ansvr - local astrometry.net plate solver
The ansvr bundle allows Sequence Generator Pro users to run the
Astrometry.net plate solver on their PC
in place of the nova.astrometry.net Web service. This allows SGP users
to access the Astrometry.net plate solver without an internet
Although ansvr was originally written for SGP, several other applications are now
using ansvr as a convenient way to run the Astrometry.net plate
solving engine on the local Windows PC. If you are
or another application that can make use of ansvr, please
follow the installation instuctions below, but simply stop at the
point where the instuctions start talking about configuring SGP. At that point you have a fully functioning ansvr / Local Astrometry.net installation and you can proceed to setup your application to use it.
The installer is fully self-contained; there are no prerequisites for
installing any other packages.

Windows XP Compatibility
The most recent version of ansvr is based on a version of cygwin that is not compatible with Windows XP. You can still use ansvr on Windows XP by running an older version of the installer
