I think the universe is pure geometry - basically, a beautiful shape twisting around and dancing over space-time.

This image, captured on 25 March 2020, shows the bottom of the 400 km in diameter Antoniadi impact crater, which is located in the northern hemisphere of Mars in the Syrtis Major Planum region. The blue colour of the image, centred at 21.0°N, 61.2°E, does not represent the real colour of the crater floor but highlights the diversity of the rock composition inside the impact crater.
In the centre of the image are dendritic structures which look like the veins on oak leaves. These structures, evidence of ancient river networks in this region, protrude from the surface, unlike channels, which are usually sunken in the surface. This is because the channels were filled with harder material – possibly lava – and over time the softer rocks surrounding these branching channels have been eroded, leaving an inverted imprint of this ancient river system.

A ten-exposure HDR composite of tonight's waxing crescent moon, captured and processed identically to earlier HDR composites of the moon.
What set this one off, was a few high clouds traipsing by.

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.

The exhibition will offer visitors the chance to explore the solar system in an innovative presentation where sizes and location of the various planets will appear to be real.....
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.

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.
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.

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.
