Using a FITS viewer (such as ds9) on the new-image.fits file available for downloading from that page, you can read off (ra,dec) directly by putting the mouse cursor over any part of the image.
The matching is quite good:

Can see the spurious detections on this check image, but the genuine ones are right on the money. Green is a detected source from your photo; red is a catalog object.
Cheers,

Hi Greg,
astrometry.net succeeds on this image, but it took some time---I think it was almost faked out by spurious detections of "stars" detected within the mast. Here is a link to the results of their web service on this image:http://nova.astrometry.net/user_images/72641#annotated
