Thanks, Renato. I have been looking at the Orion 5562 2-Inch Variable Polarizing Filter which does exactly what you say. I do have a ND Filter so I might just try that before I get the polarising filter.
One thing I know - I won't try looking at 16th magnitude stars just after I have looked at the Moon!
Kind regards
Stephen
