The highest peaks in this range rise up over 6 km above the basaltic plain. I really like the isolated mountain range to the RHS, Montes Recti, which extends for 90 km and has a width of 20 km. A We are observing the hills obliquely, giving a nice perspective. They rise to a modest 1.8 km above the surrounding plain. The prominent crater on the lower LHS is Bianchini (38 km). The heavily degraded crater just South of centre is Maupertuis (46 km). https://www.visit-the-moon.com/autolycus10-07-1920-37-30 https://photos.on-this.website/wm/JgQRNGMSAXl3lGYpNamZQlwAIiM=/wbl/1459660049/21951_7168497614f9e7a97a9485.jpgAutolycus [color="wheat"][i]VTM H4 | Rukl-12[/i][/color] This image is dominated by crater Autolycus (39 km). The small crater on the rim is Autolycus A (4 km). The rille system Rimae Fresnel can be seen to the left - it is at the foot of the mountain range Montes Apenninus, which is just out of the frame to the left. Though not visible, the Luna 2 “crash site” is just 30 km to the right of Autolycus (at 2 o'clock). The Soviet Luna 2 was the first spaceship to “land” on the Moon. South is up. https://www.visit-the-moon.com/birtr13-03-05-06-10 https://photos.on-this.website/wm/KkA_vBRRNYtO81Jp3IjXkB1eVQw=/wbl/1459660049/21951_80394364651e270a711f1b.jpgBirt_R_13-03-05 06-10-42_PSE_R Mare Nubium contains a diverse range of interesting features. The most notable is Rupes Recta, a mid mare fault also known as Straight Wall. It extends north-south for 100 km. The west-facing slope is up to 2.5 km across, but is not steep as the height only ranges up to 0.3 km. At several points along its length you can see disturbances due to ancient land slides. There are only a handful of similar isolated faults. The small but deep (3.47 km) crater to the west side of the fault is Birt (17 km) and its small companion Birt A (6.8 km). Birt Rille, formally called Rima Birt, is a volcanic channel 1.5 km wide and 50 km in length. The rille arose from a caldera (Birt E, 5 km) at the northern end which sits atop a low dome that is only evident at low angles of lighting. The rille terminates at Birt F (3 km).

As it is a low profile object, rising only a few hundred metres in height above the basaltic plain, it is most easily seen at local sunrise and sunset. The ridge itself is a dark object on a dark background. Dorsa Smirnov is the name given to the Northern-most ridge; the Southern portion is called Dorsa Lister, though together they comprise one single large ridge feature. https://www.visit-the-moon.com/fracastorius-11-09-17-02 https://photos.on-this.website/wm/S6o9cFQ9flvc8PKeH1oN_lVZGDI=/wbl/1459660049/21951_201862660251e26b1531f2c.jpgFracastorius Region at Sunset Rukl-58 Evening is falling on Fracastorius (124 km), with the Eastern half of Mare Nectaris in shadow. The oblique lighting enhances the small hills scattered across the dark floor of Fracastorius, and the East-West rille bisected by craterlet Fracastorius M (4 km) is apparent. The small prominent crater towards the top RH corner, Rosse (12 km) is still caching light on its wall. Though small it is relatively deep at 2.4 km. Many of the craters in the highland region are "satellite" craters of Fracastorius, meaning they are designated Fracastorius A, B, C, etc. The three craters South East of Fracastorius are A (18 km), B (27 km) and G (16 km) respectively from left to right.

The outer wall is poorly defined. For a sense of scale, the bowl-shaped crater Metius (88 km) in the top RH corner is a large crater in its own right. Its interior is deep at 3 km and relatively smooth with several small off-centre mountain peaks, and internal crater "B" (14 km). The neighbouring crater Fabricius (78 km, depth 2.5 km) lies within the perimeter of Janssen. Fabricius has a slightly distorted shape, a linear group of central peaks rising to 0.8 km, and also a second range of mountains North of the central peak. The crater's East and South East walls are well presented for viewing. To the South lies the ill-defined crater Fabricius A (45 km), also within Janssen's boundaries. One of the most notable features of Janssen is the arc-shaped system of rilles, Rimae Janssen. They extend across a large unnamed depression within the Southern region of Janssen, perhaps encompassing half of the area of the walled plain. The nicely formed Lockyer (34 km, 3.8 km deep) straddles the Western wall of Janssen.

