With the Celestron NexStar+ handheld controller, you can control the manufacturer's binoculars. Its catalogue stores data on around 40 000 objects and has a user interface in 6 languages (English, German, French, Italian, Spanish, Russian). The handheld controller is compatible with Celestron's equatorial and azimuthal mechanics, requiring firmware updates if necessary.
The handheld can be selected with USB or serial port connection, the difference is in the way it connects to the computer. (A USB/serial converter may be required for a handheld with serial port connection.)
