Howdy. Please ask your questions and post your experiences about:
- the Astrometry.net web service (
http://nova.astrometry.net)
- the command-line code (
http://astrometry.net/
downloads/
)
- the Flickr group Astrometry (
http://www.flickr.com/groups/
astrometry/
)
When reporting a bug, please include the URL to your web submission, or an example image showing the problem. This makes it much easier to track down.
thanks,
dustin
