The Partial Solar Eclipse of June 2021 as seen from Milan, Italy at 12:46 local time. Here I have used a Daystar Quark H-Alpha filter to show the Chromosphere along with a nice prominence on the east limb of the Sun. The black portion of the Moon disk on the left is of course a simulated continuation of the main part which is actually eclipsing the Sun's surface.

This photo shows areas of the Moon targeted by Apollo Missions, including most of Mare Cognitum and the Fra Mauro Formation, as well as northern portions of Mare Nubium. It lies south of my previously posted photo of Copernicus Crater, connecting with that previous image in the region around Reinhold crater, seen here in the extreme upper left corner. It also joins nicely with a yet-to-be-posted image covering more of Mare Nubium 😊.
I have wanted to image more of the Apollo landing sites, and these are two that I have hitherto missed. Let’s start with Apollo 12. The Apollo 12 landing site, marked here with a red plus sign, was selected as a priority landing site by NASA in large part for the opportunity it presented for demonstrating the ability to land precisely at a chosen location. The target for Apollo 12 was the site where the Surveyor 3 spacecraft landed, in the northern part of Mare Cognitum. Commander Pete Conrad, Jr. brought the lander down 600 feet from Surveyor 3, closer than planned, close enough that the lander’s exhaust blasted the Surveyor 3 craft, cleaning portions it of a layer of accumulated dust. This success marks the only time that humans have visited the site of a previous landing on another heavenly body. It cleared the Apollo program for a series of targeted landings in difficult landing areas having scientific significance. Apollo 12 found the rocks at its site differed chemically from those found at the Apollo 11 site, showing that different geological processes shaped the history of the two regions. Further, as the Apollo 12 site lies within a ray of material ejected from Copernicus Crater, it was possible to learn some things of the geological history of Copernicus, including its possible 800 million year age (although this is still a matter of dispute). This site also saw the first installation of a science package designed to measure lunar seismicity, solar wind, lunar magnetism, and other subjects. These instrument packages, installed by each subsequent Apollo Landing Mission, provided data until 1977.
Incidentally, Mare Cognitum was officially named as a distinct area within Mare Procellarum in 1964. This was when NASA was planning the successful impact probe mission, Ranger 7, the first American spacecraft to return closeup images of the Moon's surface. The name, “Mare Cognitum”, means “the Sea that has Become Known”. Apollo 12 landed in a northern portion of Mare Cognitum. The circular basin below the Apollo 12 site and filling the left center of this photo is also part of Mare Cognitum. Ranger 7 crashed into the eastern side of this circular part of Mare Cognitum on July 31, 1964.
The green plus sign in upper center marks the landing site of Apollo 14. The hilly region which surrounds the site is known as the Fra Mauro Region. Fra Mauro Crater is the large circular basin immediately below and right of the marked landing site. A crack, or rima, cuts across its floor. It abuts two smaller craters, Bonpland on the left and Parry on the right. Together, the three craters form an upside-down Micky Mouse shape that is a convenient visual landmark when viewing the Moon.
This area was selected for an Apollo landing because it was thought to be formed of ejecta from the Mare Imbrium impact event, and thus a source for evidence that could help unravel the geologic history of the moon. In fact, this evidence it was considered so important that it had been assigned to the Apollo 13 mission; when the Apollo 13 landing was aborted, Apollo 14 was retasked to this mission. The material that comprises Fra Mauro Region was known to be widely distributed across the nearside of the Moon, so it serves as a convenient stratigraphic marker, dividing features that are older than the Imbrium impact from those that are younger. By returning samples of the Fra Mauro Formation for study on Earth, a precise age could be assigned to this geologic transition. Age-dating the samples in terrestrial laboratories indicated that the Imbrium basin formed approximately 3.85 billion years ago. Nearly all of the Apollo 14 samples are breccias, rocks formed from pieces of other rocks, often held together by an impact-melt matrix. Surprisingly, one rock was found that almost certainly originated here on Earth, with composition and chemistry that is unlike those of lunar materials. It probably arrived on the Moon as a meteorite, blasted away from the Earth in some long-ago meteor impact to the Earth. Similar bits of Earth may be scattered across the lunar landscape.
Two final comments. At the bottom center of the photo, amidst the lava plains of Mare Nubium (“Sea of Clouds”) is a very distinct crater. This is Bullialdus. Bullialdus is a lunar impact crater located in the western part of the Mare Nubium. The relatively isolated location of this crater serves to highlight its well-formed shape. Bullialdus has a high outer rim that is circular. The inner walls are terraced and contain many signs of landslips. The outer ramparts are covered in a wide ejecta blanket that highlights a radial pattern of low ridges and valleys.In the center of the crater is a formation of several peaks and rises that climb to over a kilometer in height.
The name of Mare Nubium, derives from early telescopic observations. The mare’s numerous ghost features, and various higher-albedo crater ejecta criss-crossing the basin, conjured up the idea of lunar clouds. Scan the area around Bullialdus and note how many partially flooded, or “ghost” craters can be seen. Bullialdus is clearly different from its neighbors.