The crater floor is a relatively dark basaltic plain dotted with a number of small hills and craterlets. The two largest are Fracastorius L (5 km) and M (4 km) which bisects the rille. There is a particularly bright craterlet (2 km) at the North East corner of Fracastorius.

Whilst IR is less sensitive to atmospheric turbulance, I have found that in practice resolution is slightly better in red light. There is also less tonal variation in IR vs red. Arzachel is relatively deep at 3.6 km and the off-centre central peak rises to 1.5 km above the floor. Being a relatively young crater, there are few impacts on its floor or walls. Arzachel A (10 km), the largest, sits between the central peak and the curved rille Rimae Arzachel, which runs for 50 km. The shadow shows that the floor east of the rille has a lower elevation than the west side. A further less pronounced rille runs along the inside of the south east wall. The craterlet south of "A" is "K" (4 km). An odd shaped craterlet "H" (5 km) overlays the southern tip of the central mountain. The larger of the pair of craterlets at the north end of the curved rille is "T" (3 km). There are a number of small hills dotted around the floor. On the western wall there is a partil crater in shadow Arzachel B (8 km) and a smaller crater "C" (6 km) on Arzachel's rampart.

It has a very prominent central mountain that rises to 2.0 km above the floor. The floor itself has few craterlets and a number of small hills. Ancient landslides have transformed the crater walls which are very broad. The crater on the northern wall is Piccolomini M (23 km). This image was captured in IR with local Sunset approaching.

It is bisected by crater Hyginus (10.6 km), which is actually a caldera of volcanic origin. It is one of the few 'craters' of non-impact origin. The rille and crater were probably formed by magma that collected under the surface, forming a 'lava tube' which eventually collapsed, forming Hyginus and the many smaller craters dotted along the rille. This is a relatively "young" feature on the Moon. The Northern end of the complex rille system Rimae Triesnecker is visible in the top of the image. https://www.visit-the-moon.com/vallisalpes10-06-2122-37-46 https://photos.on-this.website/wm/mbemxU0kW5P3KRaT76qbSw4rVpI=/wbl/1459660049/21951_9944513194fa11380484f3.jpgVallis Alpes (Alpine Valley) [color="wheat"][i]VTM H2 | Rukl-4 Rukl-12[/i][/color] Vallis Alpes, also known as 'Alpine Valley', is a broad flat valley that cuts through the Montes Alpes mountain range, linking Mare Imbrium and Mare Frigoris to the North. It is 10 km across at its widest point. The valley floor is relatively flat having been flooded by mare material. A narrow sinuous rille that runs down its centre is just visible here. https://www.visit-the-moon.com/lacusautumni10-09-2602-45-16 https://photos.on-this.website/wm/p7MTogvVCSTyEUeKdIdK-XdSHmE=/wbl/1459660049/21951_17748090434f9e7af2b3215.jpgLacus Autumni & Mare Orientale The dark complex curved feature on the LHS is Lacus Autumni (Lake of Autumn), a lunar mare that lies on the western limb. It is semicircular but strongly foreshortened here. The larger long dark feature closer to the limb is Lacus Veris, an arc shaped mare that lies on the east side of Mare Orientale and partially encircles it. Mare Orientale, a large circular impact basin, is just visible here as the dark line along the limb with the western ring of mountains being nicely silhouetted on the lunar limb. This mare is located on the far-side of the Moon and is only visible from time-to-time. https://www.visit-the-moon.com/marehumoldtianumir12-05-31-21-22 https://photos.on-this.website/wm/f41bKVWp84keehhvxWlXzBOu5W4=/wbl/1459660049/21951_11761967804fcaa7875224d.jpgMare Humboldtianum Rukl 7 Mare Humboldtianum lies on the north eastern limb of the Moon and under favourable libration, as in this case, can be seen in its entirety. At other times it vanishes to the far side. The mare has a diameter of 273 km; it is of course extremely foreshortened. Viewing from the side shows that it is an enormous basin. In particular the mountains along the eastern rim can be seen in profile and would resemble mountain ranges encircling Mare Imbrium, which we only see from above. The heights extend up to several km.

