Re: [Utah-astronomy] Saturn

I noticed Saturday night that the banding on Saturn was made much more visible when I used a pale-blue filter; contrast was enhanced as well. The filter is so mild that a color shift was not noticed. The crepe ring's visibility was not reduced. A couple of Mars oppositions ago, I noticed a similar effect, with a somewhat denser blue filter. Even with the filter, Mars was so red to begin with, that the filtered view was almost "natural", with contrast much enhanced to boot. Anybody else using filters for planetary viewing?
