7465 Munkanber           Discovered 1989 Oct. 31 by B. G. W. Manning at Stakenbridge.
Named in honor of John Munger, Veikko Kanto and Richard Berry, the authors of The CCD Cookbook. By providing detailed instructions and software, they have made it possible for the amateur astronomer to construct and operate an efficient, low-cost CCD camera. The final imaging and astrometry of this minor planet was carried out with such a camera made by the discoverer.
