Corwin's Notes

===== NGC 7148 is a triple star. (I had originally called it a double, but the SDSS shows the northeastern of the pair to be a close double star.) Observed three times on two nights by d'A, its identity is pinned down not only by d'A's accurate absolute position, but also by his relative position to NGC 7149 just 2.5 arcmin to the south. N7149 was observed the same three times on the same two nights, so there is no mistaking the identity of N7148 as anything but the double star. LEDA has nevertheless incorrectly taken a double galaxy, much too faint for d'A to have seen with his 11-inch telescope, as NGC 7148. The galaxies are also well off the mean of d'A's three accordant positions. Tsk. There is also a very faint galaxy just south of the double. At V = 17.7, it is well below d'A's visual threshold with his telescope, so plays no role in the visibility of the NGC object.
