Named after their venerable GoTo system, the Celestron NexStar 102SLT 102mm f/6.5 Refractor Telescope is a complete platform for making observations of the moon, planets, and bright deep-space objects such as binary stars, star clusters, galaxies and nebulae. The combination of large aperture and shorter focal length translates to a fast f/6.5 focal ratio making this iteration of the NexStar telescope series ideal for wide-field astrophotography or making detailed images of the moon. Celestron includes two eyepieces and a diagonal, plus an unmagnified finderscope and stainless steel adjustable-height tripod.
Controlling the motorized single-arm fork mount is the NexStar computer hand controller. Set up is made easy through the use of several alignment procedures, and keeping objects centered is accomplished with variable tracking rates. Packed with over 4000 celestial objects in its database and expanded information on over 100 of those objects, users have the ability to add 99 of their own objects to help customize their experience. For fast observation sessions, simply choose Tour mode the NexStar build a selection of the best objects for that date, time, and location and automatically go to those objects.
Transform your smartphone or tablet into a wireless controller for your computerized telescope with Celestron's SkyPortal WiFi Module. It plugs into the Hand Control or AUX port and begins to generate it's own WiFi signal to directly connect to your mobile device without the need for a router. Since it uses the telescope's power there are no batteries, plugs, or cables required.
The SkyPortal module works in conjunction with the free SkyPortal mobile app available for iOS and Android devices. The app features a database of over 100,000 objects with astroimages and audio descriptions of hundreds of them including the history, mythology, and key features of them. It can assist with the telescope alignment and if you hold the screen up to sky, it will identify the objects based on your location, date, and time. If you don't know what you want to look at, the SkyPortal app will take you on a guided tour.
