Guide Star Catalog

The Guide Star Catalog (GSC) is also known as the Hubble Space Telescope, Guide Catalog (HSTGC). It is a star catalog compiled to support the Hubble Space Telescope with targeting off-axis stars. GSC-I contained approximately 20,000,000 stars with apparent magnitudes of 6 to 15. GSC-II contains 945,592,683 stars out to magnitude 21. As far as possible, binary stars and non-stellar objects have been excluded or flagged as not meeting the requirements of Fine Guidance Sensors. This is the first full sky star catalog created specifically for navigation in outer space.

Famous quotes containing the words guide and/or star:

    With my desire to write he seemed in full sympathy, and in urging our early marriage he argued that my first necessity was leisure in which to develop and to master my craft. It appeared to me that with such a man as teacher and guide I could not fail, and it was in a queer mixture of young love and vaulting ambition that I became a wife.
    Rheta Childe Dorr (1866–1948)

    Well gentlemen, this is it. This is what we’ve been waiting for. Tonight your target is Tokyo. And you’re gonna play ‘em the Star Spangled Banner with two-ton bombs. All you’ve got to do is to remember what you’ve learned and follow your squadron leaders. They’ll get you in, and they’ll get you out. Any questions? All right that’s all. Good luck to you. Give ‘em hell.
    Dudley Nichols (1895–1960)
