This light red color filter from Omegon in 1.25 inch format is ideal for observing Mars and other planets where high contrast is desired. The red color makes subtle structures more visible, such as polar caps, dust storms, and dark areas on the Martian surface. The filter can also be used for visual observation of the moon at low altitude or when moonlight is bright.
The filter cell is made of precisely machined anodized aluminum. With its very thin profile, this cell prevents shadow formation and diffraction. The glass is fully homogeneous and multi-coated to ensure clear and high-contrast image quality. Thanks to its double threading, the filter can be combined with other filters. The filter comes in a sturdy protective case.
