Learn How To Read Star Maps
If you are out in your backyard and watching the clear night sky with your binoculars, that is not astronomy. You can actually call that activity as stargazing. However, if you start to follow star maps and track down specific stars or constellations in the sky, that is astronomy.
A star map is a tool used by astronomers to map the night sky. It has been the result of the constant mapping of the sky by observers for thousands of years. The grids in this map allow people to easily navigate the sky for a better observation.
There are some important things about it that you need to know though to make your star hunting experience better.
How to Read a Star Map
If you already have your hands on a star chart, you are now ready to make some serious observations on the sky. But of course, you need a guide on how to use it.
Here it is.
– Find a spot where there is no light pollution. That means a place far from the city lights and where the sky is completely dark. In these places, the stars will be so much visible through your scope.
– Allow your eyes to adjust to the darkness. Once adjusted you will get surprised on how clear and how many the stars in the sky. This time you can start making observations with the guide of your map.
– If you are looking to the South direction, rotate your map so the South is at the bottom. You will see that your star map will correlate to the sky.
-Start by choosing a small portion of your map with one bright star. This will make it easier for you to find your way into the sky.
-Always consider the sky’s movement. If you are out for 6 hours, the stars would have moved 1/4 away from the sky.

There are actually different star maps out there are they have different characteristics. Let me introduce them to you.
