Description

EOS 5D Mark IV - EF 100mm Macro L IS USM @F/4.5 - 800ISO - 40 x 30s

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".
