Astrometry.net has built this astrometric calibration service to create correct, standards-compliant astrometric meta-data for every useful astronomical image ever taken, past and future, in any state of archival disarray. They hope this will help organize, annotate and make searchable all the world's astronomical information. (Source Astrometry.net)

I did some more testing and each time feedback was in short matter of time given of the details of the picture.
