Star Movement Observer

Here's how to make an observer to the Star Movement:

.masking tape

1-Get a cardboard and roll it to make a tube about a meter long and two centimeters in diameter.
2-Fasten the ends with tape.
3-Set the tube on a window sill or in any place where you can see the night sky clearly.
4-Look through the tube opening and focus on a bright star.
5-Fasten the tube with masking tape to keep it in place.
6-Draw the position of the star as seen through the tube. Observe the star for two hours.
7-Use your improvised tube to observe other stars. Do your observation on four consecutive nights.
 And now you can observe the movement of the star.