A number of wrinkle ridges appear to radiate out from the crater. Wrinkle ridge Dorsum Zirkel extends towards the top LHS for a distance of 210 km. Of particular interest is the flooded ghost crater Lambert R (55 km) immediately South of Lambert. Only visible at local sunrise or sunset, this ancient crater was buried when Mare Imbrium was flooded 3.5 billion years ago. Upon cooling and shrinking, the basalt deformed to reveal the form of the ghostly submerged crater. A number of isolated mountain massifs are dotted through the field with Mons La Hire (10 x 20 km) on the LHS casting a very long dramatic shadow. https://www.visit-the-moon.com/delambre-cr15-05-25-08 https://photos.on-this.website/wm/FBEi8JHU_ADa93uF36xBG_ASm3c=/wbl/1459660049/21951_133653770055796d6241310.jpgHypatia C Region This interesting region sits on the Southern "shore" of Mare Tranquillitatis, East of Delambre and North of irregular crater Hypatia (bottom RH corner). The crater feature to the left of centre is Hypatia C (15 km). The region contains a number of odd-shaped craterlets and a curved crater chain, which is not named. The broad rille, Rimae Hypatia, runs across the Northern edge of the field. It is one of many that border Mare Tranquillitatis. The iconic Apollo 11 landing site lies North of the rille and just outside this image.

Rimae Posidonius is the collective name for system of rilles that crisscross the crater. The rille running along the Western wall is highlighted by the oblique lighting. Variation in Western wall height is evident from the cast shadows, with a portion of that wall also missing. Crater Chacornac (51 km) to the South East is in full shadow with only its Western rampart being illuminated. Mare Serenitatis occupies the left half of the image, and with this illumination the wrinkle ridge system Dorsa Smirnov is thrown into relief.

Directly North of the prominent crater Aristarchus (40 km) there are a number of small rilles of volcanic origin "Rimae Aristarchus" that radiate out into Oceanus Procellarum. One of the few isolated faults, Rupes Toscanelli (length 70 km) can be seen ~60 km North of Aristarchus as a dark line running North-South. The oblique lighting also reveals a number of small volcanic domes that are encircled by the dark Vallis Schroteri. The ancient horseshoe-shaped flooded crater Prinz (47 km) is located near the top RHS together with several large isolated mountains, Montes Harbinger.

[color="wheat"][i]VTM H4 | Rukl-12 Rukl-22[/i][/color] This wide field image captured with the DMK 4 takes in the Eastern side of Mare Imbrium. Flooded crater Archimedes (83 km) is the dominant feature and the largest crater within Mare Imbrium. It has a depth of 2.1 km and the two largest internal craterlets, T to the left and S to the right, are both 3 km in diameter. The mountain range Montes Spitzbergen lies to the North of Archimedes, together with several scattered isolated mountains. Autolycus (39 km) lies to the East (right) in part shadow; it is a deeper crater with a depth of 3.4 km. Luna 2, the first probe to reach the Moon in 1959, landed (crashed) between Archimedes and Autolycus. Imagine a line between the crater centres and 2/3 the way from the larger crater wall to the smaller crater wall. - there it is! Aristillus (55 km) sits in the top RH corner. This crater has beautiful terraced walls and a complex group of central peaks rising up to 0.9 km above the crater floor. It is a deep crater at 3.4 km. Aristillus, which is a relatively young crater, is the centre of a ray system that is apparent at Full Moon. The basalt plain between these three craters is called Sinus Lunicus, though it is simply part of the same basaltic plain as the surrounding Mare Imbrium. A crescent-shaped flooded crater remanent, Spurr (13 km) can be seen approx. 40 km South East of Archimedes. As is common on all mares, a number of wrinkle ridges can be seen, here running North-South.

