Nouveau traitement de photos prises l'année dernière lors d'un déplacement dans l'hémisphère sud. Cette constellation de l'hémisphère céleste sud est visible depuis les deux hémisphères. Elle est située dans une région qui comporte énormément d'étoiles, et il n'est pas aisé de pouvoir la mettre en évidence sans apporter des artifices de traitement. Cette version n'a aucun apport, j'ai tenté de respecter les luminosité de chaque étoile fixée par le capteur. Les photos ont été réalisées à l'aide de matériels simples (Star Adventurer sur un pied photo + téléobjectif 100mm macro) vacances et voyage oblige 😎

Voici donc la constellation dans sa totalité.

J'espère que le résultat vous plaira 😊

En version E, un zoom sur le "Corona Australis Molecular Cloud".

New processing of photos taken last year during a trip to the Southern Hemisphere. This constellation of the southern celestial is visible from both hemispheres. It is located in an area witch has a lot of stars, and it is not easy to be able to highlight it without providing artifices of treatment. This version has no extra software contribution, I tried to respect the brightness of each star fixed by the sensor. The photos were taken using simple materials (Star Adventurer on a photo stand + telephoto 100mm macro 😎 ).

Here is the constellation in its entirety.

I hope you enjoy the result 😊

In version E, zoom in on the "Corona Australis Molecular Cloud".

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.
