I removed 8 significant star dots from the chart because they are galaxes.
New chart on way soon, but I think Aaron is out, so I don't know who to send
it to for release.  SRB

Nova in Cet - ChartError

>>  My A2 and GSC catalogues, and the DSS, show a mag 10 galaxy at that

     Remember that the Schmidt plate-scan catalogues are rigged to
get magnitudes for stars, and for extended objects like galaxies the
values are several magnitudes too bright.
     This galaxy is, however, small enough to show reliable results
from ASAS, which shows V=13.8.  This is consistent with total V
inferred from the existing near-IR photometry in NED, where
total J ~11.5, and typical V-J color for a galaxy is "about 2".
