Sky Map Help
The main part of each image shows the positions of the objects which are visible in the sky at that time. This includes stars, the Moon, and planets.
It is difficult to draw the whole sky in one go on a flat piece of paper or on the computer screen. This is because the sky is not flat. It is more like a big dome over the observer.
In these images, we have solved this problem by showing the sky inside a circle. The horizon is around the outside of the circle. The bit of the sky that would be right overhead is in the centre of the circle.
