Broadstairs, January 2022.
This from 6 45 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 26% of 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.
Acidalia Planitia and Chryse Planitia are visible on the left side of the northern hemisphere below the north polar cap. There appears to be some weather just south of the polar cap toward the limb of the planet.

Jupiter and Callisto, photographed from Long Beach, CA
Callisto is Jupiter's second largest satellite and the third largest moon in the solar system. It has a low albedo due to having an ancient surface, so I boosted its brightness a little here so it could be seen more easily.
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 48% of frames went into 14 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.

"Tycho's Craterlets"
Last night a friend posted a shot of the gorgeous ray system of Tycho. It reminded me of this image that I had forgotten about in my image drive. This shot illustrates another aspect of ray systems, the myriad secondary impact craters created when ejected material falls back to the Moon.
Rays are created when a large meteor or an asteroid hits the Moon. The meteor or asteroid usually does so at tens of thousands of miles per hour. They scatter surface material at high speed when they hit, then they penetrate deep below the surface. Their kinetic energy is converted to heat, which vaporizes the meteor/asteroid and much of the moon-stuff around them. That all expands in a catastrophic blast upward and outward from the impact point. The material blown outward is everything from county-sized chunks, to glassy dust, to incandescent gas. The gas may escape the Moon altogether, or cool and condense on the Moon’s surface. The dust blows outward in streaks across the face of the moon, sometimes for thousands of miles, creating the rays my friend captured. The chunks usually fall back onto the moon, blasting craters of their own, or they may scour the surface, cutting radial valleys through mountains and leaving scars as they skip over the surface. That is a sequence of events you do not want to witness up close.
This picture is my best effort to show the effects of those big chunks that fall back onto the moon. Tycho crater is a young crater, so these effects are more clearly seen in its case. Tycho is the crater above center and a little right, the one with a brightly-lit western interior rim, a deeply shadowed eastern floor and a brightly illuminated central peak. Once you find it, look at the craters to the east (right) of Tycho. Look at their insides. Their floors are riddled with tiny craters. Some are arranged in lines stretching away from Tycho, like the rays. My photograph can resolve craterlets down to a little under two kilometers wide. There are hundreds, maybe thousands of them visible in this image. They are most densely packed near Tycho, but they can be spotted all the way to the right edge of the frame. For every one visible here there are many smaller ones below resolution. They have to await a bigger ‘scope.
I used an 8" aperture, 2032 mm focal length f/10 telescope as my lens (Celestron EdgeHD8). A monochrome planetary video camera (ZWO ASI 290MM) was used to collect 2086 video frames at 69 frames per second. This camera has a tiny sensor, with a crop factor of 6.7, so it can only see a tiny part of the Moon.
Of those 2086 video frames, the best 25% (522) were stacked into a single image. This procedure, called "Lucky Imaging" maximizes image sharpness and minimizes image noise and atmospheric blurring. AutoStakkert!3 software did the actual stacking.
The stacked image received wavelets processing in Registax 6 to help pull details from the remaining image noise.
Final processing was completed with Photoshop CC2020.

