Azimuth is simply the angle of an object in the sky along the horizon. Yes, it's spherical trigonometry but it's not difficult! Check out this video and in just a few minutes you will be able to solve azimuth problems on your own.

You Will Need:

* The latitude and longitude of starting point

* The latitude and longitude of the celestial object

* A calculator with sine, cosine, and arcsine functions

* A chart or map (optional)

* A GPS device (optional)

Step 1: Determine latitude and longitude

Determine the latitude and longitude of the starting point, or observation point, from which you'll calculate the angle. Use L to represent the starting point latitude.

Find latitude and longitude by going to the location with a GPS device.

Step 2: Find object's coordinates

Find the latitude and longitude of the celestial object. Use D to represent the latitude of the point on the earth where the desired object is straight overhead.

Step 3: Find t

Find the meridian angle, represented by t, also known as the local hour angle – or LHA. It is the difference between the observer's longitude and the longitude of the celestial object.

Step 4: Calculate the altitude

Calculate the altitude of the object, called H. Multiply the sine of L by the sine of D. Then multiply the cosine of L by the cosine of D, by the cosine of t. Add these two products and determine the arcsine of the sum.

Step 5: Compute azimuth

Find the azimuth angle, Z, by multiplying the cosine of D by the sine of t, and dividing the product by the cosine of H. Then determine the arcsine of the result, which will give you the azimuth angle.
