An example of the photographic precision of the equatorial telescope at the Qingdao Observatory.
Abstract
The planetary nebula NGC 2346 has been observed for the astrophysical study using the 32/358 cm telescope of the Quingdao Observatory in April 1987. The photometries for the planetary nebula and five stars within ten arcminutes around have been made using the PDS in Nanking. Meanwhile, the positions of these stars were measured and processed for the survey of the photographic positional accuracy. The authors obtained a good result, which shows a promising future for the radio star photographic position observations with this telescope.
