IC 3666 is a star. Schwassmann has the description as "eF, vS, ?, α:, δ:". The lonely question mark is interesting -- Dreyer even copied it verbatim into the second IC. It, and the colons on the position symbols, show that Schwassmann was not particularly confident about this object.

However, the star is there on the DSS, so Schwassmann's plate did record something at his position. There may also have been a defect or a bit of random grain noise that lent a bit of fuzziness to the image, too.
