Spyglass - Great navigation app for iPad

Spyglass is a great navigation app that blends together milspec compass and sextant features on your iPad 2. You can using it as an optical range finder, angular calculator,GPS tracker, stars and maps.

The app turns my iPad into a digital spyglass with heads-up display. Track positions of the Sun, and stars with arc second precision, and works great. Waiting for adding the video recording feature soon.
