Hi could anyone tell me how i can study the evening sky map , northern hemisphere, i need help?

You can download a program called "Stellarium" it shows you all the stars in the sky at that particular point in time, for instance, you program in the time (22:02 when i'm writing in that comment) and it shows you all the stars that are visible to you at that point in time in the sky, it also has an option to view the constellations, so you know exactly what part of the sky you're looking at when you compare it to the program.
