ЧТО ОЗНАЧАЕТ СЛОВО ZENITH TELESCOPE
Зенитный телескоп
Зенитный телескоп - это тип телескопа, который предназначен для точечной прямой или близкой к зениту. Они используются для точного измерения положения звезд, для упрощения конструкции телескопа или для обоих. Классический зенитный телескоп, также известный как зенитный сектор, использует сильное алтазимовое крепление, оснащенное регулировочными винтами. Чрезвычайно чувствительные уровни прикреплены к держателю телескопа для измерения угла, а телескоп имеет окуляр с микрометром. Они используются для измерения малых разностей зенитного расстояния и используются при определении астрономической широты. Другие типы зенитных телескопов включают Монумент Большого Огня Лондона, который включал центральный вал, предназначенный для использования в качестве зенитного телескопа. Высокоточные зенитные телескопы также использовались до начала 1980-х годов для отслеживания положения северного полюса Земли, например. Положение оси вращения Земли. С тех пор радиоастрономические измерения квазара также измерили ось вращения Земли на несколько порядков точнее, чем оптическое отслеживание.
