The great conjunction 2020 is the closest approach of Jupiter and Saturn in nearly 800 years. The evening of the Winter Solstice found them 6' 20" apart in ou sky. Physically they are over 450 million miles apart.

Another trip completed around this big bright boi today, managed to get about 25 images to stack in Autostakkert for the disk detail, and another overexposed one for the shine, so this is a composite image.
Sunspots have moved around slightly as the sun rotates, and they are a little clearer, always mad to me when I see they've moved!

The mountain chains that surround the Imbrium Basin are endlessly fascinating, for their variety, beauty and now, human history. I focus in this photo on the mountains that define the Eastern and Southeastern bounds of the Imbrium Basin.
The chain of high, sharp peaks that arc upwards from the lower left are the Montes Apenninus. These formed immediately when a proto-planet gouged the enormous Imbrium Basin into the face of the Moon. Rising up to 14,000 feet, the mountains form an arcing chain that gradually bends from east to northeast, ending at Promontorium Fresnel. Here, there is a gap where the Mare Imbrium to the west joins the Mare Serenitatis to the east. At the north end of this gap in the upper right of this photo, lie the first peaks of another mountain chain, the Montes Caucasus (perhaps a feature of an upcoming image).
Two craters are prominent in the upper left, within the Imbrium basin. Along the upper margin, left of center is Autolycus crater. On the left border, spilling out of the frame, is the much larger Archimedes crater. A field of rubble (ejecta from the impacts that created the craters) and many small craterlets connects the two craters. A larger similar field extends southward along the left side from Archimedes. If you look closely, a fissure, or rima, extends from Archimedes back towards the Apennines. This is Rima Archimedes.
The area just inside the arc of the Montes Apenninus shows many other rimae. Southeast of Rima Archimedes in center left, the broad Rima Bradley can be seen running diagonally from southwest to the northeast . It ends in a smooth region where lava filled the low valleys of the Imbrium Basin. this area is known as Palus Putredinis (gross, right?). If you extend the trace of Rima Bradley toward the upper right, you see another series of cracks that run from Palus Putredinis to the area inside Promontorum Fresnel and the gap connecting Mare Imbrium and Mare Serenitatis. These are the Rimae Fresnel.
The real star of the rima show here lies in a small gap between the outer and inner ridges of the Montes Apenninus. Lying just above center, Rima Hadley, aka Hadley Rille, snakes northward out of the Montes Apenninus, through a narrow valley, past a small crater, and then abruptly turns westward towards Palus Putredinis at the foot of Mons Hadley. Many of us can remember those days in July and August of 1971 when Apollo 15 landed in the small flat between the 14,000 ft. peak of Mons Hadley and the 1000 ft. chasm at the bend of Hadley Rille. This was the first mission where the crew used the lunar rover to explore their surroundings. Quite a mission!
The lower right corner of this image is filled with a region of low hills and hummocks known as the Montes Haemus. This is an area where debris of the Imbrium impact flowed out over the surrounding terrain, and filled space between the newborn Montes Apenninus and the old basin rim of Mare Serenitatis. Many such areas surround the Imbrium Basin, mainly to the south, southeast and east, suggesting that the proto-planet impacted from the northwest.

Photographing the last full Moon of 2016 was much fun because I had a pretty clear sky the whole night. I had an idea what to do with this shot so I think all played in my favor. This is how the Moon looks like when you enhance the colors of the surface. It has blue, cyan, purple and brown colors that represent the elements of titanium and iron on the surface of the Moon. It’s surely not a big grey ball on the sky.

Taken on 25th February while the Moon was 77% illuminated Waxing Gibbous. Taken with a 10" Dobsonian Telescope with 2x Barlow and Canon 1100D. Shot using Backyard EOS, at 5x magnification. By the time I had set everything up for shooting some up-close lunar stuff, the cloud started rolling in, so this was shot through thin cloud.
4000 frame video shot, the best 1000 frames were stacked using Autostakkert! 3 Beta. Wavelets sharpened in Registax 6 and final tweaks made in Fast Stone Image Viewer. The edges were cropped slightly to remove stacking artifacts. I really love the sharp shadow created by Cape Laplace on the edge of Sinus Iridum

The atmosphere became very still for about 20 minutes on this night. The raw video coming from the camera had so much detail.
This from 16 30 s SER files taken with a ZWO ASI224MC camera with 3x Barlow and a ZWO UV/IR cut filter through the C14 at Cerritos College. I used FIreCapture to take this data. SER files were used to create stacks of the best 35% of about 600 frames in AutoStakkert, and those stacks were processed in PixInsight. The resulting images were registered and derotated in WinJUPOS, with the result undergoing some final tweaks in GIMP.

