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 Ronde sterren tot aan de rand betekenen minder correctiewerk in de nabewerking en meer bruikbare frames per nacht. De ge\u00efntegreerde baffles onderdrukken strooilicht, zodat het contrast ook onder een minder donkere hemel overeind blijft.<\/p>\n\n\n\n De Losmandy-zwaluwstaart koppelt stabiel aan serieuze monteringen; op f\/8,9 is nauwkeurig volgen of guiden de sleutel tot succes.<\/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) houdt montering en camera een nacht op spanning.<\/p>\n\n\n\n Wel: astrofotografen die voor de laagste instapprijs het professionele RC-ontwerp willen proberen. Niet: wie direct de zwaarste camera-trein en sensorkanteling wil beheersen; de carbon-uitvoering met linear bearing focuser en tilt-adapter is daarvoor gebouwd. Twijfel je tussen de modellen?
