To determine the angle between the equatorial coordinate system and the Milky Way, turn on Starry Night Enthusiast™ software. You will need a protractor for this project. Stop time flow. Turn on the Atlas mode Favourites

Milky Way. You can change its brightness by clicking on Milky Way, which will turn to Milky Way Options.) Next, drag the screen around until you see the Milky Way crossing the celestial equator. Move the celestial equator until it is horizontal. Being careful not to damage the screen, directly measure the angle between the celestial equator and the middle of the Milky Way with a protractor. What is the right ascension of the crossing between the Milky Way and the celestial equator? Now rotate the celestial sphere by 12 h around the celestial equator. Is the Milky Way again crossing the celestial equator? Measure the angle between the two. How does it compare with the previous measurement you made? Explain.
