The Great Birr 6 foot Telescope

Armagh Observatory

This contemporary photograph shows Lord Rosse's giant 6 foot telescope in its heyday with an observer situated on a gantry at the top of a wall. It used a rather crude mounting and could only observe close to the meridian. T.R. Robinson favoured an equatorial mounting for this telescope but it appears that Lord Rosse found this too difficult to implement for such a cumbersome telescope.
