Centered on the 435nm wavelength, the Alpine Astronomical Baader Dark Blue Colored Bandpass Eyepiece Filter can be used by itself or stacked with other filters to enhance your observations when viewing or imaging planets such as Venus, Mars, Jupiter, and Saturn. The optical glass filter is planeoptically polished and treated with seven-layer Phantom Group anti-reflection multi-coatings to improve contrast and clarity while eliminating reflections, scattering, or image dimming. Holding the filter is an black anodized aluminum frame made to fit standard 2" eyepieces and other accessories such as diagonals and Barlows.

Use

For visual and photographic planetary use

Aids in better detection of Venus phase

Improves view of the Violet Clearing on Mars

Enhances the Great Red Spot on Jupiter and contrast between the belts
