Alpine Astronomical FCFO-2 overview

  • 1Description

Centered on the 570nm wavelength, the Alpine Astronomical Baader Orange Colored Bandpass Eyepiece Filter can be used by itself or stacked with other filters to enhance your observations when viewing planets such as Mars, Jupiter, and Saturn or during daytime viewing of the moon, Mercury, and Venus. 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
  • Enhances contrast of lunar and planetary observations at dusk
  • Improves the detection of dark areas on Mars and penetrates the hazy Martian atmosphere
  • Reveals detail in the cloud bands of Jupiter and Saturn
  • Well suited for daytime observations of the Moon, Mercury, and Venus
  • 98% average transmission bandpass throughput
