too. I looked at the full moon tonight with the orange-colored filter and saw all the craters and mountains super clearly. It is also small enough to sit on my unused treadmill when not in use, ready to grab and go. The only problem was that my husband decided to take the cradle for the hand control off to move to another leg of the tripod and the plastic broke. It is now taped to the leg and I will try and replace it. Best buy for such a nice telescope....and I am a true beginner knowing nothing about them. My more experienced husband says it is a fantastic scope for this price. Click and buy one to see Comet ISON this September! P.S. I emailed Celestron about the cradle and they sent a new one immediately! Awesome customer service...this company is on my "good guys" list. I will buy from them again and again.

## Questions & Answers

**Q: Has anyone compared nexstar 127 slt to nexstar 130 slt?**
A: The 127 slt will balance better on the mount because of its compactness. Also the 127 does not have to be collimated

**Q: Did you see Jupiter.**
A: Greetings,

Amazon has, unfortunately, mixed all SLT scope reviews and Q&As together. But the 127 Mak is an excellent planetary, lunar and binary star telescope due to its nearly perfect optical design and long focal length. Far superior to a fast Newtonian with its anemic magnifications and coma.  The basic detail on Jupiter with the 127 Mak is easy: at least 4 bands, the red spot (though it is shrinking of late and losing its color). The four major moons are easy targets as they cross Jupiter's disk. Their shadows are black dots. Performance is limited to steady 'seeing' conditions.

Steve Franks

**Q: Aside from the 1 inch aperture difference, what are the differences between the nexstar 127slt and the similarly priced nexstar 4se?**
A: One big difference is that the 4SE has Starbright XLT coatings which is the best coating you can get. It makes a big difference, and in all likelihood that offsets the 1 inch larger meniscus on the 127 SLT

**Q: What additional filters and lenses (brands/types) would you recommend getting for those of you who got others? I'd like a nice moon filter for sure.**
A: Greetings,Don't buy ANY accessory until you KNOW you NEED it. Color filters are an excellent example. Only after you become accomplished as an observer should you consider filters. Carefully research the type and focal length eyepiece you need to build a good set. Three are all one really needs - low, medium and high. A Barlow may be a good idea to double your eyepiece collection but get the proper Barlow. Don't duplicate what eyepieces you already have. Stick with a 2x or 2.5x Barlow. But get your eyepieces first! That will determine the Barlow requirement. I prefer full eyepiece sets, others prefer to use Barlows.The 127 Mak, with its long f/ratio and excellent optics is very forgiving with eyepieces. Inexpensive eyepieces will be superior performers with it though they would fall flat with fast ratio Newtonians, for instance. And keep the number of elements in the eyepiece to a minimum. Many elements rob you of light which is a precious thing with just 5" aperture. I can highly recommend the Agena Dual ED Starguiders. They are top notch performers with generous fields of view; flat fields; excellent color correction; suitable for deep sky, planetary, or binary star work; with a great build quality at a reasonable price.http://www.amazon.com/Agena-1-25-Starguider-Dual-Eyepiece/dp/B00YFZQ33OSteve Franks

### ⭐⭐⭐ Good Telescope for the money
*by R***R on November 3, 2013*

For the money, this is the perfect choice for a beginner. I wanted something simple to start astrophotography. The assembly was extremely easy. Aligning the telescope with the NexStar is a bit more difficult. The first night we tried, it was a beautiful, star-filled night--no moon. We couldn't see Venus through the telescope, and we thought perhaps the telescope itself was broken. The next day, we used the telescope in daylight and could see trees, etc, so we decided that the stars were just not bright enough the previous night for us to align the NexStar. We are going to try and align on the next full moon. I will post a follow-up to let you know if it works. The telescope itself is heavy-duty. The stand is rugged. The whole thing weighs about 30 pounds. All in all, I think this will be a great telescope, and I'm looking forward to getting the other things in so I can take some pictures. Update: I'm downgrading my rating a bit, as I've found that after several attempts to align the NexStar, it is very difficult for a beginner. I am new to astronomy and the NexStar sold me on this telescope; I love the telescope, but I'd have better luck finding the planets, etc. on my own than with this mount. It also seems to shake a bit, even on firm ground. I'm ordering the pads for the legs of the tripod to see if I can keep the vibrations to a minimum. We saw Venus this evening, and I did take some beautiful pictures of the moon this evening with the adapter for my Canon Rebel. It isn't a bad scope, but I really don't like the Nexstar thing at all. I'm hoping by the time ISON gets here I'll have a better handle on how to work it. BE SURE TO GET THE MOON FILTERS! Even with the filter, the moon was super bright!
