The popularity of our previous short tube refractor models inspired us to go a step further with the introduction of our 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 80 mm models. This short-tube telescope with a fast f/6.5 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. Our new 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.
