    Default Dumb Question about SAO



    What does "SAO" stand for?

    I understand that every/some/most/a lot of stars have SAO numbers.

    Do SAO numbers apply only to stars?

    Is there a catalog that cross-references SAO numbers to named stars and
    vice-versa -- so, if I want to see Eps Lyrae in my GOTO, I can access the
    SAO menu and tell it to GOTO SAO 12345?

    Thanks.

    Smithsonian Astrophysical Observatory Star Catalog.


    Down to about 9th magnitude, yes.


    Yes.


    Down to about 5th magnitude in my book, Celestial Objects for Modern
    Telescopes. A more thorough one is available from the Astronomical Data
    Center (it's the work of W. Barry Smith; you should be able to find it via
    Google).

    Actually, it bothers me that computerized telescopes do not let you enter
    Bayer or Flamsteed designations (Alpha Centauri, 61 Cygni, etc.). They
    ought to. Instead the telescope people seem to enjoy digging up "names"
    that have been out of use for centuries.

    My book gives information about all the widely used catalogues and systems
    of nomenclature.

    SAO - Smithsonian Astrophysical Observatory Star Catalog


    A quick search on Jeeves found this
    http://www.ledas.ac.uk/arnieV4/indhelp/indhelp_sao.html

    <extract>
    Overview
    This database is based on the electronic version of the SAO catalog from
    the Astronomical Data Center, which is itself based on an original
    binary version of the Smithsonian Astrophysical Observatory Star Catalog
    (SAO, SAO Staff 1966). Subsequent improvements by T. A. Nagy (1979)
    included the addition of cross-identifications from the Table of
    Correspondences SAO/HD/DM/GC (Morin 1973). As a prelude to creation of
    the 1984 version of the SAO, a new version of the SAO-HD-GC-DM Cross
    Index was prepared (Roman, Warren, and Schofield 1983). The 1984 version
    of the SAO contained the corrected and extended cross identifications,
    all errata published up to January 1984 and known to the ADC, numerous
    errors forwarded to the ADC by colleagues, and errors discovered at the
    ADC during the course of this work. Clayton A. Smith of the U. S. Naval
    Observatory provided J2000.0 positions and proper motions for the SAO
    stars. Published and unpublished errors discovered in the previous
    version (1984) have been corrected (up to May 1991).

    Which GOTO scope do you have? The Nexstar i-series (and I think GPS)
    scopes have ~29,000 SAO stars but it's a real pain to use that list in

    It stands for "Sold Astronomical Objects."

    These are astronomical objects which have been sold through the
    International Star Registry. Since the purchasers have an official
    laser-printer certificate, and the names have been published in a book that
    is registered with the library of Congress, these names are now official,
    and must be used by astronomers. Of course, astronomers are jealous that
    they didn't think of it first. Therefore astronomers have resisted using the
    names. In a passive-aggressive move, they have refused to use the full
    names, and are using only the numbers. The numbers were assigned in the
    order of purchase. However congress is now drafting legislation that will
    force astronomers to use the full names. This is only right, as these people
    paid good money, and have official certificates.

    Of course, as an officially published book, the names are protected by
    International Copyright, thereby forcing the rest of the world to at least
    use the numbers as well. And, as more copies of the book are registered with
    governments around the world, eventually astronomers everywhere will have to
    acknowledge the officialness of these names and use the full names and not
    just the Sold Astronomical Objects numbers.

    ("It must be official. I have an official laser-printer certificate!")

    Given a first shot I would have done pretty much the same.
