Rearranging comments in Drupal

Moving comments around in Drupal is not (yet) straightforward. There is an experimental module that aims at providing this type of funcitonality, but the maintainers strongly discourage you in using it on live sites. If you're a daredevil, just go ahead and play with the comments table. You might ruin your comment structure though… unless you want to understand how Drupal manages comments. After reading this post you should be able to move comments without fear.

Herald-Bobroff chart references for the SAC database of deep-sky objects

The Saguaro Astronomy Club (SAC) Database is the result of more than 20 years of devotion to create and maintain a list of more than 10,000 worthwile deep-sky objects within reach of many amateur astronomers. The database is managed by Steve Coe and has a historic data format. It contains lots of information about these objects, such as the object type, celestial coordinates (RA and Dec), brightness, position angle etc. but also links to charts in the first release of Uranometria 2000.0 and in the Tirion Sky Atlas 2000.0.
