An obvious WIBNI: add an option to solve-field et al.

--xscale scalefactor

where scalefactor is either 8.6x8.3 or 1.036 for the image in question. Detecting either form should be easy enough (does it contain 'x').

Okay, that fixes it --
I trimmed the bottom off, and then scaled it horizontally by 1.036
(fitstopnm 1.fits | pnmscale -xscale 1.036 | ppmtopgm | pnmtofits > 2.fits)
 
And I get this solution:
