Animation de l'éclipse solaire du 21 août 2017 aux USA (total solar eclipse animation)

Link: http://monsiteastroperso.free.fr/spip.php?article67

Animation GIF réalisée avec Gimp à partir de 42 captures prises pendant l'éclipse totale de soleil du 21 août 2017 aux USA. La fonction interpolate de Virtualdub a permis de fluidifier un peu l'animation.

La première version correspond à la première phase de l'éclipse jusqu'à la totalité.

La seconde montre l'éclipse dans son intégralité.

Pour la 3e version, j'ai joué avec les courbes de photoshop pour mettre en évidence les taches solaires ; j'ai ajusté l'alignement des images pour limiter les sursauts.

Les images de l'éclipse partielle sont prises à 1/640e de secondes, celles de la totalité au 1/320e et au 1/160e, le tout à 100 iso.

L'éclipse partielle a débuté à 10h25 locales (16h25 TU).

La phase de totalité a duré 2 minutes 21 secondes entre 11h 47' 33" et 11h 49' 54".

L'éclipse partielle s'est terminée à 13h14 locales

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
