    SkyMap by Rob Matson has constraints on magnitude, elevation, culmination,
    perigee and range (not MM). Magnitude limit can be set to 50! You can edit
    HORIZONS' latitude, longitude, range (above Earth's surface) into a "rocket
    trajectory" (.trj) file to avoid plotting manually, and produce many plots
    in different scale/center/coordinate grid/time tag spacing.
