Bonjour à tous,

Petit essai sur M51, aussi connue comme la galaxie du Tourbillon est un couple de galaxies, à environ 8,4 Mpc de la Terre dans la constellation des Chiens de chasse, composé d'une galaxie spirale régulière massive dont le diamètre est estimé à 100 000 années-lumière et d'une petite galaxie irrégulière qui commence à être visible assez haute dans le milieu de nuit, j'ai eu 2.5h d'intégration.

Ayant un Canon 6d, un plein format, ma taille du capteur est très gros comparer à un appareil photo APS-C donc pour les petits objets comme M51, il faut recadrer beaucoup l'image afin de pouvoir voir de près, mais l'image est beaucoup moins nette, et j'ai peut être un peu abusé sur le traitement avec la deconvolution qui permet de réduire les étoiles un peu et de dégager du détails. 😂😅

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.
