Albert Marth discovered NGC 6945 = m 420 = St I-10 on 12 Jul 1864 and noted "vF, vS, R, stellar or neb. *." Édouard Stephan independently rediscovered the galaxy (though Marth's position was good) on 1 Jul 1870. Stephan's micrometric position is very accurate.

400/500mm - 17.5" (7/16/88): moderately bright, small, round, bright core, stellar nucleus. A mag 15 star is 28" SW of center. Located 2.9' SW of bright mag 6.6 SAO 144663.
