Tube optique Sky-Watcher 100EDX Evostar<\/h1>\n

 <\/p>\n

Lunette apochromatique l’observation plan\u00e9taire et la photo du ciel profond<\/strong><\/h2>\n

Tout savoir sur la lunette Sky-Watcher EvoStar 100EDX<\/h4>\n

Sky-Watcher propose la gamme EvoStar EDX de 80 \u00e0 150mm pour couvrir un large panel de besoin. L’EvoStar 100EDX est de diam\u00e8tre interm\u00e9diaire et s’adresse aux amateurs recherchant un instrument polyvalent :\u00a0\u00e0 la fois pour l’observation des plan\u00e8tes ET la photo du ciel profond<\/strong>. Gr\u00e2ce \u00e0 son rapport de focale \u00e0 f\/7 elle permet la pratique de l’astrophotographie. N\u00e9buleuses et galaxies seront alors des cibles de choix. Sa qualit\u00e9 optique d’un niveau \u00e9lev\u00e9, gr\u00e2ce \u00e0 la bonne correction du chromatisme, ravira plus d’un amateur.\u00a0La Lune, Jupiter et Saturne vous offriront un beau spectacle \u00e0 100mm de diam\u00e8tre<\/strong>, n’h\u00e9sitez pas \u00e0 utiliser un grossissement \u00e9lev\u00e9 sur un tel instrument.<\/p>\n

Syst\u00e8me achro et apo-chromatique<\/figcaption><\/figure>\n

Pour obtenir le pr\u00e9cieux qualificatif “APO”, un r\u00e9fracteur doit corriger les aberrations chromatiques primaires et secondaires, inh\u00e9rentes \u00e0 tous les syst\u00e8mes dont les rayons lumineux traversent un \u00e9l\u00e9ment optique. Dans le cas de l’EvoStar 100EDX, un doublet compos\u00e9 d’un \u00e9l\u00e9ment en verre ED (du fabricant reconnu japonais Hoya) r\u00e9duit le chromatisme pour limiter consid\u00e9rablement l’apparition de lis\u00e9r\u00e9s color\u00e9s sur les plan\u00e8tes ou la Lune. L’utilisation de traitements multi-couches sur toutes les surfaces limite consid\u00e9rablement les pertes dues \u00e0 la travers\u00e9e de l’objectif, ce qui rend\u00a0l’EvoStar 100EDX lumineuse et plus contrast\u00e9e que des lunettes classiques moins bien corrig\u00e9es<\/strong>. Le traitement “Metallic High-Transmission” (MHC) est d\u00e9pos\u00e9 sur les surfaces air-verre assurant des r\u00e9sultats \u00e9poustouflants (transmission proche de 99.5%<\/strong>).<\/p>\n

Gr\u00e2ce \u00e0 son rapport de focale (f\/7) la lunette\u00a0Sky-Watcher EvoStar 100EDX est particuli\u00e8rement int\u00e9ressante pour la photographie du ciel profond<\/strong>. En combinaison, par exemple, avec un appareil photo num\u00e9rique grand format (correcteur\/r\u00e9ducteur conseill\u00e9), pointez la lunette vers les plus beaux ou complexes objets du ciel profond. De plus\u00a0un tel diam\u00e8tre r\u00e9colte 56% de plus de lumi\u00e8re qu’un r\u00e9fracteur de 80mm<\/strong>.<\/p>\n

Porte-oculaire 2.6″ Crayford Dual Speed 10:1<\/h4>\n
Lunette apochromatique Sky-Watcher EvoStar 100EDX f\/7<\/figcaption><\/figure>\n

La gamme Sky-Watcher EvoStar dispose d’un porte-oculaire de qualit\u00e9 car pour \u00eatre coh\u00e9rent avec l’optique et fournir de bons r\u00e9sultats en astrophotographie (ou la mise au point a une place primordiale) la m\u00e9canique doit \u00eatre optimis\u00e9e. Le porte-oculaire est\u00a0un Crayford de grande capacit\u00e9 de charge<\/strong>\u00a0pour les plus gros capteurs. Au format 2.6″ (66mm) en entr\u00e9e,il est \u00e0 la fois\u00a0robuste et pr\u00e9cis gr\u00e2ce \u00e0 une d\u00e9multiplication 10:1<\/strong>. Une vis de serrage permet de maintenir la mise au point suivant l’orientation du tube optique.La sortie du porte-oculaire est rotative \u00e0 360\u00b0 sans perte de votre mise au point<\/strong>\u00a0pour vous aider \u00e0 trouver le meilleur cadrage.<\/p>\n

Pour r\u00e9pondre aux exigences des astronomes amateurs,\u00a0le tube optique est enti\u00e8rement r\u00e9alis\u00e9 en aluminium<\/strong>\u00a0et usin\u00e9 avec grande pr\u00e9cision sous CNC (machine \u00e0 commande num\u00e9rique). Aucune pi\u00e8ce plastique n’est utilis\u00e9e! La solidit\u00e9 est donc au rendez-vous comme l’esth\u00e9tique particuli\u00e8rement r\u00e9ussi.\u00a0L’int\u00e9rieur est noirci et baffl\u00e9 pour limiter l’intrusion de lumi\u00e8res parasites<\/strong>. Deux colliers et une queue d’aronde type Vixen sont inclus pour la fixation \u00e0 votre monture.<\/p>\n
