If you use a PC you can use SkySafari on your phone.
But there is another option. ASCOMPAD is an application that allows you to use a hand controller. You can search the forum for messages about it. It works pretty well. I got it going but don't use it in favor of skysafari on the phone. Many others have, complete with bluetooth version of the controller I believe. Perhaps they can chime in to help you get setup.
