Choisir son télescope - vidéo Astronogeek

Rédigé par NGC44 53 commentaires

Astronogeek est une chaîne Youtube vieille d'à peine 1 an qui nous parle d'astronomie, d'anecdotes et d'observation du ciel en général. Arnaud maîtrise plutôt bien ses sujets du coup je renvoie ceux qui cherchent un premier instrument vers sa vidéo :

Après avoir présenté et vulgarisé la notion d'ouverture ainsi que les différentes formules de télescopes et de montures, Astronogeek nous conseille... un dobson ! Ce avec quoi je suis plutôt d'accord, car même si je suis adepte des montures équatoriales, le dobson est probablement l'instrument le plus simple et naturel à manipuler tout en étant peu cher.

Autre point important mentionné dans la vidéo : consultez un club d'astronomie ! Même pour une soirée, cela vous permet de rencontrer des gens, avoir des conseils, vous faire une idée de la taille (et du poids) des instruments, et donc éviter de dépenser des milliers d'euros pour rien.

Quel type de dobson peut être intéressant? Quelle diamètre?

Salut, je pense qu'en Dobson tu peux viser un diamètre de 200mm, f/d de 5, le prix reste raisonnable et les performances sont excellentes !
