Fit HEADER - Rotateur

[G Le Mouellic]

Bonjour,
Serait-il possible d'avoir dans le HEADER l'angle du Rotateur afin de pouvoir facilement le retrouver d'une session à l'autres pour l'imagerie de même objets d'une nuit à l'autre?
En sachant que le rotateur ne tourne que de +90 ou - 90 ° on ne peut le faire correspondre à l'angle de l'image qui est sur 360 ?

C'est de quel rotateur ?
Y a vraiment rien dans le fichier FITS ?
Il est possible que le format CPA le gere mais pas le FITS ... mais ca m'etonne qd meme.

Alors le rotateur c'est le PrimaluceLAB ARCO 3"
C'est la dernière version de prism de 11 que j'ai installé

voici les données FIT que j'ai:
