Cool iphone App for Star Gazing

We featured an iphone Compass app in a past post.  This post is here to tell you about the iphone Star Guide app!

Have you ever looked up and wondered what constellation is overhead?  This iphone app uses the GPS and accelerometer to determine what constellations are in the direction that the phone is facing.  When you look at the night sky, point the phone's camera at the night sky, the screen displays the stars, their names, and constellations!
At SEA~ During the day, we were able to tell our direction by the sun.  When a sailor wakes up the morning, he looks for the sun.  Going from Hawaii to California, the sun should be directly in front of the boat or on the starboard side every morning.  The sun rises in the East and sets in the West.  Daytime orientation.

During the night, we set our intention to sail on a heading in line with a notable constellation.  The Milky Way is bright and bands the night sky.  At dusk, the sailor sets his compass to a line and holds it until the stars come out.
