The Night Sky

People have watched the night skies for millions of years. Some just out of curiosity. Some out of boredom. Some looking for portents, either good or bad.

However, the one thing that they all saw was that there was a pattern in the way the stars revolved around the heavens.

The Night Sky

You need only to look up for a few hours to begin to see these same patterns yourself. Like the Sun, stars rise in the east and set later in the west. Planets follow this same pattern unless they are in a retrograde period, though these periods are not especially common.

What You Need: Star Map/ Planesphere

It is handy to have a star map to help get you oriented.

Star Maps are also called planespheres.

You can find them in hobby stores for a couple of bucks.

What You Need: Flashlight

What You Need: Flashlight

Well, you dont have to trip around in the dark. You can bring a flashlight! Theres one problem here though. It takes your eyes about 20-30 minutes to get acclimated to the dark. Your pupils arent fully dilated until then, so a regular flashlight will never do. Your eyes will have to get acclimated every time you turn it on. To prevent this, your flashlight should have a red gel to protect your eyes. Red saran wrap with a rubber band works great . It works great for catching night crawlers too.
