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.
Click on them to go directly to the video.
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.
