As observed from Washington DC on 11/4/2025 at about 9:00 pm ET, a full Beaver Supermoon image was obtained by stacking 10 minutes of AVI (i.e. RAW) video. The video was taken with a Seestar S50 telescope. Once the video was captured the telescope played no further role in the processing as set forth below.
The stacking of the RAW AVI frames was done with AutoStakkert! 4.0.11 (hereafter AS). The AS workflow is: (1) Open and go to Image stabilization and Quality estimator where various options are chosen; (2) Analyse and go to Reference frame, Stack options and Super resolution where appropriate options are chosen; (3) Stack.
For Image stabilization, the parameters used were Surface, Improved tracking and Crop. For Quality estimator, Automatic was selected. For Reference frame, Double stack reference was used. After initiating Analyse the top 58% in quality of the frames was selected for stacking. Next, various choices of alignment point size and brightness were evaluated to determine which combination gave an optimal coverage of alignment points on the reference lunar frame surface. The choices made here would ultimately impact on the quality of the stacked output. In the present case, alignment point size and brightness were chosen to be 144 and 50, respectively, which resulted in 113 alignment points which fully covered the lunar surface. Lastly, after checking Replace and Multi-scale options, the chosen percentage of frames was stacked to get a TIF output image.
The TIF output image was cropped to a square aspect in Lightroom Classic. After masking, the highlights and shadows in the background sky were reduced by setting the respective sliders to -50 each. For the lunar subject, a tonal adjustment was made by setting the sliders for exposure, highlights, whites and blacks to 0.15, 8, 16 and -12, respectively; a color adjustment was made by moving the temperature and tint sliders to -20 and -19, respectively; and lastly effects were introduced by sliding the clarity, dehaze and grain values to 8, 8 and 10, respectively.

Knowing seeing was dreadful I still went out to see if I could image Mars. Seeing was appalling, Mars was only at 10 degrees, the same as my winter Sun, so therefore was in the tree as well. I am amazed this came out, honestly, Mars was never a round circle so I don't know how Autostakkert made it one :)

The Moon. This shot was taken on the night of 7-1-20. I don't normally do Moon or planet imaging, but I was tweaking part of my rig and the Moon as there ... so why not? I shot a 200 frame high res video sequence using my ZWO ASI294MC-Pro camera and SharpCap Pro software. When you watch the video you have see the image of the Moon wavering around as the atmosphere was distorting it. The video was analyzed and the sharpest 66 frames were stacked using Autostakkert 3 software. I then used Registax software to do Wavelet sharpening of the image. Finally, Photoshop was used to finish things up. It was interesting to try out a different form of capture and image processing.....

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".

"Posidonius"
Posidonius is located on the north-eastern edge of Mare Serenitatis, to the south of Lacus Somniorum and ominously named Lacus Mortis, which was featured in an image I posted two days ago. Posidonius is 95 km wide and 2.3 km deep. It is an impressive crater, with many distinctive features that make it fun to examine through a telescope. Here it is seen in "afternoon" lighting, with the sunlight coming in at a moderate angle from the west.
Posidonius is a textbook example of a "floor-fractured crater". Close examination will immediately reveal the reason for this designation: the floor of the crater is crisscrossed by numerous large cracks. This kind of crater is most often found in the regions of the moon near lunar mare. The mechanism of their formation involves several stages. Sometime after the impact event that gouged out the crater, lava upwelled from the lunar interior and formed a magma chamber beneath the crater. Pressure within the magma chamber then lifted the entire floor of the crater, creating a bulge. Eventually the lava found its way to the surface through cracks in the crater floor and covered it to considerable depth. As the lava cooled, it contracted, cracked, and slumped back downward into voids in the magma chamber. The cracks within the crater are known collectively as Rimae Posidonius.
Posidonius lacks a notable central peak. Instead, numerous hills are seen. One relatively unique feature is the "doubling" of the eastern rim. It appears that there might be a second crater rim, or perhaps part of the original eastern rim broke away and slumped toward the center of the crater . Posidonius also features a prominent (11 km diameter) secondary crater within it called Posidonius A.
The area to the southeast of Posidonius is quite rugged and mountainous. This is a portion of the Montes Taurus. Here too are prominent fissures. The most prominent lies to the east of Posidonius. This is Rima G.Bond. The area is riddled with a multitude of small craterlets and many old, worn craters.
In contrast, the area to the west of Posidonius seems remarkably featureless and smooth. This is Mare Serenitatis, the "Sea of Serenity". Serene indeed. A few small craters pock the surface, and long, low ridges meander across its expanse. Whatever history of intense meteor bombardment this area has received over the eons, most evidence of it was covered up by the vast lava flows that created this mare. In fact, this entire sea was created by an enormous collision of the Moon and an asteroid, which created the Serenitatis Impact Basin, one of several such basins seen on the Moon. "Serene"? Maybe not so much.

