mais si je regarde les images prises dans les mêmes conditions avec mon ASI1600MC j'ai bien le champ bayerpat
intéressant ça.... les matrices me poursuivent !!!
@Steph 
peux tu vérifier si tu as ce champ dans l'entete FITS de tes images avec la 2600 TheSky et drivers Ascom ?
la différence c'est qu'avec la 1600 c'est le driver ZWO natif qui est utilisé par TheSkyX, alors qu'avec la 533 c'est le driver Ascom car le ZWO natif fait planter TheSkyX, donc peut etre est ce la raison pour laquelle le champ BAYERPAT n'est pas précisé ....
