OnStep is a DIY computerized GoTo controller for Telescope mounts. This App controls most functions through Bluetooth from your Android cell phone or tablet. The user can align the mount, park/un-park, program PEC, and find and go to celestial objects. These include our Moon, the Planets, and several catalogs: NGC/IC, Herschel 400, Messier, and finally the named bright stars.

Note: To get up and running:
1. This version is for use with OnStep 0.99x11 or later (my current Stable and Dev branches on GitHub.) Configure with checksum disabled on the Bluetooth serial port (default.) This latest version of OnStep also has LX200 protocol fixes and works with some of the most popular Android planetarium Apps (as well as providing better compatibility with PC software.)
2. You must pair the OnStep's Bluetooth adapter to your phone or tablet.
3. Open this App, open it's menu (using your Menu button), select the Bluetooth adapter you just paired, and finally press Accept. This needs to be set just once.
4. To get going... you might want to set your location (Menu/Site Selection.) Then, use the "Home/Align/Park" menu to set the date and time and start an "Align". Once the align is started, select a bright star that you can easily identify from the list and do a "GoTo". Finally, use the N/S/E/W/etc. direction keys to center the star (or you can move your 'scope to it manually) and press the "Align" button. From there, you're free to select objects from the lists and do GoTo's, or just exit and run a planetarium type App to control the mount.