This was another tough imaging session, with the planets playing hide and seek with endless bands of cloud, rain showers and a biting wind. Thankfully we had some brief gaps to get more photos of this awesome event!
Taken by Mary and Mark McIntyre from Oxfordshire, UK with a William Optics 70mm refractor and ASI120MC on a Star Adventurer Mini. We shot as many 1,000 frame videos as we could during the gaps. The videos used to create this image were taken at 17:36 and 17:45.
All the processing on this was done by me, Mark has processed them himself as well and is posting on his own Flickr page too.
The videos were stacked using Autostakkert! 3; the first one was 50% of 1,000 frames, the second was 65% of 1,000 frames. The stacked images were then processed using Lightroom. I did a parallel process on the 17:36 video, one to brighten Saturn and the other to turn the brightness down on Jupiter to preserve the detail. The video at 17:45 had a higher exposure setting to bring out the Galilean Moons. This final image is a blend of those three different exposures to create an image with a larger dynamic range.
Given the weather forecast for tomorrow when they're even closer, I'm so pleased we were able to capture this today. This is not a big telescope so it's mind blowing that we were able to pick up so much!
Taken with a Skywatcher ED80 and a Canon 600D. 4 image stack in Autostakkert. Having colour problems when using PIPP to convert RAW images to tiffs. No issues at all when using PIPP to convert jpg's. These colour artifacts only appear during wavelet sharpening after stacking, as a result the above image is only a 4 image stack but still some red artifacts, any more than 4 I get green artifacts. JPG's are so much more reliable and faster to process and are just as detailed. Reverting back to jpg for now. NOTE :--- Later on tried converting all the RAW images to 16bit tiffs before processing with PIPP to center and crop and the colour issue disappeared but the resulting image was no better than taking jpg's straight from the camera in the first place and much less processing time too :-)

Camera/Telescope: ASI290MM + red filter, 12" f/8 GSO RC
A time-accurate composite image from 2 consecutive 30-second video captures required to create this image, over the course of approximately 1 minute. A separate acquisition for Saturn's brightness for the moon's brightness is required, as their apparent exposure requirements are very different. While it CAN be captured a single acquisition, rather, by adjusting the gamma level of the imaging camera (boosting it...), a better quality image can often be obtained by properly exposing for each target.
Post-processed using Autostakkert!3, PixInsight, and combined in Photoshop. After stacking and processing was done, the moon and Saturn were then recombined into one final image.
Using a monochrome camera, it takes time to capture different exposures. As time elapses, in the apparent close quarters where two objects are moving independently in space, they must be treated separately and recombined in post, requiring a composite image.
We all hate composite images. But, when they are created with transparency and ethics, that’s what we as astrophotographers need to do. We must remain ethical and accurate at all times.
High-resolution imagery of lunar details around five prominent craters in the Southern Highlands region.
What I want an observer to see in this image is the multitude of tiny craterlets and other small features scattered throughout the image. I have not yet measured the smallest of them, but it is likely that they range down in size to less than 2 km diameter.
I have never achieved this kind of detail in my imaging before. I am trying to find ways to best display these features without overprocessing the data. Anyone with advice, please comment or send a flickrmail.