The January 2019 Total Lunar Eclipse taken from Arlington, TX. This image is a composite of processing the data twice, once focusing on the background sky, and once focusing on the moon details. There were thin clouds on and off throughout the night, which may have led to the radiant glow around the moon.

This is image was captured using a 60mm Hydrogen-alpha (Hα) telescope. It is showing the Sun's chromosphere.
There were very interesting features on August 18, 2022. At the top is a filament in the shape of a circle. It is also raised quite a distance above the chromosphere. Going down to the right thee is a very large and thick filament. Just to the left of that filament is a sunspot (AR3081) surrounded by a plage.

"Rupes Recta, Ancient Thebit, Huygens’ Sword and Rima Birt"
This photo is a northward extension of my previously posted shot of Deslandres Crater. The focus of this photo is the region that occupies the center of the image. First, let me outline the lay of the land. Deslandres Crater and the adjoining Regiomontanus Crater are in the bottom right corner of this image. Moving up the right side of the image, Purbach Crater sits about 1/3 of the above the bottom. Higher up, Arzachel Crater can be seen. Above and left of Arzachel, near the top, is Alpetragius, sporting an oversized central peak. The dark area on left top and down the left side is Mare Nubium. At bottom left is Pitatus Crater.
Moving toward the center from the right side, is Thebit crater, inside from both Arzachel and Purbach. It sits on an arc of hilly terrain that appears as a bay connecting to Mare Nubium. If you look closely, you can see that the arc of hills continues out into Mare Nubium, in the form of curving wrinkle ridges that circle all the way around to meet again the arc of hills upon which Thebit sits. This circle, formed from the arc of hills and the wrinkle ridges, bears memory of an old, unnamed, ruined crater that is unofficially called "Ancient Thebit". The 57-km-wide crater Thebit sits on its battered eastern rim.
The interior of Ancient Thebit holds several features of interest. Most notable is the long black linear feature that cuts across the floor of Ancient Thebit. This feature often evokes wonder from new observers of the Moon. “What is that straight black line?”, they ask, realizing this is something unusual. What it is, is the best example of a geological fault to be found on the surface of the Moon. It is called “Rupes Recta”, the Straight Wall. Close examination reveals its nature. First, it is almost, but not quite straight. It casts a shadow when illuminated from the East, as in this photo. That indicates it is higher on the east side than on the west. Its height is estimated between 250 and 450 meters. It is 120 kilometers long. To the east of the Straight Wall, the floor of Ancient Thebit is rough, hilly and peppered with craterlets. To the west of the Straight Wall, the terrain is smoother, and sparsely cratered. The western floor of the ancient crater was flooded with lava, as was Mare Nubium. It is likely that the weight of the flooding of the old crater floor caused the western side to subside, and then break downward along the line of the Straight Wall.
At the southern end of Rupes Recta, the fault terminates in an area of low mountains. These mountains are called by some “the Stag’s-Horn Mountains” for that is what they resemble. The entire feature comprised of Rupes Recta and the Stag’s Horn Mountains is known as “Huygens’ Sword”, with the mountains forming the hilt and guard of the sword, and the Wall the blade. Take a look for yourself. What do you think?
West of the wall, the 17 km wide crater Birt stands pretty much alone in this part of the ancient crater floor: the 7 km wide Birt A crater hugs its southeastern rim.
Originating immediately to the west of Birt crater and running northwestward, a second elongated feature can be seen running roughly parallel to the Straight Wall. The northernmost end of this feature arises on the top of a somewhat darker, possibly dome-shaped structure sited nearly on the edge of Ancient Thebit. The southernmost end seems to terminate abruptly in a circular pit just beyond the shadow of Birt’s western rim. This elongated fissure is Rima Birt. It is likely a relic of the volcanism than flooded this part of Ancient Thebit. Because the tiny pit at the Rima's northern end is located near the rim of Ancient Thebit, one can imagine speculate that the fractured rock of the old crater’s rim allowed lava fountains to erupt onto the lunar surface, producing a dome, collapse pits, a lava channel, and pyroclastic deposits. If you recall the lava fountains and rivers of lava you saw in videos of the recent Kilauea eruption, you might be able to imagine the scene at the head of Rima Birt, except the Rima Birt eruption poured out enough lava to fill the Ancient Thebit and break the crater’s floor. That would have been a spectacle!
Photographed in the early evening of February 2, 2020, during a period of outstanding seeing that coincided with the first half of the Super Bowl.
This photo has more noise than other shots from this day, so it looks granier by comparison. Sorry...

