What set this one off, was a few high clouds traipsing by.
This new image from ESA’s Mars Express shows the distinctive and fascinating Mawrth Vallis, one of the most promising locations on Mars in our search for signs of life.
The region is thickly coated in light-toned clays containing silicate minerals; these deposits – some 200 m deep in places – are the most widespread found on Mars, and are obviously visible in these new images. The light clays are overlaid by darker ‘caps’, which can also be clearly seen and are thought to be of volcanic origin. The silicates within these clays are evidence that the surface has been altered by water, hinting at a habitable environment in the past.
The clays are annotated here for clarity, alongside many other fascinating features: craters, highlands, dark volcanic rock units, crater walls and ejecta, lowlands, knobs and mesas.
This image was created from data collected by the Mars Express High Resolution Stereo Camera (HRSC) on 18 February 2023 during orbit 24164. North is to the right, the ground resolution is approximately 18 m/pixel, and the image is centred at about 25°N/339°E.

North is up. This image is derived from a single RGB run captured in Firecapture, stacked in Autostakkert, wavelet sharpened in Registax, and color channel derotated in WINJUPOS.
Seeing was Average at capture. I had hoped to stack and sharpen in PSS, but the result was disappointing. I have four more RGB captures that can be derotated and added to this data. I feel like I am missing something with PSS, which is still new to me. I'll take a deeper dive when time permits.

This image, based on observations from NASA’s Dawn spacecraft, shows the largest mountain on the dwarf planet Ceres.
Dawn was the first mission to orbit an object in the asteroid belt between Mars and Jupiter, and spent time at both large asteroid Vesta and dwarf planet Ceres. Ceres is one of just five recognised dwarf planets in the Solar System (Pluto being another). Dawn entered orbit around this rocky world on 6 March 2015, and studied its icy, cratered, uneven surface until it ran out of fuel in October of 2018.
One of the features spotted by the mission is shown here in this reconstructed perspective view: a mountain named Ahuna Mons. This mountain rises to an elevation of 4000 m at its peak – Europe’s Mont Blanc on Earth would rise slightly above it (as measured from sea level) – and is marked by numerous bright streaks that run down its flanks. Scientists have determined that these marks are actually salt deposits left behind from the formation of Ahuna Mons, when plumes of saltwater and mud rose and erupted from within Ceres, puncturing the surface and creating the mountain seen here. While temperatures on Ceres are far colder than those on Earth, this mechanism is thought to be somewhat similar to the formation of volcanoes by terrestrial magma plumes.
More recently, a study of Dawn data led by ESA research fellow Ottaviano Ruesch and Antonio Genova (Sapienza Università di Roma), published in Nature Geoscience in June, suggests that a briny, muddy ‘slurry’ exists below Ceres’ surface, surging upwards towards and through the crust to create Ahuna Mons. Another recent study, led by Javier Ruiz of Universidad Complutense de Madrid and published in Nature Astronomy in July, also indicates that the dwarf planet has a surprisingly dynamic geology.
Ceres was also the focus of an earlier study by ESA’s Herschel space observatory, which detected water vapour around the dwarf planet. Published in Nature in 2014, the result provided a strong indication that Ceres has ice on or near its surface. Dawn confirmed Ceres’ icy crust via direct observation in 2016, however, the contribution of the ice deposits to Ceres’ exosphere turned out to be much lower than that inferred from the Herschel observations.
The perspective view depicted in this image uses enhanced-colour combined images taken using blue (440 nm), green (750 nm), and infrared (960 nm) filters, with a resolution of 35 m/pixel. Ahuna Mons’ elevation has been exaggerated by a factor of two. The width of the dome is approximately 20 km. The spacecraft’s Framing Camera took the images from Dawn’s low-altitude mapping orbit from an altitude of 385 km in August 2016.

Last night's 'Wolf Moon', captured before the mist and cloud inevitably rolled in.This image is the result of stacking the best 50% of 250 frames, captured using a ZWO ASI071 Pro camera with an Altair Astro quad-band filter, attached to an Altair Wave 115ED camera. The frames were graded and stacked using Autostakkert2, then processed using Registax6 and Photoshop CC.
Comet C/2023 P1 (Nishimura) September 3, 2023. This comet is bright enough to photograph with a small telescope and should be visible in binoculars (I didn't try until the sky was too bright so didn't see it), but not naked eye. The nice, long, straight tail stretches nearly to the corner of this frame.

