To my knowledge, this is the highest resolution imagery of the solar corona ever captured from Earth and the only spacecraft (Solar Orbiter) to do better works in ultraviolet from four times closer to the Sun!

HDR timelapse of partial lunar eclipse - 23/10/28
Copyright: Alberto Vacca
Description:
My aim was to represent the partial phase of the eclipse as I saw it from a binocular: the human eye has a really wide dynamic range so that the brightest and darker parts of the Moon are visible at the same time during the partial phase of the eclipse. Here is the HDR timelapse video of the eclipse:
The video is composed by 433 frames, taken every 24 seconds. The duration of the timelapse, 11 seconds, compared to the real time span of the shots, tells us that the video has been speeded up around 1000x. Every frame is an HDR union of 6 pictures taken within a wide range of different exposure times. I wrote a Python program to handle the processing of the whole sequence, taking into account the different brightness and color balance of the initial frames because of atmospheric extinction (the Moon was lower above the horizon). This way every frame has been processed in the same way with the same parameters, making it comparable with all other frames in terms of relative brightness.
The time of the shoot is: 2023 October 28, from 17:58 to 20:50 UT.
Location: Parma (Emilia Romagna, Italy), home garden.
Equipment:
- Tamron 100-400mm lens, used at 400mm
- Nikon D750 camera
- iOptron CEM40 equatorial mount
Software:
- APT (Astro Photography Tool) for acquisition
- Python program written by myself for processing

StellaNova - A Journey to the stars
This week marks International Dark Sky Week, a time to appreciate the awe-inspiring beauty and vital role of a natural night sky. Unfortunately, light pollution increasingly obscures our view of the Milky Way, countless stars, and all the wonders the universe has to offer.
As a tribute to the dark sky, I'd like to share a video I created titled 'Stellanova' that captures the breathtaking beauty of a night sky. Take a moment to step outside, look up, and marvel at the stars. Together, let's preserve our precious night sky for future generations to enjoy. Happy stargazing!

Date: Footages were shot during my travel between 2022 and 2023.
Equipments: Nikon D810, Nikkor 14-24mm
Post Processing: Raw files processed in Lightroom. Video transition and animation done in After Effects. Color correction, contrast and final adjustments done in Premiere Pro.

Aurora display on May 10/11, 2024
Auroras caused by an extreme geomagnetic storm that began on May 10, 2024 where captured with sky surveillance cameras covering visible and infrared wavelengths.
Because this forum only allows to post videos hosted on vimeo or youtube (and I do not plan to open an account there), I post preview images here.

Hello!! Thanks for add. This is my first submission. aurora borealis from the region Lorraine in France.

Aurora and Thunder
The May 10th aurora was particularly interesting for me due to a thunderstorm in the distance, sadly I was only able to take 1h worth of exposures, and thus, the video is rather short, this is from 1h30 to 2h30, If only I could've been on site 2h early.

Nature's Own Light Show
On the night of August 12, a strong geomagnetic storm triggered spectacular display of Northern Lights which was visible as far south as Georgia. This concided with the Perseid Meteor shower reaching its peak with up to 90-100 per hour. It was an incredible opportunity to record this event. Perseid Meteors rained through the sky in a blazing display of celestial fireworks, leaving dust trails from the comet Swift-Tuttle. what made the night truly unforgettable was an unexpected geomagnetic storm that lit up the northern sky with a dazzling display of colorful auroras.

Real time 4K video - Aurora Borealis/Northern Lights peak activity 11th October 2024
The high activity segment of the aurora borealis peak, the event started on the night of the 10th October 2024 and peak activity was around midnight (so into the 11th) for half an hour when the solar activity was measuring approximately 1600nT, similar to the peak during the aurora of 10th May earlier in the year.
As we approach the sun's solar maximum, events like this will likely become more frequent and viewable further south in latitude (in the northern hemisphere) and further north (in the south hemisphere) as more sunspots develop on the sun's surface and eject Coronal Mass Ejections towards our planet.

Re: Video Submissions
22 minutes around the nucleus of a comet
As comet C/2023 A3 (Tsuchinshan-ATLAS) passes by, I'd like to take this opportunity to present my latest stereoscopic 3D film on the nucleus of a comet (release oct 24). This film gives you a detailed look at the product of predominantly solar erosion on the surface of a comet, as if you were in a spacecraft circling, approaching and landing on the comet.
The 3D reconstruction of small bodies is fundamental to the study of their physical properties, starting with their volume, which gives access to their density and thus to the formation processes. The study of their surfaces (and those of planets) and evolutionary processes requires quantitative data (height of cliffs, depth of basins, craters, wells, etc.). This is particularly the case for thermal modeling (energy received and integrated by the body) to determine lighting conditions. From an operational point of view, placing a vehicle on these surfaces (site selection) or operating a rover requires 3D reconstruction and stereo vision. To understand the overall shape of small bodies, we need to: understand accretion and evolution processes, know the gravity field (navigation aid). Geomorphological studies of terrestrial planets, asteroids and cometary nuclei require: a better understanding of the geological processes involved, information on internal structure, localized morphological studies at high spatial resolution, understanding of global and local topography, particularly slopes.
This work led to the publication of an article in the scientific journal Monthly Notices of the Royal Astronomical Society (MNRAS), Volume 531, Issue 2, June 2024, Pages 2494-2516, https://doi.org/10.1093/mnras/stae1290 “Detection and characterization of icy cavities on the nucleus of comet 67P/Churyumov-Gerasimenko” by Philippe Lamy, Guillaume Faury, David Romeuf, Olivier Groussin.
This study represents the first confirmation and characterization of SAPs (Subsurface Access Points) on a comet, i.e. cavities 20 to 47 m deep, with evidence of the presence of water ice. These cavities are areas of interest for a potential space probe that could gain direct access to the subsurface materials. We have also correlated the departure of a transient jet, linked to insolation at the bottom of one of these icy cavities, thanks to images and a 3D model associated with a thermal model.
If you want to learn more about the evolution of the comet's surface morphology, you can read this scientific article: “Surface Morphology of Comets and Associated Evolutionary Processes: A Review of Rosetta's Observations of 67P/Churyumov-Gerasimenko”.

Re: Video Submissions
Dynamics of a Comet's Tail
There has been thousands of spectacular images recently taken of Comet Tsuchinshan-Atlas and I have finally joined the party...all be it late!
Imaged on the 23 of October 2024 as it was setting in Spain. Image taken with The Takahashi 180 and asi2400mc pro.
When you compare this comet to many in the past it really does not appear to show a lot of structure...or that is what I thought! While doing the usual comet process I noticed quite a bit of detail showing through the tail and wondered if I was able to see any movement. Surprisingly the tail was pretty dynamic and was showing a coil of debris moving quite quicky down through the tail.
The animation is a timelapse of 29x 30s frames with a OSC camera. Please click the image to see the animation
https://www.astrobin.com/lzmigw/0/rawth ... c&animated
The comet at this stage still shows the 'antii' tail very nicely but significantly more diffused from a few days ago .
Thanks for looking
Peter Shah
