Abstract

The invention discloses a polar axis calibration mechanism of an equatorial telescope and a calibration method of the polar axis calibration mechanism. According to the polar axis calibration mechanism of the equatorial telescope, the equatorial telescope comprises a base, an hour angle assembly, a drift angle assembly, a latitude adjusting mechanism connected with the hour angle assembly, a horizontal direction hand wheel arranged at the lower end part of the base, and an hour angle locking handle wheel arranged at the tail end of the hour angle assembly; the polar axis calibration mechanism comprises a mounting plate, a connection seat, a polar axis lens and a gradienter; one end of the mounting plate is fixedly arranged at one side part of the drift angle assembly; the connection seat is connected with the other end of the mounting plate; the polar axis lens is arranged in the mounting plate and the connection seat in a manner of vertically penetrating and can be rotated in the mounting plate and the connection seat; the polar axis lens is internally and fixedly provided with a dividing plate with clock scales; the gradienter is fixedly arranged on the upper end face of the connection seat. The calibration mechanism is simple and reasonable in structure; the calibration of a polar axis can be rapidly and conveniently realized.

Description

technical field [0001] The invention relates to an optical instrument, in particular to a polar axis calibration mechanism applied to an equatorial mount and a calibration method thereof, belonging to the technical fields of astronomy and measurement. Background technique [0002] An equatorial mount is a common instrument for measuring angles. It is usually used in conjunction with astronomical telescopes for astronomical observations, and provides measurement scientific data for astronomical phenomena and astronomical research. When the equatorial mount is in use, the polar axis needs to be aligned with the north celestial pole first, that is, the polar axis is calibrated. Ideally, after it is completely aligned, the telescope is facing any star, and the declination does not need to be adjusted again. Just let the telescope Rotate at a constant speed in the direction of right ascension (or hour angle) according to the speed of the star, so that the star can be kept in the ...
