8294 Takayuki           Discovered 1992 Oct. 26 by K. Endate and K. Watanabe at Kitami.
Named in honor of Takayuki Kawabata (b. 1959), president of astronomy shop Planet Town, Kumamoto, Kyushu Island. An active amateur astronomer and an avid fan of CCD imaging and image processing techniques, he is well respected for both his varied image library and his ability to find astronomical details usually unseen by others. Name proposed by the discoverers following a suggestion by Y. Yamada.
