If you're a newcomer, you could ask yourself: and now what I have to do?
Ok, don't panic. First, click on the Database
tab and look at the left vertical bar: I prepared ready-to-use double star selections for you.
Just click on the names, for example the most populars doubles
list or the three stars systems
Next, I suggest to register yourself
choosing a username and password: once you're logged in, use the Setup tab to setup your site's preferences.
Remember to input your telescope's diameter (aperture): by means of the Dawes formula I can calculate the minimum separation between two stars permitted by your instrument, so you can filter out doubles too close to be seen.

StelleDoppie version 2.6
[upd] a new layout adapts tables to windows size, or more space for data
[upd] orbits are now displayed as blue dots, not connected with lines.
There's a serius problem with trigonometric functions precision in the language.
I gave up. This may not be the best display solution but avoid the
"spaghetti orbits" effect (i.e. Zet Boo)
[new] added a popup on the right column to change list format on the fly. This is the
same found in Setup->Preferences->List Type, but I felt uncomfortable to play with.
I recall you can create you own custom columns list if you login.
[fix] Excel export was not ordered as the list shown
[fix] some GAIA codes where interpreted as numbers when exporting to Excel, rounded (!)
[fix] ordering by modification date (date_mod) did not worked properly
[fix] some minor issues fixed
[upd] WDS and all related databases are now updated to the latest version.