It is fitting that the central mountains look like two triangles! You can see the shadow of the central peaks projected onto the Western rim. There are actually three central peaks, with the tallest pair rising over 3 km above the surrounding floor. The topography of the complex crater wall is clear, and contributes to the "triangular shadow" of the central peaks. The crater is also very deep, at an estimated 5 km. The lack of internal impact craters suggest that it is a relatively "young" crater. Pythagoras resembles Copernicus. https://www.visit-the-moon.com/copernicus10-06-2122-20-10 https://photos.on-this.website/wm/DzAKYDeQKso7x5sTrhYrGNNY5ZI=/wbl/1459660049/21951_2699948004f9e7aea69afc.jpgCopernicus at sunrise Copernicus (93 km) is a classic crater, and one of the youngest on the Moon at ~800 million years, hence the lack of internal impacts and clean features. The terraced walls, which rise 900 m above the surrounding plain, show signs of prehistoric landslides. In addition to the three main central peaks, the crater floor is dotted with small hills, which may be volcanic. The crater is 3.7 km in depth and the central peaks rise 1.2 km in height above the crater floor. Resolution down to ~1 km, South is up. https://www.visit-the-moon.com/ngc5139-omega-cen-in-centaurus https://photos.on-this.website/wm/uDkqDzTeHZ0jj8PA5AXaOUbJz98=/wbl/1459660049/21951_171797902455bc876a3ce45.jpgNGC5139 in Cen Globular cluster &omega; Centauri is one of the most impressive deep sky objects. In a large telescope the golden colour of the star system is quite evident. Whilst Becvar lists d=23", outlying stars extend out to at least 60". Posted images often present a burnt out central region, and often white, which does not resemble the view through a telescope. Careful processing here maintains star resolution to the core and presents the generally reddish colour that can be seen in most globular clusters.

Here the rille is up to 5 km across and ~130 km of the overall 220 km length is shown. It is an example of a graben - a subsidance between two parallel faults. It is interesting to see how the subsidance has occured after the other features were established except where the rille has been tectonically disrupted just next to the group of mountains north of centre. These features resulted from shrinkage of the basaltic plain. For reference, the crater in the top LH corner is Silberschlag (13.4 km), it is a bowl-like structure of depth 2.5 km. The image was captured in IR, and the rings within the larger craters are an artifact more common in my IR imaging for some reason. The crater just north of the rille is Silberschlag A (7 km) and the larger crater in the bottom LH corner is Whewell (14 km).

The eastern section of the very broad wall is also well presented. The crater does have a ray system and so it is one of the (relatively) young craters. There are few impacts within the crater, the largest being Petavius A (5 km) just south east of the central peaks. One of the most unusual features of this crater is the rille system; the most notable rille looks like a spoke extending from the central peaks to the western rim, length 80 km. A lesser rille extends north from the cenral peaks and a much finer rille obliquely crosses the east side of the crater. The distorted crater on the western rim is Wrottesley (57 km). A 110 km long valley, Vallis Palitzsch, hugs the eastern wall of Petavius. The dark basaltic plain in the top LH corner of the image is the the southern reaches of Mare Fecunditatis.

A volcanic feature, Vallis Schroteri is a large valley by any measure, with a maximum width of 10 km, a total length of 160 km and a maximum depth of 1 km. A narrow rille runs down the length of the valley. Considered a difficult target, excellent sky conditions allowed me to capture the Southern end of the elusive rille in the wide part of the valley known as the "Cobra's Head". https://www.visit-the-moon.com/jherschelr13-06-20-21-59 https://photos.on-this.website/wm/Crjv_31jpyCCtkV1z1qS5ji9f4g=/wbl/1459660049/21951_82782844051e6841acd358.jpgJ.Herschel [color="wheat"][i]VTM C5 | Rukl-18[/i][/color] J.

It has paid off in this early (lunar) morning image of volcanic formation Mons Rumker. This cluster of ~30 domes located on Oceanus Procellarum rises to 1.1 km above the basaltic plain. The structure is roughly circular with a diameter of 70 km though it is considerably foreshortened as it is close to the Northwestern limb. The domes are highest to the South. As the Sun rises, this strange plateau disappears into the surrounding basalt plain. Unlike some other lunar domes, the vents imaged by orbiting satellites are not apparent.

