NINA erreur au retournement au méridien

[stef28]

Bonjour,

J'utilise la version 3.1.2.3004 avec une monture AZ-GTI et une caméra QHY168C. Ma plateforme ASCOM  et mon driver de monture Syn Scan App Driver sont à jour.
Tout fonctionne très bien sauf quand je fais un retournement au méridien. NINA affiche une erreur ASCOM et le log est le suivant :

Je ne sais pas trop quoi faire pour résoudre mon problème. Est-ce que quelqu'un aurait une idée ?

 

Merci d'avance
