Quick question about negative declinations

  1. I am trying to find the sky position of asteroids so that I can observe them using a telescope.
    This site quotes the declination angle in hours and appears to range from 0 to -24. I have never heard of a declination angle more negative than -12 hours.
    What does this mean?

    thats incorrect

    RA = Right Ascention is in hours minutes and seconds 0 - 24Hrs

    DEC = Declination is in degrees minutes and seconds 0 deg at celestial equator going to + and - 90 degrees
