Un beau rapprochement ne se reproduisant que tous les huit ans, le beau temps étant là, et me voici à nouveau dans le jardin, malgré la Lune et les lampadaires du village, afin de tenter d’immortaliser l’événement : la rencontre de la planète Vénus et de l’amas d’étoiles ouvert des Pléiades (les Sept Sœurs) dans la constellation du Taureau.

Cette fois, j’ai sorti le petit setup, composé de la StarAdventurer et de mon APN.

J’ai pas mal tâtonner pour trouver les bons réglages mais au moment du crépuscule astronomique vers 22 h, je pus lancer une série de poses durant près d’une heure… un peu avant 23 h, ma cible commençait à être un peu basse sur l’horizon et le fond du ciel s’éclaircissait sur les clichés.

J’ai acquis 233 poses très courtes mais je n’en ai utilisé que la moitié pour l’image ci-dessous. Eh oui, j’avais oublié qu’une planète bouge plus vite que les étoiles… et sur une heure, cela se voit.

Au final, je n’ai retenu qu’une vingtaine de minutes cumulées et vous en présente le résultat.

Photo prise le 3 avril 2020 à Ayguemorte-les-Graves (33) – Canon 7D avec objectif SIGMA APO DG 70/300, focale 133 mm, ouvert à f/5.6, sur monture StarAdventurer (sans goto, ni autoguidage).

112 poses de 10 s, ISO 1000, 23 DOF, Iris et Toshop.

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.
