Elle permet de compl\u00e9ter une gamme d\u2019oculaires sans changer d\u2019instrument, notamment pour l\u2019observation de la Lune et des plan\u00e8tes. Son coulant c\u00f4t\u00e9 t\u00e9lescope est au format <strong>1.25 inches (31.75 mm)<\/strong>. The version number is <strong>32970<\/strong> : The factor and diameter must be considered together when making a selection.<\/p>\n<h3>Quatre \u00e9l\u00e9ments et traitements multicouches<\/h3>\n<p>Cette version Premium emploie une optique \u00e0 quatre lentilles avec correction apochromatique annonc\u00e9e par Omegon. Les traitements multicouches limitent les r\u00e9flexions parasites. Le bo\u00eetier en aluminium poss\u00e8de une zone de prise en main caoutchout\u00e9e, utile pour manipuler l\u2019accessoire dans l\u2019obscurit\u00e9. La bague de compression r\u00e9partit le serrage autour de l\u2019oculaire plut\u00f4t que de laisser la vis porter directement sur son coulant.<\/p>\n<h3>Pour le visuel et l\u2019imagerie plan\u00e9taire<\/h3>\n<p>La Barlow se place entre le t\u00e9lescope et l\u2019oculaire ou une cam\u00e9ra correctement adapt\u00e9e. Le facteur 5x est \u00e0 choisir selon la focale de d\u00e9part, l\u2019\u00e9chantillonnage recherch\u00e9 et les conditions atmosph\u00e9riques.

You must also check the mount, the focal length, the field of view, and whether the camera can be focused.
