     For such cases in the future, it would seem preferable
to take exposures of just 1- or 2-seconds, rather than 60s.
You need only a handful of reference stars for the astrometry,
and thus a minimal exposure in hopes of not totally overexposing
the target.
     Preferred coordinates of the mag ~15 progenitor are:
13 54 45.35 -59 09 04.1  (UCAC2)
13 54 45.35 -59 09 04.1  (2MASS)

     Assuming this identification is correct, I note there
is an XMM x-ray source only 2" away.  Such a detection might
not be unexpected for a close binary leading to a classical nova.
