- "Moon charts are used to study the movement, position, and phases of the moon."
- — Description[src]
A moon chart was a written astronomical instrument. It was used to represent the position, movement and phases of the moon, not unlike a star chart.[2] Astronomers usually used these for research or study. It was quite difficult to interpret one, so one who had difficulty with these charts should have used a lunascope instead.[1] They were sold for 5 Galleons at Wiseacre's Wizarding Equipment in Diagon Alley.[2]
