IC 5098 is probably the double star I've listed in the position table. See the discussion for I5097 for the reasons I take this double rather than some of the other stars nearer Bigourdan's nominal position.

He gave the estimated position for this object only in the description for IC 5097 -- it is at position angle = 100 degrees, distance 2.5 arcmin from NGC 7045. With such a crude estimate, we have considerable latitude in choosing which star Bigourdan might have seen. So, this identification is also uncertain.

Looking at this again in November 2015, I'm even less certain about the identification than I was earlier. The pair is relatively widely separated (about 12 arcseconds), so perhaps just the brighter star is the one that Bigourdan saw. But this, too, is a guess, so I've simply changed my earlier colons to question marks.
