🇬🇧 Illustration of the conjunction between Jupiter and the Moon. Composition of 4 photos (Full Moon of last month, Moon of tonight, Jupiter of tonight, Background taken from an archive). The Moon and Jupiter were each taken separately at the same focal length (1200mm). The size ratio between the Moon and Jupiter is therefore correct. On the other hand, Jupiter and the Moon have been brought closer together than in reality.

Copernicus is the prototype of a "young" lunar crater. It has a high rampart surrounding it, an interior that resembles a terraced amphitheater (just add stadium lights), and a system of rays that radiate away from the crater itself. It has not been battered by subsequent impacts, and it's interior still shows rubble that fell back into the crater after being blasted high above the moon's surface. All of these are textural cues that signal "freshness" in the crater marketplace.

When I captured video for this photo, atmospheric "seeing" conditions were forecast to be "average", but turned out a good bit better in the area of my neighborhood. I did not venture using a focal extender to magnify the image, but opted to use a smaller region of interest (I cropped the active area of my camera sensor to 1000x800px) on this one to close in on Copernicus.

The best 30% of 5779 video frames were used. Seeing was slightly above average, 3.5-4 on a 5-point scale.

If you've been around for about 4.6 billion years and your magnetic fields are getting a bit unstable, you may start showing spots.

Here's our Sun from 2024-03-26 with an enormous sunspot group near its equator, but that will rotate out of view in the next few days. Active region 3615 stretches nearly 250,000 km across the Sun's photosphere and has unleashed several X-class solar flares. For comparison, the average distance between the Earth and the Moon is 384,000 km -- this one sunspot group is bigger than half the distance from the Earth to the Moon! As we are nearing solar maximum for this cycle, there are many other active regions visible

This is from a stack of 9 images taken with a Nikon D5100 at a focal length of 300 mm. ISO 100, 1/80 s exposure, f/5.6 for all shots. A Thousand Oaks Optical solar filter was in place. Images were stacked in AutoStakkert, then the stack was processed in PixInsight and GIMP.

"Clavius Portrait"

I am a great fan of the lunar crater Clavius. I first noticed it in the early 1980's when I began observing the Moon through 11x80 binoculars. In those optics, it was an enormous crater that dominated landscape south of Tycho, especially on those days of the lunar cycle that it was near the terminator. I was able, with my 30 year old eyes, able to see it without binoculars at on these days. It was one of the first craters whose name I learned, after Tycho and Copernicus.

Once I began to photograph the Moon, I would be thrilled whenever my images showed Clavius clearly, clear enough to notice the beautiful arc of craterlets that adorn the Moon ' floor. The arc seems mathematically precise, and the craters seem to decrease in size with similar precision.

Over the past few years, I have tried to improve my images of Clavius. A year ago I achieved a personal milestone when I caught the region of Clavius under very good seeing conditions and with a freshly tuned-up telescope, making an image I still count as one of my best.

Here I present my current "portrait" of Clavius, this time with good seeing, a tuned telescope, AND a 3x magnifying lens. The magnification allows me to single Clavius out from the myriad craters crowding this part of the Moon. I have tried to present an image as near as possible to the visual experience one might have looking through an eyepiece. Photoshop enhancement was used, but sparingly.

The image is created from a stack of 9852 video frame images, collected in two one-minute video clips. The best 5% were identified and combined into a single image. This method, called "lucky imaging", uses each video frame as a sample of the seeing (a measure of atmospheric stability) at a brief moment in time, here averaging 1.9 milliseconds per video frame. In other words, out of 120 seconds of video, only the best 0.936 seconds were used in the final image.

So, here 'tis. My current best portrait of Clavius crater.

Tycho Crater – diameter is 86 km and it is about 4.8 km in depth, located in the southern region of the moon. The crater was named after Danish astronomer Tycho Brahe (1546–1601). From Wikipedia, “The crater is sharply defined, unlike older craters that have been degraded by subsequent impacts. The interior has a high albedo that is prominent when the Sun is overhead, and the crater is surrounded by a distinctive ray system forming long spokes that reach as long as 1,500 kilometers. Sections of these rays can be observed even when Tycho is illuminated only by earthlight. Due to its prominent rays, Tycho is mapped as part of the Copernican System.”

Il cratere Gassendi è una meraviglia lunare: con il suo imponente diametro di 110 km e il fondo segnato da intricati solchi (rimae), racconta una storia geologica complessa fatta di impatti violenti e successivi episodi di vulcanismo. Questo cratere, situato vicino al confine tra il Mare Humorum e gli altopiani, è uno dei più spettacolari per chi osserva con un telescopio. Durante le fredde notti di dicembre, il nostro satellite ci svela la sua mutevolezza, ora dopo ora, ricordandoci che siamo a solo un secondo luce da un mondo di roccia, lava solidificata e sabbia.

There is a conspicuous chain of large craters, "The Great Eastern Chain", which lines up along the same meridian on the Southeastern limb of the Moon. They start on the southeastern shore of the Sea of Fertility and continue south (to the right in this image). The chain consists of the craters Langrenus, Vendelinus, Petavius, and Furnerius. The craters formed at different times, separated by gulfs of millions, even billions of years. This photo features the trio (L-R) of Langrenus, Vendelinus, and Petavius. I captured it on the night of March 30, 2021.

• 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.

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 with an Optolong IR Pass (685nm) filter . I collected 32,399 video frames, then stacked the best 5 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.
