Le 200\/800 poss\u00e8de un \"gros\" chercheur 8x50, qui se fixe sur le t\u00e9l\u00e9scope par un syst\u00e8me de queue d'arronde. J'ai \u00e9t\u00e9 tr\u00e8s surpris par sa taille, ayant d\u00e9but\u00e9 avec un chercheur 5x24 sur mon 130\/900, remplac\u00e9 ensuite par un 6x30. Il a fallu r\u00e9gler deux choses pour pouvoir utiliser le chercheur : tout d'abord sa nettet\u00e9, et ensuite son alignement comme pour tout chercheur.<\/p><\/div><\/div>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

En pointant le chercheur sur Jupiter (qui avait le bon go\u00fbt de passer par l\u00e0), je me suis aper\u00e7u qu’il donnait une image toute floue. La mise au point peut \u00eatre r\u00e9gl\u00e9e, il a donc fallu commencer par l\u00e0. Le chercheur poss\u00e8de une bague de blocage de la mise au point, il faut donc tout d’abord d\u00e9verouiller la bague. Ensuite, on fait la mise au point en tournant l’objectif du chercheur, jusqu’\u00e0 ce qu’on obtienne une image nette et piqu\u00e9e. Ceci fait, il n’y a plus qu’\u00e0 verrouiller la bague, et voil\u00e0 ! Il n’est plus n\u00e9cessaire d’y toucher par la suite !<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Maintenant, on proc\u00e8de \u00e0 l’alignement du chercheur avec le tube. Le support poss\u00e8de une vis argent\u00e9e \u00e0 ressort qui sert au maintien du chercheur, et deux vis plastiques noires sur lesquelles il faut agir. Donc :<\/p>

– on met un oculaire (\u00e0 faible grossissement) dans le t\u00e9l\u00e9scope<\/p>

– ensuite, en regardant uniquement dans l’oculaire<\/span><\/strong>, on vise un objet lointain (clocher, toit, montagne…)<\/p>

– on fait la mise au point et on le centre le mieux possible dans l’oculaire<\/p>

– maintenant, on regarde dans le chercheur, et en agissant uniquement sur les deux vis noires<\/span><\/strong>, on met l’objet vis\u00e9 au centre du r\u00e9ticule<\/p>

– \u00e9ventuellement on peut affiner l’op\u00e9ration avec un oculaire qui grossit plus pour augmenter la pr\u00e9cision du r\u00e9glage, mais \u00e7a n’est pas absolument n\u00e9cessaire.<\/p>

Remarque :<\/strong><\/p>

le syst\u00e8me de r\u00e9glage de ce chercheur est vraiment g\u00e9nial, compar\u00e9 au r\u00e9glage \u00e0 3 vis pr\u00e9sent sur mes pr\u00e9c\u00e9dents chercheurs, qui \u00e9tait vraiment tr\u00e8s p\u00e9nible \u00e0 utiliser !<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
