Wilhelm Struve found 13 NGC objectsin 1825 while searching for double stars with the 9.6" f/17.8 Fraunhofer refractor at Dorpat (installed 1824); 6 were new. All objects are contained in: Struve, W., Catalogus novus generalis stellarum duplicium et multiplicium, Dorpat 1827. The objects numbered 1 to 9 are listed in the appendix (Nebulae detectae), the other ones in the main catalogue (as double/multiple stars and desginated with S). Two objects (NGC 629, NGC 6648) are also contained as #16 and #41, respectively, in Auwers, William Herschel's Verzeichnisse von Nebelflecken und Sternhaufen, Königsberg 1862.
