I did what I mentioned in the prior post, and astrometry.net solved it with index file 4109.fits
This file is not located in their regular downloads or through the ansvr index downloader.
If you go to the main astrometry.net download page there is a link to for "Wide field" images.
Currently: http://broiler.astrometry.net/~dstn/4100/
If you download the 4109.fits and put it in your index directory: %appdata%\Local\cygwin_ansvr\usr\share\astrometry\data
(move the current *.FIT index files out of there for a test) and see if it works out.
