    摘要: A polar axis finder for an equatorial mounting telescope has an objective lens and a focus mirror having a Polaris collimating mark thereon disposed at a focal point of the objective lens. A time scale cylinder has a time scale thereon and the focus mirror is fixedly mounted within one end portion thereof. The time scale cylinder and the focus mirror can be rotated relative to a month scale cylinder having a date scale and an autumnal equinox point mark thereon, the latter being placed in alignment with a corresponding index provided on the telescope whereby polar axis alignment can be readily achieved with high accuracy.
