QUE SIGNIFIE NEWTONIAN TELESCOPE EN ANGLAIS
Télescope newtonien
Le télescope newtonien est un type de télescope réfléchi inventé par le scientifique britannique Sir Isaac Newton, utilisant un miroir primaire concave et un miroir secondaire diagonal plat. Le premier télescope réfléchissant de Newton a été achevé en 1668 et est le premier télescope réfléchissant fonctionnel connu. Le design simple du télescope newtonien les rend très populaires auprès des téléspectateurs amateurs.
