<\/a><\/p>\nKortere brandpuntsafstand bereiken<\/h3>\n
Deze unieke lens is speciaal ontworpen voor Celestron Schmidt-Cassegrain telescopen en vermindert de brandpuntsafstand en f\/verhouding van je telescoop met 37%. Hierdoor verandert je telescoop met een f\/10-verhouding in een snellere telescoop met f\/6.3, en een f\/11-verhouding in f\/7. Niet geschikt voor EdgeHD-modellen.<\/strong><\/p>\nVoor visueel gebruik betekent dit dat je met dezelfde oculairen een lagere vergroting en een breder beeldveld krijgt.
Voor fotografie krijg je eveneens een breder beeldveld en veel kortere belichtingstijden.<\/p>\n
Gebruik<\/h3>\n
De Reducer\/Corrector is eenvoudig te installeren door de lens op de achterzijde van je Schmidt-Cassegrain telescoop te schroeven (of op de reducerplaat van de C11 en C14).
Zodra deze is gemonteerd, kun je extra accessoires toevoegen zoals T-adapters, een 1.25 inch visual back, een stardiagonaal of een off-axis guider.<\/p>\n
De Reducer\/Corrector kan ook worden gebruikt voor terrestrische digiscopie. Dankzij de snellere f\/verhouding kun je langzamere film gebruiken of bij minder licht fotograferen en toch een correcte belichting krijgen.
De volledig meerlaags gecoate lens zorgt voor maximale lichttransmissie met vrijwel volledige veldverlichting.<\/p>\n
Plaats de kunststof doppen op de lens wanneer deze niet in gebruik is, om stofophoping te voorkomen.<\/p>\n
Behuizing<\/h3>\n
De lens is ondergebracht in gefreesd, zwart geanodiseerd aluminium.
De interne oppervlakken zijn gezwarte en voorzien van antireflectieschroefdraad om het hoogste contrast te garanderen.
De buitenkant heeft een geribbelde (geknurlde) afwerking, wat zorgt voor een uitstekende grip bij het vast- of losdraaien.<\/p>\n
Door het ontwerp vermindert de Reducer\/Corrector een klein beetje van de veldwelving die typisch is voor alle Schmidt-Cassegrain telescopen, maar elimineert deze niet volledig.
Beelden met hoge vergroting tonen een vlakker beeldveld tot aan de rand, zowel visueel als fotografisch.<\/p>\n","protected":false},"excerpt":{"rendered":"
