This SAOimage display shows only the test image, but you can still identify stars in the image, since it has a world coordinate system. immatch can be run to list matches between USNO-SA1.0 stars and sources found in the image. The command used to display the image, before the [ and ] keys turned off the catalog plotting, was 

saousa1 test.fts
where saousa1 is 
saoimage -reg `imusa1 -r 10 $1` -wcscom susa1_-ha_%s $*