The telescope was on an EQ5 Pro mount on a permanent pier, tracking at lunar rate. It was still twilight when I started imaging and I was also dealing with varying amounts of thin cloud. The Moon was 85% Waxing Gibbous. Schiller is on the few genuinely oval shaped lunar craters. Most of the others that appear oval are only that shape because of its position as viewed from Earth, i.e. the crater is foreshortened when located towards the edges so it causes the crater to look slightly squashed.

I received a flattener for the 115 the other day which gave me the spacing needed to reach focus and get a image! Although this is the first image taken through the 115 i dont consider it its true first light, a DSO is needed for that.
I am happy with the image, after imaging the Moon with a 200mm lens all this time, having the frac with a focal length of 805 makes a big difference. I shot 88 single images and stacked the best 50% in Autostakkert!2 then used wavelets in Regitax 5. I tried not to go overboard on them which is easly done.
Next time i think i will take a video to stack, will be interesting to see what produces the best results.

Transit of the moon Ganymede (largest moon in the Solar System) over Jupiter, with a projection of its shadow on the planet. In the images, the moon Ganymede is the spherical (grey hued) object seen in the vicinity of the Great Red Spot. Ganymede's shadow projection appears as a dark circle near the center of Jupiter.
"Fifth in line from the Sun, Jupiter is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined. Jupiter's familiar stripes and swirls are actually cold, windy clouds of ammonia and water, floating in an atmosphere of hydrogen and helium. Jupiter’s iconic Great Red Spot is a giant storm bigger than Earth that has raged for hundreds of years".

Captured with a Nikon D5500 and a 10-inch Meade LX200 'Classic' f/6.3 wide-field telescope.
EXIF data is removed via stacking processes in Autostakkert!2 for planetary imaging and in Deep Sky Stacker for deep sky imaging.
Jupiter, the largest planet in the Solar System, almost 2 months after its 2023 opposition. The Great Red Spot (GRS) is visible near the center. This is the largest storm in the Solar System, although it has been shrinking in recent history. Even in its "smaller" state, the GRS is still roughly the size of Earth.
Jupiter rotates about its axis every 10 hours, making it the fastest-rotating planet in the Solar System. As a result, it is noticeably wider at the equator. Its atmosphere is separated into several bands at different latitudes, which creates turbulence and storms along the boundaries.
I'm finally making some progress on these images. This was a surprisingly good result from late in the 2023 Jupiter season. I'm excited to process the remaining images in the archive!

The Shadow of Io and the Great Red Spot
I used the 2700mm f15 Skymax 180 scope for this shot but doubled its focal length to 5400mm with a 2x Powermate.
Prior to my session, I used Stellarium to look for interesting interactions between Jupiter and its moons and finally found what I was looking for. Io was to sit just outside Jupiter’s disk on November 15th, with its dark shadow projected onto the planet’s surface and the Great Red Spot front and center. The principles were projected to be in position by 11pm. It took nearly two hours to get the scope set up and cooled down but I still had plenty of time before the big event.
I used the ZWO 585, making SER files in FireCapture at about 14fps, stacked 1,588 individual frames in Autostakkert, sharpened with Registax and tweaked in Lightroom.

Fresh off the sensor, here is tonights 58% moon with full colour and earthshine as imaged from Byron Bay Observatory. When the moon gets this bright and high in the sky she is hard to ignore, and it’s almost impossible to image anything else except the larger planets. So I’ve tried here to photograph her as best as I can with everything I’ve learned. The 50+ exposures took about 15 minutes but the processing took me a over an hour.
The colour is natural and real, the moon has hues that relate to its geology – blue for titanium oxide and green for lithium. The blue on the dark side however is coloured by the earths reflection, and being mostly water on the surface, we are a blue planet and our blue light is reflected back to the moon. The clear conditions and Byron Bay’s proximity to the equator and low light pollution mean we get some of the best views of the moon in the world.
For the technically inclined.. These RAW Canon DSLR images are too big for Autostakkert so I used Nebulosity for stacking, aligning on points of light near the terminator, and then PixInsight for deconvolution and colour saturation. I exposed the bright and the dark side of the moon separately then layered them in Photoshop with a warped layer mask gradient to preserve the curvature between them.
