Filters for Bright Object viewing.

I've just recently bought a 150 reflector and while its great on most objects, when looking at Jupiter the planet is so bright I can't pick out as much detail as I used with my old 60mm. I have some coloured filters, Blue, Green, Red, Orange and 15/30% moon filters, but none of them seems to make a lot of difference. Can anyone suggest a filter which would be suitable for bright planet viewing.

Two polarising filters. You can adjust light transmission by rotating the bottom one relative to the top one. You can reach a point at which almost no light is transmitted.

AOE will sell you a pair of 1.25" for $25.

At that price, it's worth a try if you really are struggling with brightness. I've a pair, and done a quick check to see that they will darken the light sufficiently, which they do. Haven't spent the time to see the impact on surface detail.

Try attaching the blue filter to one of your moon filters.
Maybe the 15% one first.
