Lowe at RAS Observatory, Mayhill. Robert Hutsebaut (b. 1941) is a Belgian amateur astronomer with a particular interest in minor planets. He has used the remote facilities at Rent-a-Scope Observatory to confirm many near-earth objects, in addition to discovering a number of main-belt minor planets.