Here is a view on Earth’s moon in a region called Sinus Iridum (Bay of Rainbows), there are two capes, or points, named Promontorium Laplace and Promontorium Heraclides. This area has also been called the “jeweled scimitar” because of its resemblance to the scimitar sword (or sabre). If you look close, you can see some “wrinkle ridges” on the flat surface area. These were caused when lava cooled and contracted, they are also referred to as veins.

Sky-Watcher Star Adventurer mount (it has a lunar tracking mode available) + Sky-Watcher Evostar 72ED (72/420mm) + filter wheel with Baader LRGB filters set (for the transit UV/IR filter was used) + Barlow 2x + ZWO ASI174MM camera. To get the color shot R, G and B channels, 3000 frames per each (and 3000 more through UV/IR filter, which was used as L channel later on). As the Moon doesn't fit the field in this configuration, two panels were shot. ISS cropped out manually using Gimp; stacked and sharpened using cvAstroAlign (25 frames out of 70 went into stack); later on got ISS out using Gimp. Moon stacked using AutoStakkert! 3, then aligned the channels using PlanetarySystemLRGBAligner, then combined to obtain RGB using ImageMagick; L channel added in Gimp. Then assembled the panorama using Hugin. Post-processing in RawTherapee. Added ISS back using Gimp (excluded 37 out of 75 frames)
This is with my home setup -- Celestron Edge HD 925 with ZWO ASI120MM camera, 3x Barlow, and Optolong RGB filters. I wanted to see if I could keep Europa and its shadow looking decent while shooting with a mono camera. To do this, I limited the RGB SER files to 12 seconds and took each set in under a minute. After stacking in AutoStakkert and doing some sharpening in PixInsight, I used WinJUPOS to derotate the frames so I could check the resulting RGB images for color distortions around the moon or its shadow. Seeing that they weren't discernible, I stacked and derotated four RGB images from 0527 to 0531 UT in WinJUPOS and tweaked the result a little in PixInsight and Photoshop.
Europa is visible just below and a bit to the right of its shadow. Even though the seeing was better at this time compared to my previous image (see flic.kr/p/2pfGTKC ), I still couldn't get any detail on it. This is from my backyard in Long Beach, CA.
Rupes Recta, the "Straight Wall", is the vertical bright line bisecting the eastern Mare Nubium. It is a fault line that is 110 km long, 250 meters high, and 2.5 km wide with a 7-degree slope. The prominent crater at the top left corner is Arzachel and at the lower corner is Purbach. (A. Ruki 54, 55)

There is a conspicuous chain of large craters which lines up along the same meridian on the Southeastern limb of the Moon, as seen here. They start on the southeastern shore of the Sea of Fertility and continue south (to the right in this image). The chain consists of, from left to right, Langrenus, Vendelinus, Petavius, and Furnerius. The craters formed at different times, separated by gulfs of millions, even billions of years.
• Langrenus & Vendelinus: These craters are the first two links of the Great Eastern Chain. Langrenus and Vendelinus are two large 90-mi. craters located on the southeast shore of the Sea of Fertility. One is considerably older than the other. It should be easy for you to decide which that is. If you cannot tell, take note of the terraced walls and central peaks of Langrenus, standing out with clear detail. Note also the pattern of craterlets that radiate away from Langrenus. These are features of younger craters. Vendelinus, in contrast, has a smooth floor, where lava and rubble from later impacts filled its basin. The central peaks have been buried by this debris. The rim of Vendelinus is overlain by younger craters, and its surrounding rampart is battered down. These are the signs of great age. Indeed, these two craters may differ in age by a billion to as much as 3 billion years.
• Petavius: This is an example of a floor-fractured crater, a type of crater that has been modified by later volcanism, uplift, and consequent fracturing. The floor of Petavius is nearly 1,000 feet higher near its center than around the edge! Turbulence and volcanic upheaval from below split the central mountain (which rises to nearly one mile above the floor) and formed the rilles. The principal rille, Rima Petavius, is quite prominent: it extends from the central peak to the southwest wall. Petavius falls between Langrenus and Vendelinus in age. While it retains a notable central peak and its walls are terraced, its walls are also slumped and battered by secondary craters.
• Furnerius: This is the southernmost of the craters that make up the Great Eastern Chain and it is very old, perhaps as old as Vendelinus. The walls have been battered down, and there are several craterlets of varying sizes on the floor, which also shows no central peak and some backfilling by lava and rubble.
The imaging system used was a Celestron EdgeHD SCT, 8" aperture, f/10, 2032mm on a Celestron Advanced VX mount. I used a ZWO ASI290MM camera. I collected 4000+ video frames, then stacked 10 percent of them into a single image using AutoStakkert! 3. I applied some mild wavelets processing with Registax 6 and a final buff in Photoshop.
I want to acknowledge the work of Andrew Planck and his wonderful blog posts which first directed my attention to this (and many other) fascinating lunar features. I borrowed his organization and blended some of his text with my own for this post.

