A Ritchey-Chr\u00e9tien uses two hyperbolic mirrors: the design of virtually every professional observatory. The result is a large, coma-free field of view without a corrector: stars remain round all the way to the edges of the sensor.<\/p>\n\n\n\n De 3 inch focuser belicht ook grote sensoren zonder vignettering en roteert voor de juiste beelduitsnede zonder de camera-trein te demonteren. De tilt-adapter lijnt de sensor exact haaks uit en de kwartsspiegels houden het brandpunt stabiel bij temperatuurwisselingen.<\/p>\n\n\n\n De interne baffles houden het contrast hoog; de Losmandy-zwaluwstaart hoort op een zware montering in de EQ8-klasse.<\/p>\n<\/div>\n<\/div>\n\n\n\n Het Omegon Pro UHC 2 inch filter (89 euro) haalt emissienevels naar voren en de Omegon Powerbank 10k 12V (39,90 euro) voedt de opstelling op locatie.<\/p>\n\n\n\n Wel: veeleisende astrofotografen en kleine sterrenwachten die maximale beeldschaal in een gesloten buis willen. Niet: wie naar 12 inch en groter wil; daar begint de truss-lijn, met betere ventilatie en minder gewicht per centimeter opening. Twijfel je tussen de modellen? De Choice assistant<\/a> helpt.
