Lors de cette superbe nuit du 13 mai à Tauxigny, lors de la rencontre NAT 2015, j'ai voulu impérativement pointé la galaxie NGC 4725 dans la constellation de la Chevelure de Bérénice, car cet objet ne faisait que m'échapper depuis le début de la saison à cause des caprices de la météo. Au vu de ce ciel étoilé, je l'ai donc pointé et j'ai lancé les poses dès le crépuscule astronomique.

Malheureusement, j'ai été trop gourmande… j'aurais dû poser toute la nuit car la galaxie est assez lointaine et demande du signal pour bien faire ressortir les détails de cet univers-île au bras unique. J'ai changé de cible en cours de route et aujourd'hui, je le regrette bien. Mais le mal est fait, on ne peut pas revenir en arrière et je devrais me contenter de cette image… peut-être que l'année prochaine j'y reviendrais ;)

On peut y voir plusieurs galaxies dont NGC 4725, la plus grande, NGC 4747 en haut à droite, NGC 4712 en dessous de NGC 4725, pour les plus grandes, et tout un tas de tachouilles flous.

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.
