ASTRONOMY] HERSCHEL, JOHN FREDERICK WILLIAM [Sir] A sammelband of three separately published offprints of Herschel's observations with his twenty-foot reflector, including Account of the observations made with a twenty-feet reflecting telescope. London: Richard Taylor 1826; Account of the observations made with a twenty-feet reflecting telescope containing, a second catalogue of 295 new double and triple stars... London: Richard Taylor 1827; Fourth series of observations made with a twenty-feet reflector containing the places, descriptions, and measures of 1236 double stars... London: J. Moyes, 1830; and three further substantial works by Herschel on double stars and nebulae, probably extracted from the Memoirs of the Astronomical Society. 19th century three-quarters calf. 10 3/4 x 8 1/2 inches (27.5 x 21 cm), various paginations, three lithographic plates in the first work. Front cover and spine almost detached, generally clean. Extensive notes on the endpapers and in the margins by the astronomer Wentworth Erck (1827-1891), who had a fine observatory with a seven-inch Clark refractor and a fifteen-inch reflector in County Wicklow. An interesting selection of Herschel's papers, largely on binary stars and nebulae, which saw serious use with an astronomer in the latter half of the 19th century, who has appended many interesting notes, some critical of Herschel.
