Description

The "dust belt" and Bok globules in the center hole of the Rosette Nebula.

This image is a crop of the full version of the Rosette Nebula, but with a slightly different processing (contrast, colors...) in order to show more details in the dusty formations.

Insofar as it is a different processing, and that this area is specialy beautiful, I believe it deserve a specific image ! :)

-------------------------------------------------------------------

La grande bande de poussière qui parcourt le cœur de la nébuleuse de la Rosette. On peut y apercevoir également de nombreux "globules de Bok", au sein desquels se forment de futures étoiles...

Cette image est un crop de la version full de mon image de la nébuleuse de la Rosette mais avec un traitement spécifique légèrement différent (sur les couleurs, le contraste...) afin de mettre en valeur au mieux les bandes de poussières.

Dans la mesure où le traitement est différent et que cette zone est particulièrement belle, il m'a semblé justifié de la présenter sous une image distincte ! :)
