soundboard decorated with classical arabesques. The music room also contains a modern sculpture of an orrery, created in 2009 and based on the 18th Century Brass Drum orrery held at the museum. Collections The museum holds a small dress worn by Caroline when she was around 50. It is made from white muslin with a blue spot and dates from the last years of the 18th century. The museum also has a Thomas Butterfield sundial, dating from c.1690, made of silver in the shape of a bird, with names of European cities and their latitudes on the back; a Copernican Armillary sphere by George Delamarche, made of brass, wood and paper, and with Herschel's name and Uranus on one outer ring; a Cometarium showing the motion of a comet on its path around the sun, on loan from the Science Museum; and paintings of Elizabeth Baldwin by Robert Muller (pre-1798) and John Herschel (1892). A scale model of the 40-foot telescope, as well as an early photo of it that is framed in wood from the telescope, is on display at the museum. Additionally, several rare books, including Caroline's visitor book, can be viewed on a computer. In 2015 it was announced that the museum will house Patrick Moore's collection of objects related to William Herschel.
