IC 4668 is a star. It was a bit difficult to track down since Bigourdan mistakenly swapped its comparison star for the comparison star for NGC 6474 (which see for a different story). When the correct star is used, Bigourdan's position is an even 10 arcsec off, suggesting another error. However, I've not checked closely for that one. The position is close enough.
