The Great Refracting Telescope constructed at Dublin for the Vienna Observatory, 1881. 'The greatest refracting telescope in the world has been constructed for the Vienna Observatory by Mr. Howard Grubb, at his celebrated manufactory of astronomical instruments, at Rathmines...We give an Illustration, from a sepia drawing of it by Mr. G. Browning...Desiring to possess the finest telescope which could be procured, the Austro-Hungarian Government commissioned Dr. Edward Weiss, now Director-General of the Observatory at Vienna, to visit all the principal observatories and workshops in the world. He recommended that the task should be confided to Mr. Grubb, who was ordered to construct a refracting telescope of at least 26 in. aperture...The length of the tube is 33ft. 6in., and the aperture is 27in...the whole apparatus is under such control that one person can move it about and manipulate it with the utmost ease...In the foreground is shown an eight-inch Equatorial, similar in size to that which Mr. Grubb exhibited at the last Paris Exhibition...Such an instrument would have been considered very large a few years ago, but a comparison of it with the Vienna telescope will give a good idea of the superior proportions of the latter'. From "Illustrated London News", 1881.
