GSO 2" Astro Filter #21 | Orange
This filter really helps with enhancing lunar features.
The brightness of the daytime sky is reduced significantly, so is useful for observing both Mercury and Venus during the daytime, especially for revealing surface features on Mercury.
Used on Mars, it enhances the boundaries of dark surface features.
Both Jupiter and Saturn benefit by increasing the contrast between their dark belts and bright zones. Jupiter’s great red spot also pops into view using this filter.
Used on bright comets in larger telescopes it enhances the definition of the coma and any dust tail.
