Catalogue Of 1905 Stars For The Equinox 18650 From Observations Made At The Royal Observatory 1861 To 1870
Author: Various

PREFACE. THE publication of this Catalogue marks an epoch in the history of the Observatory. For the first time in that history the Director can feel that the accumulated labours of his predecessors are available for the use of Astronomers, and that the work being done under his own direction is in a healthy and forward state of reduction and pu... more »blication. How heavily the load of arrears pressed upon my predecessor is evidenced by his remarks in the introduction to the Cape Catalogue for i8oo When I assumed the Directorship in 1870, I found myself, with a very limited staif, unexpectedly confronted with the results of 36 years of miscellaneous observing in all stages of reduction, nothing completed, and nothing which could be brought forward for publication and use without a very considerable expenditure of time and skilled labour. Astronomers are greatly indebted to Mr. Stone for the energy ami determination with which he faced the odds against him, and for tho manner in which he cleared off a large share of these arrears by his publication of the Catalogues for 1840 and 1860. Together with the discouragementand vexation which the existence of such arrears gives to an Astronomer who is desirous of pushing forward investigations in which he is more immediately interested, there must also be the feeling that every increase in the delay of publication means a hindrance to the progress of science. How serious those hindrances have been will be evident from the following table, which shows the dates at which the various series of Cape Meridian Observations, made previous to 1870, were published in the form of Star Catalogues r.oo. i 1 ooo. Wr. 9fi . E. s, 701151 a 2 11 Xo blame can be attached to the earlier Cape Astronomers for these delays. Their official instructions were to carry on the same work as at Greenwich, but it did not apparently occur to the authorities at homethat a similar staff to that at Greenwich was required for its regular reduction and publication. There was no Board of Visitors, as at Greenwich, to support the demands of the Astronomer for adequate assistance, and his requests were too often treated with coldness and neglect. Fortunately i more enlightened spirit now prevails, and it is due to the wise liberality of the Admiralty, and to the devotion of his staff, thatH.M. Astronomer isnow able to report that the arrears of publication of the Cape Meridian Observations no longer exist. The services ofMr. J. Power are specially noteworthy in connection with the preparation of the present work for press. Ill INTRODUCTION TO THE CAPE CATALOGUE, 1865. This Catalogue of 1,905 Stars is based on observations made with the Cape Transit-Circle under the direction of Sir Thomas Maclear during the years 1861, 62, 63, 64, the year 1870. J 6j, 66, 67, 68, 69, and part of The Eight Ascensions and Declinations of the Catalogue are given for the Mean Epoch of Observation, reduced without Proper Motion to the Equinox 1 865 o...
