avoir passé une heure trente à régler au petits oignons mon setup, à attacher les cables, à centrer la cible et à régler les paramètres de guidage, j'avais obtenu un truc de ouf quasi parfait, j'appuie sur "demarrer prises de vues" d'eos utility, je me retourne et là d'un seul coup j'entends un cliquettement de feuilles qui tombent à la pelle : LE VENT SE LEVE!!!! je me retourne, mes courbes de guidages dansent la giguent au grés des petites raffales, j'étais tellement écoeuré que j'ai tout laissé sur palce, je suis revenu voir 4 heures plus tard si le vent s'était calmé et là surprise : la cata ... APN Calé contre le trépied de l'HEQ5 après la bascule méridienne : les poses de l'APN m'ont révélé que ma monture patinait depuis 15 minutes!!

Je ne suis pas le premier et cela me rassure un peu, il ne semble pas y avoir de dégats.

Au final, seulement 28 poses de 4 minutes exploitables, 24 poses perdues (étoiles olive/déformées) lors des raffales et du blocage.

Voilà le résultat.

Setup : 80ED + autoguidage PHD2 avec Vivitar 70/300, Canon EOS 4501D défiltré, filtre CLS/clip, 28 brutes 4' 800ISO, 17 darks, 17 flats, 17 offsets).

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.
