Yup.

Hmmm... try clicking on Extras... Toggle User Datasets, then
on "UCAC-3". Make sure that it's turned On, and you may want to
turn on labels as well. Also, look at the "show at" fields and
make sure they cover the fields of view you have in mind. (Be
warned that you _could_ have UCAC-3 shown at fields of zero to
180 degrees, but it'll take a while when you get near the latter.)

If you don't even see the "UCAC-3" option, or if the stars
still don't show up, please let me know.
