North at the top, east at the left — the sky-chart orientation, as if lying on your back looking up. Altitude rings at 30° and 60°; the rim is the horizon. Dot size follows magnitude; the brighter the star, the larger the mark. The sun is up, so the plate shows the stars where they stand behind the daylight.
