...
Or not... it appears that I cannot upload a file bigger than about 500kB so I cannot upload the 3.8MB compressed Hipparcos catalog. Sorry, I tried.
Our four test images are:
* 56717.2500116
* 56717.5972338
* ut030114.0170
* ut030114.0650
Let's if the procedure above works on one of Chris' images, and if so
let's bundle it into a script. The input to the script will either be
HA, Dec, Az, scale or else a bootstrap file of x,y,RA,Dec.
I presume these images were taken at LCO: -70.6926, -29.0146, 2380.
Nope, actually Cerro Pachon, -70.7336, -30.2379, 2647
(-70 44 01.11, -30 14 16.41).
Stomp around ut030114.0170 with monsta and ID some stars:

and ut030114.0650 (this is way overkill, but I'm adding some named stars):

Let's try it out! Although I don't particularly like nested scripts,
let's bundle fishiter.sh into yet another script, called fishy.sh.
{{{
fishy.sh ut030114.0170.fits LNG=-70.7336 LAT=-30.2379 BOOT=ut030114.0170.id
fishy.sh ut030114.0170.fits LNG=-70.7336 LAT=-30.2379 HA=0 DEC=-28 AZ=94 SCALE=0.046

fishy.sh ut030114.0650.fits LNG=-70.7336 LAT=-30.2379 HA=0 DEC=-28 AZ=94 SCALE=0.046

This seems to work OK.
Can I get the other two to work using the known pointing?

Yes, it works, but it's crucial to get the scale accurate to at least 1%.
