To follow-up on identifying the star I had located near the center of NGC3521,
I took a 60s exposure last night. Using Bob Denny's excellent Visual PinPoint,
I determined the coordinates to be 11 05 50.50, -00 02 48 (2000) with a visual
magnitude of 17.7 (r). Supplying the coordinates to the DSS2 IR 2nd Digitized
Sky Survey-Near Infrared (on the left) showed the star as you see it circled in
the 60s photo on the right.
Thanks, Brian, et al, for turning me onto this terrific tool (Skyview).

Tonight, I'll shoot a FITS image with TSXPro's capture program (Camera Add-On),
which will enable me to do a real image-link and pinpoint the location of the
suspect star and use it's coordinates in the SkyView utility. Will report back
tomorrow.
Thanks very much for this Brian. This will extend my reach and understanding.
Bill
ps: Thanks, Albert.

In general the usual star (or "object") catalogues
will _not_ show things very well resolved inside
galaxies, especially near their centers. So recourse
will usually have to be made to modern survey images
like the Sloan Digital Sky Survey, 2MASS, etc.
Many of these can be freely accessed using the
Goddard SkyView utility:
http://skyview.gsfc.nasa.gov/current/cgi/query.pl
...where one can select images from across the
entire electromagnetic spectrum.
