It's a Pita Parka.
Frank SchlesingerBorn 11 May 1871; died 10 Jul 1943 at age 72.American astronomer who pioneered in the use of photography to map stellar positions and to measure stellar parallaxes, which could give more precise determinations of distance than visual ones, and with less than one hundredth as much time at the telescope. He designed instruments and mathematical and numerical techniques to improve parallax measurements. He published ten volumes of zone catalogs, including some 150,000 stars. He compiled positions, magnitudes, proper motions, radial velocities, and other data to produce the first edition and, with Louise Jenkins, the second, of the widely-used Bright Star Catalogues, making Yale a leading institution in astrometry. He established a second Yale observatory in South Africa. |
