Pour le moment...nul!

Sincèrement... très decevant! A la première utilisation les images lunaires étaient d'un flou total. Cela va nécessiter soit une re collimation soignée, soit un démontage du barrillet du miroir pour vérifier l'optique au ''couteau''.

Bonjour,

Merci beaucoup d’avoir pris le temps de partager votre expérience. Nous sommes sincèrement désolés d’apprendre votre déception lors de la première utilisation.

Avec un télescope de type Dobson, il est effectivement possible que la collimation nécessite un ajustement après le transport. Un léger désalignement peut rapidement entraîner une image floue.

Cela dit, ce que vous décrivez n’est pas normal une fois l’instrument correctement ajusté, et nous souhaitons vraiment vous aider à obtenir les performances attendues.

Nous vous invitons à nous contacter directement, si le problème persiste après colimation.

Notre objectif est que vous puissiez profiter pleinement de votre télescope, et nous allons vous accompagner jusqu’à ce que ce soit le cas.

Au plaisir de vous aider,
Marika
