## 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).

## 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
