The #80A Medium Blue Filter is one of the most commonly used filters amongst the entire spectrum of filters. It is perhaps the best filter for the study of detail on Jupiter and Saturn. It enhances the contrast of rills and festoons in Jupiter's cloud belts, as well as details of the Great Red Spot. It brings out detail in Saturn's belts and polar features. The filter is very useful on Mars in showing the high clouds and ice caps, and is especially useful during the violet clearing.
