I recently bought a basic set of Orion planetary filters. Viewing
Jupiter with the filters made no difference. The viewing conditions
have been below average, but the view of Jupiter was clear.
Does the Great Red Spot have to be in transit for the planetary
filters to be useful?

Well last night I used the Orion 80A blue filter from the stargazer's set.
It did make one equitorial band darker and easier to see.
