    I composed VISUAL.TLE/VISIBLE.TLE to contain just such satellites.
    The file was on Celestrak and Mike's sites. Unfortunately, I haven't been
    able to update those files recently, but you may use them as a base for your
    own list. Mike did update the list on his site.
    mccants.tle was a much larger list containing interesting sats that were not
    necessarily of naked eye brightness.
    The visible list at Space-Track is far less accurate.
