Today's full moon, called a worm moon, photographed with a telescope and several images stitched together into one image.
At a full moon, the sun illuminates the lunar surface directly from the front, which hides shadows and makes it more difficult to distinguish topographical details such as craters and mountain walls. The use of HDR photography (High Dynamic Range) and stacking (combining many images) is therefore crucial to highlight geological contrasts and mineral variations that are otherwise lost in the bright light.
Geological details at a full moon
Beam systems: At a full moon, bright beam systems appear most clearly, for example from the crater Copernicus. These consist of material (ejecta) that was thrown out during a meteorite impact.
Albedo and minerals: The contrast between the light, calcium-rich highlands (anorthosite) and the dark, iron-rich oceans (basaltic maria) becomes extremely clear. By saturating the colors in an HDR image (so-called "Mineral Moon"), chemical differences in the soil can be visualized.
Bright Craters: Craters with high albedo, such as Aristarchus, shine brightly and can even be seen with the naked eye.
