The Celestron SkyPortal Wi-Fi Module converts your personal smart device (smartphone or tablet) into a controller for the Celestron 8SE or 6SE telescopes. The SkyPortal module must be used alongside the free SkyPortal app. The module connects to the telescope via the communication port normally used by the Hand Control remote unit (it looks like a phone jack). The app assists with telescope alignment and identifying objects. This module/app combo is especially helpful if you’re having a hard time finding what you want to observe.
