Auwers discovered two NGC objects: NGC 4402 and NGC 6503; see his William Herschel's Verzeichnisse von Nebelflecken und Sternhaufen, Königsberg 1862. NGC 6503 (#37 in his list of new nebulae) was found on July 22, 1854 when he was still a pupil in Göttingen, owning a 2.6" Fraunhofer refractor. He showed his friend Winnecke, than studying at Göttingen University, the new object (see Winnecke's report in AN 45, 247 (1857)). NGC 6503 is a galaxy in Draco. The second object, NGC 4402 (#30), a galaxy in Virgo, was found on March 5, 1862 with the 6.2" Fraunhofer heliometer at Königsberg Observatory.
