The Sirius Optics PC1 is relatively bright (even with a 4 inch scope) and does what it says it will on the Jupiter, Saturn and (surprisingly...) Mars. The effect is not dramatic but is demonstrable.
The first two planets to sample were Jupiter and Saturn. Saturn gave more brownish and yellowish line structures on the globe of the planet. The Polar region was better to see. Shadows on the globe and on the ring behind the planet gave a better look. But the Cassini Division was NOT sharper. Also Jupiter gave more details on the globe. Structures in the equatorial bands were easier to see. Great Red Spot was also easier to find as a hole in the band. \
But for the most part.... the Planetary Contrast filter gave an allround better picture than without a filter. Darker and lighter features were easily seen. It worked also on the red planet. And if your big scope collects too much light, combine it with a variable polarizing filter
