    I'm not sure what you mean: the object is detected, its brightness measured, and its magnitude is calculated.

    Do you mean spectral classes?

    Also, remember the difference between absolute and apparent magnitude, which describe the object's magnitude from 10 parsecs and from a chosen distance, respectivly.
