L'Hélice sous le vent

En cette soirée du 18 octobre, le ciel était bien dégagé et le vent, bien présent, y était pour quelque chose. Bien sûr, il avait chassé les derniers nuages mais les rafales ont découragé les astrophotographes présents ce soir-là. Obstinée, je décidais quand même de faire cette cible qui me tenait à cœur : NGC 7293, populairement appelée la nébuleuse de l'Hélice (Hélix), dans la constellation du Verseau. Certains l'appellent aussi "l'œil de Dieu".

A cause du vent, j'ai descendu le temps de pose unitaire à 1 mn (au lieu des 2 mn habituelles). J'ai dû jeter un tiers des poses sur les 157 accumulées… cependant le résultat est là et j'en suis plutôt contente ;)

105 poses d'1 mn – 15 dark – 15 flat – 15 offset – ISO 800 – IRIS & 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.
