Welcome! Please ask your questions and post your experiences about Astrometry.net:

- the Astrometry.net web service (https://nova.astrometry.net)
- the command-line code (https://astrometry.net/downloads/)
- the Flickr group Astrometry (https://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.

The group is (temporarily, I hope) set so that you have to ask permission to join & post, because we've had a bunch of spam postings. All real humans are accepted!
