242830 Richardwessling           Discovered 2006 Feb. 21 by R. Holmes at the Astronomical Research Institute, Charleston.
Richard J. Wessling (b. 1935) worked at U.S. Precision Lens for 35 years, making telescope mirrors from the early 1960s onwards and opening the Pines Optical Shop in 1991. Richard made hundreds of telescope mirrors and built dozens of telescopes that can be found in the hands of astronomers throughout the United States.
