         Give comets about 20 min between exposures. Expect motions on the
    order of a few tens or less arc seconds/sec of motion unless they are
    near Earth objects. With the asteroid surveys going these days, it's
    hard to discover a comet with a V mag less than 18 before the
    professionals get it.
    
          Use the Minor Planet MP Checker service to verify your object was
    already not discovered at ....
