La Rose de Sandrine

La Rose de Sandrine

Pour ma dernière cible au foyer, lors des RAAGSO 6, je me suis laissé influencer par Sandrine, une amie astramette qui était sur place. A chaque sortie, elle ne manque pas, avec le dobson, de cibler cet amas ouvert qu'elle adore. Découvert par Caroline Herschel, il est populairement appelé la Rose de Caroline. Catalogué NGC 7789, il se trouve dans la constellation de Cassiopée.

L'humidité était encore présente pour cette dernière nuit, bien que plus atténuée que les nuits précédentes. Il a quand même fallu que je passe le sèche-cheveux sur le secondaire par deux fois… et malgré un tri pointilleux des poses, j'ai dû en laisser passer deux ou trois qui étaient atteintes. A noter dans mon calepin : me fabriquer un pare-buée !

Voici donc le résultat qui, ma foi, a son charme ;)

53 poses de 2 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.