They are long extinct but preserve their features including central caldera that once spewed out lava. The domes are very shallow and can only be imaged at very low incident light angles. The dome shown at in the center here, near local sunset, is Pi (π) Milichius. Its central caldera pit is ~1 km in diameter. Although π Milichius is 10 km in diameter, it only rises to ~230 m. In contrast, the most prominent crater, Milichius (13 km) has a depth of 2.5 km. Milichius A (9 km) lies at the top of the image.

Most rilles are in maria or flooded craters. It looks like a highway! It extends outside this image in both directions. Apparently the lunar magnetic field (which is very weak) is unusually strong in the vicinity of the Rima Sirsalis. The prominent crater in the bottom of the image is Sirsalis (42 km); it partly obliterates the older Sirsalis A (49 km). Crater Sirsalis J (12 km) bisects the rille. A less prominent rille wraps around Sirsalis A, and towards the bottom left of the image a faint rille is just apparent. South is up. https://www.visit-the-moon.com/ngc6656-m22-in-sgr https://photos.on-this.website/wm/igei3x8FpI_v_q7Ew82ehEDs0uY=/wbl/1459660049/21951_117399687155bcaebc8f425.jpgNGC6656 (M22) in Sgr https://www.visit-the-moon.com/photo18626223.html https://photos.on-this.website/wm/_E8XZXSsMLUp5d4tivJaGxUlRS8=/wbl/1459660049/21951_149371043351e26e74e81a2.jpgCatharina_R_13-04-01 07-21-45_PSE_R https://www.visit-the-moon.com/alphonsusir0021-12-04-13-03 https://photos.on-this.website/wm/tgZS1xqHec1Txqj7L9F_ync4iJI=/wbl/1459660049/21951_138329664551e7c6a872081.jpgAlphonsus_IR_0021 12-04-13 03-29-31_PSE_R Alphonsus (119 km) has a single central peak that rises to 1.5 km above the crater's floor. The floor is criss-crossed by a system of rilles, some of which can be seen in this image. The most apparent run north-south on the east side. One of the most interesting features of this crater is that several of the small craterlets are encircled by dark patches up to 10 km in diameter which may be of volcanic origin, though this is not certain. Ranger 9 (crash) landed ~15 km north-east of the central mountain in 1965.

