IC 229. A nebula is marked on the CD chart, and Dreyer read its position correctly from the chart -- but it does not, in fact, exist. Since Thome was observing with a small telescope (12.5 cm), it is unlikely that he saw and incorrectly recorded any of the fainter galaxies in the area. Unlike the other four "nebulae" found by Thome (IC 1023, 1203, 1207, and 1290), this one is not an asterism, either. The nebula is not on the 1929 edition of the CD charts, so may have been an error affecting only the first edition.

Courtney Seligman ( http://cseligman.com/text/atlas/ic2.htm#ic229 ) has suggested that Thome's object is the 12th magnitude star an arcminute south of CD -24 1093. See Seligman's discussion for more detail. I've put the star in the position table as a possible identification for IC 229.
