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
