209552 Isaacroberts           Discovered 2004 Nov. 9 by the Faulkes Telescope Educational Project at Haleakala.
Isaac Roberts (1829-1904) is best known for his pioneering work in astrophotography. He was a prominent engineer by profession, but as an amateur astronomer advanced the idea of using long exposures to reveal detail that would not normally be visible to the human eye.
