Bonjour,
\nVoici une image test r\u00e9alis\u00e9e ce mercredi 9 avril 2014 depuis La Fosse avec la camera ST10XME au foyer de la lunette Televue NP101IS. Elle pr\u00e9sente la galaxie M108 en haut de l’image et la n\u00e9buleuse plan\u00e9taire M97 dans le bas. Il s’agit d’un test d’autoguidage pour v\u00e9rifier la qualit\u00e9 du suivi de la monture Takahashi NJP avec ce mode. Le test s’est av\u00e9r\u00e9 concluant malgr\u00e9 les conditions de prise de vue m\u00e9diocres, de nombreux cirrus \u00e9clair\u00e9s par un premier quartier de Lune donnant un ciel vraiment laiteux. 13 poses de 5 minutes en binning 1×1 \u00e0 -20 dg prises \u00e0 travers un filtre rouge composent cette image pr\u00e9sent\u00e9e \u00e0 pleine r\u00e9solution. Le traitement a \u00e9t\u00e9 effectu\u00e9 sous CCDSoft 5 avec un compositage en mode \u00ab\u00a0average\u00a0\u00bb et la finition a \u00e9t\u00e9 faite sous Photoshop CS2. Comme je n’avais pas pr\u00e9vu d’exploiter les captures, je me suis content\u00e9 de r\u00e9cup\u00e9rer d’anciens flats et darks, ce qui explique notamment l’ombre circulaire visible juste au dessus du hiboux.
