Andre,
I had the best luck with two linear polarizers which acted like a variable neutral density filter. One polarizer is attached to the objective lens while the other is held in the fingers. The camera was operated in manual mode at 1/4000 sec, f22, ISO 100, infinite focus. The 200 mm fixed focal length lens was hand held. Several images are captured in sequence as the linear polarizer is rotated in the fingers. The best image is then selected. For some reason the linear polarizers looked better than the circular polarizers. I tried various combinations of linear and circular polarizers to see which combo delivered the best image. The linear polarizers were also better than the solar film at high shutter speed.
