About Celestron NexStar 102 SLT

The popularity of Celestron's previous short tube refractor models inspired us to go a step further with the introduction of Celestron's NexStar 102 SLT. You'll find that astronomical viewing is a delight with this large, powerful 4" telescope. The 102 SLT offers a 63% increase in image brightness over 80mm models. This short-tube telescope with a fast f/6 optical system gives images that are bright and crisp. And the 102 SLT, like the other models in the SLT Series, comes with a fully computerized hand control with a database of over 4,000 celestial objects! With its pre-assembled, adjustable steel tripod, the NexStar 102 SLT can be up and ready to use in a matter of minutes. The SkyAlign alignment technology and the included StarPointer Finderscope with a red LED makes aligning a breeze.

Because of its wide 1.7 ° field of view, the NexStar 102 SLT is optimal for scanning large areas of the sky and for superb terrestrial (land) viewing. A wonderful entry to mid-level astronomical scope, with the use of an optional erect image diagonal, the 102 SLT can also be used as a land-based spotting telescope.

What a great buy

By

from Antietam MD  -  Casual/ Recreational

This is a fantastic deal for a refractor telescope. This is my 6th telescope. I have newts and schmits.My best schmit is a c8in and nwt is a 12in. This is my first refractor. I always wanted one but cost for aperture was was too expensive.The slt 102 seemed worth a try. I am so happy I did. I wanted a good grab and go and this is it. I already had a good 2in diagonal and put that in it right away. So i'm not gonna trash the 1.25 that comes with scope.I read bad comments about the star finder scope and have to say maybe these people got a different finder scope. I love mine. Works great! For twice the money you can't do better!

Perfect telescope for anyone

By

from Tampa, Florida  -  Professional Guide

This is a fantastic telescope for a beginner or experienced astronomer. By upgrading the eyepieces and diagonal you'll get a high quality observing instrument. Beginners will have a small learning curve but once you understand the controls you'll be able to tour the universe. I have many telescopes from Celestron and they're are all large 11". This 102mm is highly portable and is a joy to use. I rate is 5 stars!

Spend a bit more and get something else

By

from Perth, WA.  -  Casual/ Recreational

SLT handpiece light flickers on and off after a while, making a torch neccessary for using it. View is very limited with supllied eyepieces. Unstable. Hard to focus due to instability. Basically, the SLT doesn't work, we can never find 3 bright stars that it recognises. It is a kids toy product, buy something else!
