Named in honor of David F. Malin, chemist and astrophotographer at the Anglo-Australian Observatory. He has developed new methods of extracting information from astronomical plates, an enhancement technique that has led to the discovery of extremely faint but large-scale features associated with otherwise normal galaxies. His special photographic and developing procedures have brought him worldwide recognition and acclaim. The discoverer has long been an admirer of his innovative photographic methods, which produce extraordinary photographs of celestial subjects in glorious color and detail. Malin is a well-known lecturer on his photographic techniques and has written many scientific papers and books on the subject. (M 18646) _ _.
