    Default Friedrich Struve catalog of double stars - primary source :)



    Have you ever stumble on double stars labeled with STF or "sigma" sign followed by numbers, looking through star maps or on-line resources? They were cataloged by Friedrich Georg Wilhelm von Struve in XIX century.

    Many of them are popular targets for double star splitters and included in various on-line databases or printed atlases. Many, but not all . For some shown in Interstellarum Deep Sky Atlas I could not find any info in books or on-line. So I figure out why not go for the primary source?

    Behold

    Catalogus novus stellarum duplicium published in 1824.

    https://books.google.com/books?id=sP...page&q&f=false

    Info is split to several tables, but you can find RA/DEC, magnitudes and separation. My Latin is rudimentary, but I had fun looking through pages.

    Just a reminder, however, that I doubt he was using our most recent epoch so the RA and DEC may be a little off in some cases.

    But it is an old and respected catalog!
