IC 717 = NGC 3779, which also see. Frank Muller observed this and NGC 3775 before the NGC was published, so the "name" he assigns to NGC 3775 is the reference to Common's short list of new nebulae in Copernicus. He also used NGC 3775 as the reference "star" for his observation of this. Given that he knew about Common's list, I find it a little odd that he labels this galaxy a "Nova" in his list.
Unfortunately, Muller measured only an RA for the galaxy, and that is exactly 30 seconds of time too large. His offset from NGC 3775 is printed as +0min 53.92sec. Since he measured this three times, I suspect this is a simple transcription or typographical error somewhere between his observing log and the published table.
Whatever happened, Muller's description leaves no doubt that he saw NGC 3779. He called it magnitude 15.8, diameter 1.0 x 0.8 arcmin, extended 90 degrees, diffuse. This is perfect for this low surface brightness object, so the identity with NGC 3779 is certain.― IC Notes by Harold Corwin
