9110 records from the Bright Star Catalogue - Harvard Revised (HR) catalog
194 common star names
279 double star reports (256 distinct doubles)
420 measured
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 list
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.
Have fun!
