Near the great lunar crater Petavius ​​with diameter of 177 km are smaller ones like Wrottesley (57 km), Hase (83 km), Palitzsch (41 km), and Vallis Palitzsch (110 km), Legendre (79 km), which is in darkness in these photos, and Snellius (83 km). North of Petavius ​​is Mare Fecunditatis.

Wrottesley (57 km), lies on the northwest edge of the crater Petavius, and the southeastern edge of Mare Fecunditatis and has a depth of 2.3 km.
    This crater has a circular shape with a slight inward bulge to the south and a system of terraces that line the interior walls. The interior has almost no features, except for a central peak, which rises in the middle of the crater.
       Hase (83 km), lies southwest of Petavius ​​and Vallis Palitzsch and Palitzsch are attached to the edge of the northeast.
Crater rim was damaged and eroded by a long history of subsequent impacts. The most important satellite crater of Hase is Hase D (56 km), a crater that is located at the southern edge. Hase D is definitely deeper than Hase, because as you see in the picture, you can't see the floor of Hase D. The crater floor is in total darkness.
 
       Palitzsch (41 km), and Vallis Palitzsch (110 km), lies south-east of Petavius. Crater Legendre is located southeast of Palitzsch.
 Northeast end of Palitzsch forms the southern edge of Vallis Palitzsch, a lunar valley following the eastern edge of Petavius , ​​a distance of about 110 km. Crater rim is easily confused with the valley itself.
      Legendre (79 km), is a crater with a depth of 2.7 km. Onli the crater edge can be seen in these pictures. The floor is steeped in darkness, and therefore I will speak only on the edge, which is eroded by other small craters,  on the inside and the outside of it.

       Adams is a 66 km crater in diameter and 2 km deep. It was named in honor of three astronomers John Couch Adams, Walter Sydney Adams and Charles Hitchcock Adams.

Snellius and Hase Photos by telescope

Snellius (83 km), a crater is located southwest of the crater Petavius (177 km) on the south-east of the Moon. Hase (83 km)  2.5 km in depth, in these pictures the western edge of the floor is in shadow, and Hase D (56 km), is completely in the dark, the southeast edge being only in the sunlight.
These one of the last pictures taken with my camcorder Sony CX 105 . From January 1, 2012 I have the new camera Sony CX 130.

General Astronomy Video Petavius crater ​​by astronomical telescope

These videos present crater Petavius ​with stabilized images.

In clip number one, Petavius ​​is filmed closer. At 00:03, I slowed down the image, to analyze how the picture goes black by a shadow with a high speed. So in this video can be a unidentified flying object, or a bird could not be focused because of the speed.

The huge crater Petavius ​​floor, is seen a "rille", which starts from the center of the crater, and ends at the edge of the south-west. Overall, looks like a clock showing 20:00.






In clip number two, is Petavius and ​​craters surrounding it, as Snellius southwest of Petavius​​, Wrottesley, lower edge attached to its northwest, Vallis Palitzsch, Hase, and craters at boundary between light and shadow on the right of the video, such as Legendre and Adams, of who we see only the edges are in light, and their floor is dark.

          Petavius ​​(177 km), is a large crater, located southeast of Mare Fecunditatis and has 3.4 km in depth. Attached to the northwest edge is the smaller crater Wrottesley (57 km). At southeast are Palitzsch (41 km), Vallis Palitzsch (a monthly valley near the eastern edge of Petavius that has ​​a distance of about 110 km.), And Hase (83 km).

  Petavius​​'s outer wall is unusually large relative to its diameter, and displays a double rim along the southern and western sides. The convex crater floor was resurfaced by lava flows, and displays a system of trenches called Rima Petavius​​.
Central high mountains are a prominent formation with multiple peaks, which are reaching 1.7 km above the floor. A deep fracture goes from the peaks to the south-western edge of the crater.

The most favorable time to observe this crater through a telescope is when the Moon is only three days. From the fourth day, the crater is almost devoid of shade.

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.
