De klassieke Cassegrain-opbouw, parabolische hoofdspiegel met vangspiegel, levert hoge vergroting en hoog contrast voor planeten, dubbelsterren en maankraters, zonder chromatische aberratie.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De lange brandpuntsafstand maakt hoge vergrotingen bereikbaar met gewone oculairs en geeft direct een bruikbare beeldschaal voor planeetfotografie.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Voor balkon en vaste opstelling<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Met een 7 mm oculair sta je op 264x, ruim binnen het praktische maximum van ongeveer 300x. Het collimatievaste, onderhoudsarme ontwerp en het compacte formaat maken deze buis ideaal voor balkongebruik en permanente opstellingen met beperkte ruimte.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">De 2 inch achteraansluiting neemt focuser en accessoires naar keuze; stofkap en Vixen-zwaluwstaart zitten erbij.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Included<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Cassegrain-optiek 154\/1848 met parabolische hoofdspiegel<\/li>\n\n\n<li>2-inch rear connection<\/li>\n\n\n<li>Dust cover<\/li>\n\n\n<li>Vixen-style dovetail<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Featured accessories<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Het Omegon Cronus 7 mm oculair (79 euro) zet 264x neer voor planeetdetail en het Omegon 7-21 mm zoomoculair (69 euro) dekt traploos 88x tot 264x. Een Omegon Premium maanfilter (19,90 euro) dempt de felle Maan.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">For whom yes, for whom no<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Wel: planeetliefhebbers en beginnende planeetfotografen die veel brandpunt in weinig ruimte willen. Niet: wie deep-sky of breedveld zoekt; op f\/12 is het beeldveld daarvoor te smal. Twijfel je tussen de modellen? De <a href=\"\/en\/telescope-selection-aid\/\">Choice assistant<\/a> helpt.
