Hickson 57 is a compact group of eight galaxies in the Constellation of Leo that are interacting and possibly merging. This group was first named "The Septet" by Ralph Copeland (1837-1905), while employed as an observer under Lord Rosse, Earl of Parsonstown, Ireland.

He probably first observed the group while using the 72-Inch "Leviathan of Parsonstown" at Birr Castle. This speculum mirror telescope, built by Lord Rosse, enabled Copeland to observe this cluster with relative ease.

Ralph Copeland later went on to take spectral measurements of the supernova S Andromeda in 1885, travel overseas to view the conjunction of Venus with the sun, and once visited the famous 19th century optician, Alvan Clark, in the United States. He also served as Astronomer Royal of Scotland between 1889-1905.

Good capture there Dave, It's nice to see a bit wriitten from the history of astronomy, which must not be forgotten about !

Imagine, this is probably representative of a time when the only light pollution to worry about was that of candlelight :shock:
I envy those guys!
