OnStep is a DIY computerized Goto controller for Telescope mounts. This App controls most functions through Bluetooth or Wifi from your Android cell phone or tablet. The user can Configure, Initialize & Align the mount, Park, program PEC, and find/goto celestial objects. These include our Moon, the Planets, and several catalogs: NGC/IC, Herschel 400, Messier, and finally the named bright stars.
