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>2 inches (50.8 mm)<\/strong>. The version number is <strong>7774<\/strong> : The factor and diameter must be considered together when making a selection.<\/p>\n<h3>Doublet ED et deux formats d\u2019oculaires<\/h3>\n<p>Le verre ED contribue \u00e0 r\u00e9duire les aberrations chromatiques. Les deux lentilles sont trait\u00e9es multicouches. Le coulant 2 pouces re\u00e7oit les accessoires de ce format et un adaptateur 1,25 pouce est fourni. Le bo\u00eetier poss\u00e8de une surface facilitant la prise en main ainsi qu\u2019une gorge de s\u00e9curit\u00e9.<\/p>\n<h3>Une cellule optique d\u00e9montable<\/h3>\n<p>La partie optique inf\u00e9rieure peut \u00eatre d\u00e9viss\u00e9e et mont\u00e9e sur un oculaire 2 pouces compatible. Omegon annonce alors un facteur voisin de 1,5x, qui d\u00e9pend du montage, au lieu du facteur nominal 2x de l\u2019ensemble complet. Le fabricant indique un filetage pour filtres 2 pouces sur la partie inf\u00e9rieure et l\u2019adaptateur r\u00e9ducteur. V\u00e9rifiez les filetages et le d\u00e9gagement avant assemblage.<\/p>\n<h3>Technical specifications<\/h3>\n<table style=\"width:100%;max-width:100%;border-collapse:collapse\">\n<tbody>\n<tr>\n<th style=\"text-align:left;padding:8px\">Brand<\/th>\n<td style=\"padding:8px\">Omegon<\/td>\n<\/tr>\n<tr>\n<th style=\"text-align:left;padding:8px\">Reference<\/th>\n<td style=\"padding:8px\">7774<\/td>\n<\/tr>\n<tr>\n<th style=\"text-align:left;padding:8px\">Rated amplification<\/th>\n<td style=\"padding:8px\">2x<\/td>\n<\/tr>\n<tr>\n<th style=\"text-align:left;padding:8px\">Flow on the telescope side<\/th>\n<td style=\"padding:8px\">2 inches (50.8 mm)<\/td>\n<\/tr>\n<tr>\n<th style=\"text-align:left;padding:8px\">Number of lenses<\/th>\n<td style=\"padding:8px\">2<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Choice Questions<\/h3>\n<p><strong>How do you calculate the magnification?<\/strong> Divide the telescope's focal length by that of the eyepiece, then apply the nominal magnification factor of this amplifier as intended for its configuration. Very high magnification can reduce apparent brightness and accentuate turbulence: choose a reasonable combination for your instrument.<\/p>\n<p><strong>Is it compatible with any camera?<\/strong> The insertion diameter alone is not enough to guarantee compatibility with a camera. You must also check the mount, the focal length, the field of view, and whether the camera can be focused.