This photo spans an area from Mare Cognitum (in the upper left) to the Southern Highlands (in the lower right) along the lunar terminator. It includes much of Mare Nubium and the show-stopping beauty of Bullialdus Crater.
I often find themes for my discussions of my moon photos. For this one, I choose three: “Contrast”, “Deep Time”, and “Treasure Hunt”.
The simplest of these is Contrast. There are many examples of contrast here. What examples do you see? Of course, there is a broad range of brightness across the image, with deep darks in the lower left, brighter gray tones in the upper right, and near whites on high points that catch the rising sunlight most directly. Along the day-night terminator the lightest and darkest tones are closest together, where they emphasize the ruggedness of the terrain. The contrast between the overlapping craters of the Southern Highlands and the plains of Mare Nubium is also compelling. And then there is the contrast in the age of the craters. Most of the craters here are incredibly old – worn and flooded, many buried altogether. Bullialdus stands out as strikingly different. How so?
In Bullialdus Crater, we see a classic example of an Eratosthenian Period crater. What does that mean? To address that, we come to the second and most profound theme for this image, “Deep Time”. At first glance, Eratosthenian Period craters appear relatively young. Like Bullialdus, their crater walls are terraced and sharply defined, with some evidence of slumping. The central peaks are evident and stand tall above the crater floor. The outer walls or ramparts appear thick. They rise high above the surrounding terrain. Closer examination of the outer walls shows them to bear evidence of materials that flowed outward from the crater, burying the original terrain in radially spreading hills and hummocks. Chains of craterlets dot the area, also in a radial pattern of dispersion, where larger chunks of ejected material created new craters upon re-impacting the Moon. So, what then separates Eratosthenian Period craters from even younger craters such as Copernicus or Tycho? First and most evidently, systems of rays. Younger, Copernican Period craters sit at the centers of bright, light-colored systems of ejecta rays. Eratosthenian Period craters pretty much have none. Rays are made of light-colored material dug from deep below the lunar surface and sprayed across hundreds, even thousands of miles of the Moon’s face. Over time, this material darkens to match the rest of the lunar surface, a consequence of hundreds of millions to billions of years of weathering due to solar radiation and micrometeorite bombardment. A second differentiator between Eratosthenian Period craters and younger craters is secondary cratering. Younger craters have (as yet) been spared disfiguration by more recent impacts. Here, the wonderful outer rampart of Bullialdus is marred at the four o’clock position by a younger crater, Bullialdus A. It takes a great deal of time before another large impactor to draws a bead on the area occupied by a previously gouged crater. Given enough time, it happens. Bullialdus has been around long enough to have suffered that fate.
There is no way to escape consideration of “deep time” when contemplating the Moon. Eratosthenian Period craters like Bullialdus look youngish, like middle-aged features, ones that are “mature” but “still in their prime”. On the Moon those terms describe craters that formed between 1.1 and 3.4 billion years ago. That’s a long time ago. On Earth, the Eratosthenenian Period corresponds to an era beginning when single-cellular lifeforms were dominant, extending through the emergence of photosysnthesis and later sexual reproduction, and ending with the proliferation of multicellular organisms. Take a minute and let that sink in.
Enough navel-gazing. Let’s turn to other things in this photo that I find kind of cool. To the right of Bullialdus lies an oddly shaped, non-round crater. It’s a compound crater that looks somewhat like a heart. This is Wolf Crater. In certain lighting conditions, the heart shape is pronounced, and it draws the eye. Below Bullialdus, just right of center is a round crater with a lava filled basin, no central peak, low walls that barely rise above the terrain of Mare Nubium, and an unusual teardrop southward extension. This is an old crater. It looks to me like a keyhole, which is a useful mnemonic for its name: Kies Crater. Kies Crater is also old. It clearly predates the formation of Mare Nubium, for it is all but buried by the lava flood that filled the basins of Mare Nubium. A look around Mare Nubium reveals a great many craters that have suffered such inundation. To the left of the teardrop feature of Kies a smallish mound is visible, due to the low angle light. This is a landmark named Kies Pi. It is not conspicuous, but it merits a close look. You might spot a small crater or depression on its peak. If you spot it, congratulations! You are looking down the throat of a lunar volcano. The ‘crater’ on top is a volcanic caldera. I speak often of lunar lava flows; here is one of the contributory sources for the lava that flooded this part of the Moon. Below Kies Crater and Kies Pi volcano we come to a line of cliffs and ridges that mark the boundary of Mare Nubium. These cliffs, known as Rupes Mercator, are punctuated by a pair of similarly sized and shadow-bound craters: Mercator on the right, and Campanus on the left. As Mercator lies closer to the rising sun, a portion of its floor is illuminated, and contrasts with the remaining shadows cast by the crater’s eastern rim. Below the ridges of Rupes Mercator and these two craters like another small region of mare material. This is no major feature, but it may have found its time: this is Palus Epidemiarum, the “Marsh of Epidemics”. Who calls things that?!?!
By now you probably have noticed the long crack that runs across Palus Epidemiarum, Rupes Mercator and Mare Nubium, from the terminator in lower center and extending to the middle right margin of this photo. That crack is Rima Hesiodus. At the right edge of the image, Rima Hesiodus tangentially connects to the rim of the crater for which it is named, Hesiodus Crater. If you find that, note the small crater that lies on the lower edge of Hesiodus. You might see that this crater has another crater rim concentric to its main rim. This crater, Hesiodus A is famous for being one of a small set of craters that look like bullseyes, perfect double-tap impacts drilled into the Moon’s face. Again, the deep time issue rears up. How long would you have to wait for something like that to occur at random!
OK. Enough. I mean really this time. I will close with some puzzles for the interested. This is a region blessed with a great many features that have interested Selenophiles. I will draw attention to one: the Bullialdus Causeway. I learned of it in Andrew Planck’s blog. Its nature remains a mystery, but the Causeway is visible in this image. The following links will point the curious to this and many other features of this part of the Moon. Most are visible in this image, but some, alas are not. Let the “Treasure Hunt” theme commence!

I over exposed the photos so the area which suffers from the "spotlight" effect you usually get with this telescope has completely blown out, leaving most of the disc featureless. Howerver, I was lucky enough that the only active region currently visible was just outside the area that I over exposed and these 2 huge prominences came out ok

Jupiter, photographed from Long Beach, CA
By the time I shot this, Jupiter was lower in the sky and also above my house. Both of these would degrade the seeing compared to images I got earlier this year. Right now, you have to get to work shortly after sunset to get good shots of the big planet.
There's also a bit less data here. 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 70% of frames went into 4 stacks of red images and 5 stacks each of green and blue. 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 and Topaz Labs.

The crater pair of Copernicus (center bottom) and Eratosthenes (center right) become prominent in the Moon's middle latitudes in the days following the First Quarter Moon. Here they are seen in high angle light, their floors fully or nearly fully illuminated. There is enough shadow for the multitude of secondary craterlets surrounding them to be detected. These can be seen to radiate deeply into Mare Imbrium, the broad lava plain that fills the upper third of the image.
Separating Copernicus and Mare Imbrium are the peaks of the Montes Carpatus. These mountains are remnants of the high rim of the Imbrium Impact Basin.
On the bottom left edge of the photo lies a small cup-shaped crater named Hortensius. Just above this small crater a cluster of small bumps can be seen. These low mounds are lunar volcanoes, the Hortensius Domes. Look closely and the summit calderas of some can be seen. These humble mounds are the lunar equivalent of the large shield volcanoes (e.g., Mauna Loa) seen on the Earth.

At a certain angle of the sun's illumination a number of volcanic lunar domes are visible near the craters of Hortensius, Milichius & T. Mayer. This area is also referred to by the popular name "Domeland"
A two pane mosaic obtained with my Skywatcher 254mm Newtonian, Tal 2x Barlow and a recently purchased ZWO ASI385MC.
The pane with the Hortensius Domes is a much better quality compared to my previous capture uploaded with the Copernicus crater.
4000 frames captured on each pane using Firecapture. Then approx. 1400 to 1500 frames stacked with AutoStakkert! 3.1.4.
Wavelets processed with Registax and images stitched with Image Composite Editor.
Final adjustments, collage and annotations using G.I.M.P.
Lunar south is uppermost. Best viewed in fully expanded mode.
For a reference to scale, the diameter of the crater Hortensius is 15Km (9 miles).
