Markree Observatory

[1][2][3] The asteroid 9 Metis was discovered from this observatory in 1848 by Cooper's assistant Andrew Graham using a comet seeker telescope.

[5] In the later 1800s it was operated again after a brief hiatus, and gained note for its meteorological observations and research on double stars.

[5] In 1830, Colonel Edward Joshua Cooper MP (1798–1863) eldest son of Edward Synge Cooper MP, and Ann, daughter of Henry Vansittart, Governor of Bengal, set up Markree Observatory on the grounds of Markree Castle near Collooney in County Sligo.

(Royal Astronomical Society, 1851)[9] In 1848, Cooper's assistant, Andrew Graham, discovered the asteroid 9 Metis with a wide-field comet seeker telescope manufactured by Ertel.

Pierre-Louis Guinand (de fr) (20 April 1748, La Sagne — 13 February 1824, Les Brenets[12][13][14][15][16][17]) was a Swiss[18][19][20][21][22] who in the late 1700s came up with a breakthrough for making better quality and larger glass, and in time went on to teach a young Fraunhofer at Joseph von Utzschneider's (1763-1840[23]) glassworks, and eventually started his own optical glass works.
