Astronomy lecture.Western Mare Crisium.Pictures by telescope

These captures of western Crisium sea through the telescope, are presented in another article: Video by astronomical telescope-near Western Mare Crisium.
There are many present craters on this large area, and I will only talk about features that were not discussed before.

We start with Burkhardt crater (57 km), which is located between craters Geminus (86 km), on north, and Cleomedes on south.
Burckhardt is located on two slightly smaller-sized craters on the opposite sides, producing a triple crater formation. Burckhardt E (39 km), is covered by the southwest quadrant of Burckhardt's, while Burckhardt F (43 km), is covered by the northwest quadrant. Crater rim is circular, but somewhat irregular in shape. There is a central peak near the midpoint of the crater floor.

Stucked in the western edge of the crater Cleomedes, is Tralles, and to the east of Cleomedes is the crater Delmotte (32 km), a small crater, whose characteristics are difficult to see because of its position.

Continue to the next photo description below, are craters Macrobius and Tisserand, 64 and 37 km, crater ray Proclus (28 km), and west of Proclus is Palus Somni , an area of 143 km,.

In the third picture below, there are many small craters on the surface of the sea, but also on its edge.
Peirce crater (19 km) with Picard (23 km), are those who are most "into the sea" of Crisium.
Picard's interior has a series of terraces, which seismologists have attributed to a collapse of the crater floor. The lowest point of the crater floor is about 2000 meters below its rim, and has a small hill in the center.

Other craters located further to the edge of the sea are Yerkes (36 km), Lick (31 km), Greaves (14 km), and Glaisher crater (16 km).

Yerkes crater (36 km), it seems interesting, because its inside was almost completely flooded by lava, leaving only a shallow remnant edge above the sea, and the edge is the most visible in west. The floor has a similar albedo with the large Crisium sea, so Yerkes's features are not distinct by surroundings.

About craters Firmicus (56 km) and Apollonius (53 km), I will speak in another article dedicated to them.

Scoresby crater-Moon crater images through telescope

In the photo above, the crater that is completely under the shadow,is Philolaus, which has an area of 71 km. (click on link to see it in light). Mouchez crater of 82 km, is the right of Philolaus.

        About crater Scoresby (56 km), I have not talked, but I mentioned it in other articles, but now I've captured it when the Moon is inclined forward, which makes the crater floor to be more visible.
Scoresby is a Moon impact crater located on the north side. Crater is nearly attached to Challis (56 km) along the northwestern edge (crater Main-56 km, is united with Challis to the north), and is located just north of Meton crater (122 km). Because of its location, this crater appears oval when viewed from Earth, appearing in elliptical shape. It is, however, very circular when seen on top of it.
Scoresby has a depth of 2.4 km, and has an outer wall with sharp edges. It is not marked by other impacts.
Inside is a prominent central peak formation consisting of three mountainous ridges, visible in the photos above.
Other craters in the images below are Goldschmidt and Anaxagoras, W. Bond, Epigenes, and bottom  begins Mare Frigoris.

List of east features of the Moon. astronomy lecture

East of the Moon is marked by several interesting features. Most notably is Mare Crisium, a "sea" visible from the Earth with the naked eye as an isolated spot by other seas, dark in colour.
 Notable craters on the east side of the Moon are Posidonius, Petavius ​​and Langrenus, which are the largest in size.
 Even if it seems that East of the Moon has not too many huge craters, actually there are many  small craters as we can see in the list below.

Space missions on the east side of the Moon.

Apollo 16 (1972) with people on board. Apollo 16 was the tenth mission in the Apollo program with humans. It was launched on 16 April 1972 and ended on 27 April. It was a lunar rover mission and brought back 94.7 kg of lunar soil and rock samples.

Apollo 17 with people on board. EVA activity (EVA). Apollo 17 was the 11th and last  manned mission of the Apollo space program. Launched at 12:33 a.m. on 7 December 1972, with a crew of three members: Eugene Cernan, Ronald Evans and Harrison Schmitt. Apollo 17 landing remains the most recent made ​​beyond Earth's orbit.

 Luna 21 (1973) USSR (Union of Soviet Socialist Republics), has successfully carried on the lunar surface rover Lunakhod 2 on January 15, 1973. It sent back 86 panoramic images and over 80,000 TV pictures.

Ranger 8 (1965) USA - intentionally crashed. Launched on February 20, 1965. Ranger 8 successfully sent 7137 images with a resolution of up to 1.5 m.

Surveyor 5 (1967) successfully landed. It sent more than 19,000 images to Earth, and has conducted more than 100 hours of compositional analysis of the surface.

Wonderful pictures of western Mare Crisium and crater Picard on the Moon

West of Mare Crisium 101 frames at 90% best quality in Registax.



West of Mare Crisium 252 frames at 75% best quality in Registax.



Picard crater 356 frames at 80% best quality in Registax.

In these images, we see Mare Crisium basin with several craters and the mountainous region that forms the southwestern edge of the basin.


Under this illumination angle of the Sun, we see more standout wrinkles on Mare Crisium. These are called Dorsum Oppel (west), and Dorsum Termier, south. These wrinkles are not the only ones on this basin.


Crater Picard (23 km) in these images (better seen in picture 3), seems perfectly round (but oval because of its position on the east Moon), and it's not like that, because it has some edge loops, the highest being on the east. I never saw this crater so prominent like in these images.


Note the flooded crater Yerkes (36 km) located west of Picard, more to the edge of the Crisium basin. Its west wall is high, but as we look to the east, the wall becomes smaller, becoming almost nonexistent.


On the Crisium basin, also observe a crater located south of Yerkes, called Greaves (14 km), which looks like Picard, but smaller in size. Climbing up the edge of the basin, we see its shadow projected onto the plateau, becoming an adorable beauty view. On the western edge of the Crisium basin, are sprinkled more satellite craters of Glaisher (16 km) and Proclus (28 km).


  Continuing to the south of the basin, we see that the collar that surrounds the Mare Crisium is increasingly taller and lace. Here, we see the Thebbutt (32 km) crater, and also satellite craters of some which are on the basin, as Picard and Lick (31 km). The latter is not visible in the picture because is in shadow, south of Greaves.

Image are processed in Registax of a video from which were taken between 101 and 356 frames, merged to form a single image.
