For visual purposes, coloured filters are the standard planetary observing aides.
However, for photography, you don't want a clour-cast
So.....

Try a contrast-booster to bring out subtle shading details
Baader 'Neodymium' does a good job, at a reasonable price.

What tecnique do you plan to use?
I find best results come from taking an avi movie, then use stacking software (Registax is good - and FREE)
Try to get a good few hundred frames - and when starting Registax, use the sharpest frame you can find as your reference frame, then set it to only stack frames of at least 90% the quality of the reference.

At the 'wavelet' stage, I find using the second slider only, gives best results..
And don't overdo the wavelet sharpening - too much will make it look fake, or at least 'overprocessed'.
Less is more........
