Recommended applications for this filter:
Mercury – May improve observations of rarely visible faint surface features with scopes 8" to 10" in aperture and larger. Venus – Increases contrast of occasional faint dark shadings in the upper cloud deck. Mars – Useful for detecting high clouds and haze over the polar caps with large scopes, particularly during the still-unexplained phenomenon of violet clearing (when the Martian atmosphere – normally a bright, featureless disc in violet light due to the scattering of short wavelengths of light by the thin atmosphere – becomes transparent through a violet or blue filter, revealing large dark surface features). Jupiter – Primarily used for enhancing the boundaries between the reddish belts and adjacent bright zones in the upper atmosphere . Helpful in defining the Great Red Spot and festoons in the belts with scopes 8" and larger. Saturn – Good for enhancing the ring structure with 8" or larger scopes. Comets – Useful for observing brighter comets with scopes 10" and larger.
