Paperback. Condizione: New. Print on Demand. This book is a collection of observations of stars in the Northern Hemisphere taken in the late 1800s using the transit circle instrument at the Hamburg Observatory in Germany. The stars observed were between declinations +80 and +90 degrees and were observed in both right ascension and declination. The observations were made by the astronomer R. Schorr with the help of Dr. A. Scheller using the new Repsold Meridian circle of the Hamburg Observatory. The book contains a catalogue of 344 stars, providing their positions and magnitudes. The observations were used to determine the accurate positions of the stars, and the resulting catalogue is valuable for astronomers working in the field of astrometry. The observations also provide information on the proper motions of the stars, which can be used to study the dynamics of the Milky Way.
