This Celestron StarSense Explorer DX 102 AZ is a demonstration unit that is complete with manual and all components. It has cosmetic scratches on the exterior but all optics, mechanics and electrical parts are working perfectly.
With the Celestron StarSense Explorer DX 102AZ 102mm f/6.5 AZ Refractor Telescope, exploring the wonders of the universe is as simple as 1-2-3:
1. Dock your smartphone
2. Launch the StarSense Explorer smartphone app
3. Observe the moon, planets, stars, and more
This innovative integration of smartphone and telescope offers beginner astronomers a fast and (more importantly) easy way to discover what's up in the night sky and where to view it. Utilizing similar alignment technology that satellites use when they move out of position, the StarSense Explorer app uses your phone's camera to stream a constant series of images and compare them to an internal database to identify the starfield and determine its location. This "Lost in Space Algorithm" is more precise than typical astronomy apps and does not require a cell signal to work—so you can use it even when you're far off the grid. A holder on the mount, aligned with the telescope, ensures that where the phone is pointed is the same as where the scope is, so that when you follow the onscreen directions to find the object of interest and you look through the eyepiece, it will be there.