My astro rig is not particularly well suited for an event like this, but it made for an entertaining evening.
The Mars images were spaced by about 5 minutes. The final moon image was output from Autostakkert -- the best 50% of 217 pics.

Jupiter and Ganymede, photographed from my backyard in Long Beach, CA
Autostakkert did a better job of tracking Ganymede when it was closer to the disk of Jupiter. I was able to get some surface detail on the Galilean moon in this image.
30 s SER files were taken with a ZWO ASI120MM camera through Optolong CCD RGB filters on a Celestron Edge HD 925 telescope using FireCapture. The top 75% of frames went into 7 stacks of each color filter. These stacks were made in AutoStakkert, then sharpened in PixInsight. Stacks were combined and derotated in WinJUPOS, and the resulting R, G, and B images were combined in WinJUPOS to make a de-rotated single color image. Color balancing in Registax, then final touches in Photoshop.
Autostakkert didn't seem to pick up Ganymede in these images, thus rendering it featureless.

In this photo I attempted to isolate four lunar craters that lie close to the southwestern limb of the Moon. This position makes it difficult to see them from an Earthly perspective, as we see them greatly foreshortened. They are imaged here soon after sunlight first shines into their exteriors. Areas of the Moon to their west are still hidden in the shadows of the two week lunar night. Only a few high points of these features are illuminated. The low angle sunlight emphasizes the relief of the lunar landscape, and heightens the three-dimensional structure of our planet's partner.
The largest crater is Schickard. This crater is among the largest lunar craters that we can see from Earth. It is a circular basin of 227 km diameter. Close examination shows that it has a two-toned floor. This effect has been explained as follows: the light material was blasted out by the gargantuan impact that formed a ringed basin beyond the bounds of this image. That material was partially covered some time later by darker lava that erupted onto the floor in the north and the southwest. This difference in shading is more striking as it is more directly illuminated.
Below Schickard lies a trio of adjoining craters. Two I will mention in passing. The largest is Phocylides, roughly half the diameter of Schickard, and having a depth of 2.1 km. The northern rim of Phocylides overlaps the much smaller Nasmyth crater. Nasmyth crater is only 1.4 km deep, so the two craters appear to rise like steps out from the Moon. This step-like effect continues with the third crater of the trio, Wargentin. Not only does the floor of Wargentin lie higher than its two close neighbors, the floor of Wargentin is actually higher than the surrounding lunar surface. Wargentin is one of a very small number of craters that have this characteristic. The explanation is fascinating. While many lunar craters have had their floors flooded by lava that has upwelled from the lunar interior, in Wargentin's case this flooding continued to the point that it overtopped portions of Wargentin's western rim, perhaps spilling over and out across the regions to the west. That would have been an incredible sight. Streams of lava many kilometers across might be seen cascading over the crater's rim and down a thousand or more feet to the plains below. From inside, Wargentin might look like a lava infinity pool 84 km wide!
Instrumentation:
Celestron EdgeHD 8 telescope, ZWO ASI290MM monochrome camera, Celestron Advanced VX mount.
Processing:
Video data captured with Firecapture software as a 60-sec .ser file. Pre-processing of the .ser file with PIPP. Best 10% of 4919 video frames were stacked with AutoStakkert!3, wavelets processing done with Registax 6, and final processing in Photoshop CC 2020.
This is from a series of 19 SER files recorded with a ZWO ASI224MC camera in conjunction with a 2x Barlow, ZWO ADC, and ZWO IR cut filter. This was with the Celestron C14 at Cerritos College. Data was taken between 0852 and 0911 UT, with stacking in AutoStakkert, sharpening in PixInsight, combination of derotated images in WinJUPOS, then final touches in PixInsight and Photoshop.