Comet 67P/Churyumov-Gerasimenko passes through the constellation Gemini on three consecutive nights: November 6, 7, and 8, 2021 (right to left), near the closest it will come to the Earth in its orbit. This is the brightest comet in the sky right now, though still not really very bright at all. ESA's Rosetta spacecraft orbited Comet 67P and the Phillae probe landed on it back in 2014. The orange-ish star at upper right is upsilon Geminorum, one of the bright stars in Gemini.
This is a composite of multiple exposures taken over several hours on each of the three nights. These were combined to produce a panoramic view of the background and of the comet on each night.

A spectacular double crater dominates this scene on Mars, pictured by the CaSSIS camera on the ESA-Roscosmos ExoMars Trace Gas Orbiter on 7 June 2021.
The crater duo is located in an otherwise smooth plain of Arcadia Planitia [39.1°N/174.8°E].
Double craters like these are formed when two meteorites impact the surface simultaneously and in very close proximity. The two impactors would have originated from the same object that broke apart when it entered the martian atmosphere. The two craters are of similar size, which means that the two projectiles were approximately the same size as well.
During the impact, the interaction of the two shockwaves created an ejecta blanket with a butterfly shape. The remarkable linear streaks in the ejecta material radiates around the double crater, and are an indicator of the good level of preservation of this feature.
To the north are large isolated hills that likely predate the formation of the double crater.
TGO arrived at Mars in 2016 and began its full science mission in 2018. The spacecraft is not only returning spectacular images, but also providing the best ever inventory of the planet’s atmospheric gases, and mapping the planet’s surface for water-rich locations. It will also provide data relay services for the second ExoMars mission comprising the Rosalind Franklin rover and Kazachok platform, when it arrives on Mars in 2023.

On July 14, New Horizons mission scientists will soon obtain the first images of the night region of Pluto, using only the light from Charon, itself softly illuminated by a Sun 1,000 times dimmer than it is at Earth.
This image looks almost decent, but there are some issues that I want to work on. As for softness, I am well-collimated and I prefocused on Alderaban, but average seeing could be an issue. I can add an IR/UV cut filter. I noticed an image size issue in WINJUPOS when making the measurements in the wire frame. It seems that IR, which I used for the R channel, is much less intense than the G or B channels. Because of this the IR image appeared somewhat smaller than the G or B channel images. I am going to go back to using the Red filter for the R channel.

A change of tactics for my latest image of Saturn. Rather than using my usual colour camera, I used a mono camera and filter wheel to capture each of the colour channels separately. While this is a little more time consuming, and I still have a lot I could improve on, I think the results are already noticeably better than my previous attempts.
This image was captured using a Sky-Watcher SkyMax 180 Pro telescope and an Altair GPCam 290M mono camera with a ZWO Mini Electronic Filter Wheel and Astronomik Filters (Luminance, Red, Green and Blue). It is the result of 3000 frames for each channel, captured using Firecapture. Each channel was separately stacked in AutoStakkert2 and pre-processed using Registax 6. The channels were then aligned using WinJUPOS before being combined and processed using PhotoShop CC.
Something a little different today! This is a composite image of the sun, showing the surface detail and prominences, while being photobombed by a passing plane.
The image was taken using an Altair GPCAM 290M with a 0.5x focal reducer, attached to a Lunt LS50Tha 600B PT solar scope. The image was captured using SharpCap Pro, pre-processed using AutoStakkert2 and Registax6, with final processing done using Photoshop CC.
Not great seeing, but it is Saturn season. Mewlon 210 with QHY video camera. 500 frames stacked with RegiStax, denoised with Luminar AI.
Comet Leonard (more formally known as C/2021 A1) is brightening, still not up to naked-eye visibility though unless your eyes are a lot better than mine; may be possible in binoculars. This image was made this morning before sunrise from fairly bright suburban Bloomington, Indiana (plenty of light pollution and a last quarter Moon) the tail is visible in the image for about 1 degree (about twice the Moon's diameter) and the green coma is very obvious.
84 frames, each 90 sec. (just over 2 hours total exposure), processed in Astro Pixel Processor, once to register on the comet, again to register on the stars, processed in Lightroom and composited in Photoshop.
