If you want to solve your images on line (while you are observing)  then
PinPoint will do the job.  You don't need a full license to do this
using MaxIm. Once you solve the image, then you can sync to the center
of the image from MaxIm telescope control.  MaxIm's Astrometric
Synchronization also makes like much easier for TS.  MaxIm uses PinPoint
to solve every Nth image (you specify N) and recenters the scope.

PinPoint needs a decent number of stars (say 7?) to get a good solution.
So if you have a small FOV, PinPoint may have problems solving the
image.  Also when the seeing gets bad (greater than 4" FWHM for my
setup) all bets are off with PinPoint.

I believe that there will be  MaxIm and ACP workshops the day before the
SAS conference starts.  You should be able to get lots of good info
regarding MaxIm and PinPoint at the workshop(s)

Meridian flips aren't really that bad, they just seem that way.  I have
two Losmandy C11's with two different goto systems on them (SkyWalker
and Gemini).  Both will let me establish the safety point at which I
want the mount to flip.  So I can go well beyond the Meridian so long as
I'm not beating the camera against the pier.

A Paramount will always make life easier if you are willing to write the
check ;>}...or maybe an AP.
