Double Stars

I have added a page of multiple stars at http://astro.aule-browser.com/stars/binary.html

It is basically the txt file  ftp://nic.funet.fi/pub/astro/dbases/stars/multistr.txt  but with some improved encoding.  This is just a first pass: they intended the file to be pulled into a database.

There are also a number of relevant links on the page.

Note: the list is for the northern hemisphere and is sorted by constellation.

More useful might be a page to extract a list of binaries whose DEC is within 10 degrees of your latitude for viewing near azimuth - not to mention selection by within 2 hour angles.

The simple Rebol 278 code used to extract the file is given at the bottom of the web page.
