Walther crater through the astronomical telescope. Moon images.

These images cover a wide enough area of the Moon, where we see large and small craters. The images are processed in Registax.

Sunlight falls on the lunar surface perfectly to show off the physical landscape.

Over the entire area, there are some white parallel streaks, these being rays from crater Tycho.

Many craters are visible in the images. It includes Orontius, Walther and Deslandres.

Of course, the most impressive feature that captures your attention in these images is the huge crater Deslandres (256 km). Despite its size, it can not be detected by simple binoculars, but through an astronomical telescope. This is not strange because Deslandres, even if it is very large, is not quite so deep to be distinguished visually observed when using a small power instrument, and thus is easily confused by the surrounding land.

Deslandres is a remnant of a crater, very affected. It is located south-east of the Mare Nubium on the southern part of the Moon.

In size, it is the second-largest crater on the visible Moon after Bailly crater, which is 303 km.

Other neighboring craters of this huge crater, are Oronţius (122 km), Walther (128 km), Sasserides, Regiomontanus (126 km), Pitatus (97 km) and Ball (41 km). . Embedded in Deslandres crater, are small crater Hell (33 km), and Lexell (63 km).

These images processed in Registax are extracted from a video which can be viewed here.

Walther crater on the Moon.

This is the crater Walther, filmed on March 10, 2014 through an astronomical telescope with a video camera attached. The image is upside down as seen through the telescope.

Walther is a messy crater, like many others situated to the south of the Moon. This crater has a relatively large depth of 4100 meters.


The name is given from Walther Bernhard (June 19th 1430 - 1504) who was a German humanist and astronomer from Nuremberg. He, together with Regiomontanus (which also has a crater on the moon with his name) built an observatory.

Lunar craters filmed through telescope: Walther.

This area is not one that if you observe it will make a good impression to you, given that it is so troubled by serious impacts. Walther (128 km), is one of these craters resulted from these impacts. Its floor is low and smooth to the west, and high with hills to the east.
 
Although the edge is easily distinguished through a telescope, it is highly affected by other smaller impacts and besides this, is irregular from the beginning, when it was created.
 
This crater is filled both inside and outside by its satellite craters.
 On Walther and all his neighboring craters are scattered ejected materials from the crater Tycho (85 km), which have a white colour, making it to shine only on the intense sunlight.
 
Because in these pictures the sun does not illuminate this area from a high angle, we observe on the crater more "disorder" in its appearance, fueled by the shadows of its edge.
Other craters seen here are: Aliacensis and Werner (80/70 km), Purbach and Regiomontanus (118/126 km).

Rupes Recta " the straight wall " or " the sword " on the Moon.

120 frames at 90% best quality, Gaussian, in Registax.

5 frames at 100% best quality, in Registax.

I am sure that features which captivates the viewer's attention in these images are Rupes Recta and Thebit (57 km) crater . The terminal , the boundary between light and dark on this Moon phase , it is left in images , and gets extremely close to the small crater Birt (17 km) , located on the Mare Nubium, west of Rupes Recta .

I said in another article , that the region surrounding Rupes Recta, could be a flooded crater that still preserves its vaguely circular shape after lava penetration in it . We can realize that my opinion is true, by looking at Thebit P (78 km), crater which is in the same measure flooded too that we can barely distinguish its edge .

Rupes Recta , or as it is also called " the straight wall " has a length of 110 km and reaches a height of 300 m In these images , the shadow of this wall is beautifully projected on Mare Nubium , highlighting this characteristic of the Moon hunted by many amateur observers . If the Sun would shine on the opposite side of this wall, would have been appeared as a stright white stripe as a shining sword . Anyway you look at this wall under any lighting conditions , it is a pleasure for any observer whether amateur or advanced.

This sword , viewed as a whole, is made up of several features that make it look like this . The blade of the sword is the " straight wall " after that, the the handle of the sword is made of some mountains, and a flooded crater which has left only half edge. I suspect that it is true after I have analyzed several photos of the area taken by NASA.

The processed video images above are much clearer than the video captures from another article. We can notice the difference in the still image below, in which I labeled each crater.

In these images that are upside down as seen through the telescope, are craters situated on the southern hemisphere of the Moon, where they are numerous, deep and large.

The large "heart" lying on the right side is a heavily eroded crater which was  formed by a major impact, Deslandres, a crater whose features are well brought out in the light on this Moon phase, and in which the terminal is near the crater, at east.

On the uneven floor of Deslandres (234 km), we observe the smaller one, Hell (33 km), whose name fits here, being fully submerged in darkness, as Ball crater (41 km), located at the outer edge on the west of Deslandres.

Other craters visible images are Orontius (122 km), Sasserides (90 km), Walther, Regiomontanus
(128/126 km).

Detailed images of Walther crater by telescope

Walther (128 km), is part of a trio of craters: Walther, Purbach and Regiomontanus (in the middle): Walther is the southernmost of them. It has a depth of 4.1 km.

Walther, in an examination as a whole, it has a round shape but irregular, with central peaks on the floor in the center-east and a flat floor on the west, riddled with many small craters. In the photo below, it's easy to see what I wrote above, but considering that the image is upside down, and the north is where the red arrow shows. This crater is neighbor to the west with the large crater Deslandres (234 km).

Walther A, with a diameter of 12 km, is inside Walther, north of the central peak. On the floor are scattered remains of Tycho crater, located just 421 km from it. But Tycho's rays are scattered across all craters in the region, even far beyond Walther.

Deslandres and the surrounding craters. Astronomical telescope images

These images are very clear, as the camera focus was best. In the pictures here, we have the huge crater Deslandres (234 km) north of the bright crater Tycho.  To view the telescope video of these photos, go here.

A very bright rays of Tycho with high albedo, are spread on the whole region, but these are not seen in the photos because of the Moon phase at that time, when the Sun was at a low angle.

The picture below explains in great detail all craters located inside of Deslandres, and neighbors, as I labeled them each name with color. Images are inverted as seen through the telescope.

As you can see, this area is very rich in craters of all sizes, feature which is common to the south of the Moon. In these pictures, are craters like: Lexell, Sasserides, Walther, Orontius, Hell, Nonius and others.
