Image taken 22/4/24. Gamma Reiner is an Albedo landmark known as a "Lunar Swirl", one of several known on the moon and easily the most observable from Earth. Thought to be a result of the interaction between magnetism of the moon and Solar radiation. Swirls are flat and cast no shadow. This and crater Reiner are named for Vincento Reineri (1606-1747).
At lower left are Grimaldi (1618-1663) and Riccioli (1598-1671), Jesuit priests who respectively created an accurate map of, and named the features on the moon.
Hevelius is the Latinised surname of Polish astronomer Johann Howelcke 1611-1687). An obsessively keen amateur astronomer he built a roof top observatory which sported a 46 metre(!) long refractor. He made charts of the moon, discovered the moon's libration, and named 7 constellations still in use today.
