The Celestron Omni XLT 102 can deliver exquisite views of the moon and planets, as well as a number of deep bright space objects. 

The Omni XLT 102 is a good choice for those primarily interested in observing the moon, planets, and some of the brighter deep space objects. As with any telescope, the potential is subject to your local skies. A four-inch refractor reveals the veil nebula under magnitude 5.5 skies, as well as the spiral arms of the Whirlpool Galaxy under magnitude 6.5 skies. Neither of these sights are practical using even an eight-inch telescope under light polluted urban skies with a limiting magnitude of less than four. The f/9.8 optics of this telescope allow it to reach higher magnifications than fast focal ratio refractors of similar aperture. This telescope should easily handle 180-200X magnification, which many of us find to be a sweet spot for serious planetary observation.

The Omni XLT 102 is supplied with Celestron's CG-4 mount. This medium duty German equatorial mount is more than adequate to the task of handling this telescope. When properly polar aligned it will track your target by simply turning the slow motion control on the right-ascension axis.
