On these pages I do "moon walks" on the basis of my own photos. In other words, I try to name the objects on my lunar photos to get to know the moon better. Maybe these pages will help others to get to know the moon better as well...
On this and further pages, I present selected surface elements (maria, craters, mountains) on the moon, or combinations of these in alphabetical order, thus, as a small "moon encyclopedia." Some of the photos are repeated because they contain several interesting objects; the current objects are labelled in yellow. The photos are rotated by 180 degrees or mirrored so that they correspond to the normal visual impression, but they are often somewhat skewed. I hope to be able to replace some photos with better ones in the course of time...

On this page and on a second one, I present landscapes on the moon, surface elements (maria, craters, mountains), or combinations of these in alphabetical order, thus, as a small "moon encyclopedia." The photos are rotated by 180 degrees or mirrored so that they correspond to the normal visual impression, but they are often somewhat skewed.
Note: The description of the general elements of the moon surface can be found on page Walking the Moon with my own Photos - Overview.

Grimaldi is a walled plain at the southwest edge of the moon with 173 km diameter and 3200 m depth (Spix; 222 km according to VMA). At full moon, the crater appears as a dark spot. I mostly photographed it too early and thus, did not really catch it. For space reasons, I only present photos with labels.

The crater Hercules can already be seen a few days after New Moon and, together with Atlas, appears as a pair of craters. Hercules is 69 km in diameter and 2300 m deep (Spix; 70 km and 3200 m according to VMA). The following photos demonstrate how the terminator moves to the west.

Sinus Iridum (Rainbow Bay) is a semicircular bulge in the northwest of the Mare Imbrium with a diameter of 250 km (Spix). According to Spix, it is the remains of a crater; the crater rim is called Montes Jura (Jura mountains). When the Jura mountains appear at the terminator and are lighted by the sun while still extending "into the darkness", this phenomenon is called the "golden handle."
The following photo sections show the Jura mountains (top left) and the craters Plato (top) and Copernicus (bottom). Above and to the left of Copernicus you will find the Montes Carpatus. Note the "golden handle"!

One day later, the terminator has left the Jura mountains. The following section from February 26, 2018 (three days after half moon) has been made lighter and shows again the Jura mountains (top left) and the craters Plato (top) and Copernicus (bottom). Above and to the left of Copernicus you will once again find the Montes Carpatus.