The floor of the crater is flooded, with two internal craterlets apparent and one in the centre just percebtible (<1 km); the largest is Marius G (3 km). For size reference, the crater to the RHS of Marius is Marius E (6 km). The “Marius Hills” are up to a few km across & average 200–500 m in height. They are believed to be of volcanic origin. There are many smaller domes with diameters in the 1-2 km range. In this image they continue beyond the terminator. The domes are only visible just near sunrise or sunset. https://www.visit-the-moon.com/drawing-langrenus-obserresized https://images.on-this.website/21951_119993475658a951a945f97.jpgDRAWING Langrenus OBSER_Resized https://www.visit-the-moon.com/photo25837964.html https://photos.on-this.website/wm/uY-h3Y5B--nAKhr6yZLDlKJ7qgY=/wbl/1459660049/21951_725577875561a3f8811078.jpgAlfraganus_R_15-05-25 09-10-28_PSE_R_2 https://www.visit-the-moon.com/ptolemaeusr13-03-05-05-58 https://photos.on-this.website/wm/2bAVvTrxE8Y6qL90qBbGNFRJZ6A=/wbl/1459660049/21951_48279873451e7c6b9aa904.jpgPtolemaeus_R_13-03-05 05-58-20_PSE_R https://www.visit-the-moon.com/blancanusr15-04-10-21-25 https://photos.on-this.website/wm/I5m55azYfrEYejVuWnjlFQOL1Ww=/wbl/1459660049/21951_1071416799561a406c42d66.jpgBlancanus_R_15-04-10 21-25-38_PSE_R_2 https://www.visit-the-moon.com/ngc7078-m15-in-peg https://photos.on-this.website/wm/RJcHgO13egNeyPgUvzy2IipWKlM=/wbl/1459660049/21951_127050074855c1ef0968610.jpgNGC7078 (M15) in Peg https://www.visit-the-moon.com/photo18626263.html https://photos.on-this.website/wm/cyVPu765JDCmCKS6T6G5l9uoXi8=/wbl/1459660049/21951_108796146651e2711e376a2.jpgScheiner_R_13-04-05 07-35-05_PSE_R https://www.visit-the-moon.com/muller-muller-crater-chain-gylden https://photos.on-this.website/wm/OOUJy8CLwjX5RNyD0UXOqLZFZnU=/wbl/1459660049/21951_153733900053e228ce2e1af.jpgMuller & Muller Crater Chain & Gylden https://www.visit-the-moon.com/photo24527940.html https://photos.on-this.website/wm/cTdQ_Zi4ZNvrLHRcGJD73jNBqeo=/wbl/1459660049/21951_19587599035576d681a19a5.jpgBlancanus_R_15-04-10 21-25-38_PSE_R https://www.visit-the-moon.com/ngc6802-m55-in-sag https://photos.on-this.website/wm/xnusjclK53uvZCkmd2QIPTnSkH0=/wbl/1459660049/21951_89741243655bd882da6010.jpgNGC6802 (M55) in Sgr https://www.visit-the-moon.com/atlas-herculesr13-05-28-03 https://photos.on-this.website/wm/pQ4-B_gQJ6xL3KZHhjDq58uwNaw=/wbl/1459660049/21951_169955950351a3d9980842b.jpgAtlas Hercules_R_13-05-28 03-31-55_PSE https://www.visit-the-moon.com/photo25837981.html https://photos.on-this.website/wm/8WVdTS_eIaatc8dlFwHBnx8Oa40=/wbl/1459660049/21951_1027529696561a3fb2d69dd.jpgAristoteles_R_15-05-25 09-22-00_PSE_R_2 https://www.visit-the-moon.com/photo18626230.html https://photos.on-this.website/wm/CkL27ZH4QrXqXq2yJ0RCUeMbiI8=/wbl/1459660049/21951_8394778651e26e882f8dc.jpgTheophilus_IR_12-07-08 02-00-27_PSE_R https://www.visit-the-moon.com/maksutovcassegrain https://images.on-this.website/21951_178945408556164c1abaaec.jpgMaksutov_Cassegrain Milan occasionally observes the Moon with this 350 mm Maksutov-Cassegrain housed at the Štefánik's Observatory.

It is located on Mare Nubium and has a large surronding rampart with the impact of ejecta extending for over 100 km beyond the crater wall. There are numerous crater chains due to the impact that created Bullialdus.The crater is deep at 3.5 km and contains a complex cluster of central peaks which reach up to 1 km above the crater floor. A broad Flat valley, "Bullialdus W" can be seen running West on the left side of Bullialdus. There are a number of nearby flooded craters, the most prominent one being Lubiniezky (44 km) to the left. Its floor is peppered by craterlets from the Bullialdus impact. Possibly the most interesting is Wolf T (27 km), which appears to be filled to the brim creating a plateau rather than a depression. Wargentin (South West Region) is the most prominent example of this type of crater. Gould (34 km), towards the top RH corner, is another nearby example of a flooded crater, which is missing the South-East arc of its wall. It is crossed by an ejecta crater chain. Flooded crater Kies lies just south of Bullialdus but is not in this image, it has its own image. There are numerous wrinkle ridges in the RHS of the image.

Nevertheless the region is very interesting. The full 300 km length of the broad rille, Rima Hesiodus, extends from crater Hesiodus (43 km) in the top RH corner across to flooded crater Capuanus (60 km) on the LH side. The rille is an example of a graben, a valley created by subsidence between two parallel faults. Crater Hesiodus has a 5 km craterlet in its dead centre. The neighbouring crater Hesiodus A is in darkness here, hiding its strange double crater interior, which is much like the smaller crater Marth (7 km) located just North West of the Western end of Rima Hesiodus. The dark crater near the image centre, Cichus (41 km) has a crater Cichus A (11 km) right on its rim. Just North East of this feature is the flooded and degraded crater Weiss (66 km); its floor is scattered with small hills which can be seen with the low angle of illumination.
