Bonjour tout le monde,
\nAyant enfin acquis quelques petites comp\u00e9tences dans le traitement avec Pixinsight, je suis en train de retraiter d’anciennes images avec de bien meilleurs r\u00e9sultats qu’auparavant (chinois) et qui de plus, laissent apparaitre des d\u00e9tails invisibles avec mes anciens traitements. C’est ainsi qu’en retravaillant une image de NGC2261, j’ai eu l’attention attir\u00e9e par une toute petite et faible n\u00e9bulosit\u00e9 tr\u00e8s rouge juste au-dessus de l’objet principal, pr\u00e8s du bord sup\u00e9rieur de l’image. Apr\u00e8s v\u00e9rification, il ne s’agit pas d’un artefact de traitement. Comme 2261 est une \u00e9toile tr\u00e8s jeune en formation qui \u00e9met une quantit\u00e9 ph\u00e9nom\u00e9nale de radiations, j’ai pens\u00e9 \u00e0 un objet de Herbig Haro mais je n’ai rien trouv\u00e9 comme r\u00e9f\u00e9rence correspondante.
\nL’un d’entre vous pourrait-il avoir le renseignement?<\/p>\n
