This 2-inch blue color filter from Omegon is a popular tool for seeing more details while observing the giant planets. The filter increases contrast in Jupiter’s cloud bands and storm regions, makes structures in Saturn’s atmosphere more visible, and helps to better distinguish polar caps and dust formations on Mars. On the moon, this filter enhances details along the terminator, where light and shadow meet.
The glass is fully colored and mounted in a sturdy anodized aluminum housing only 5 mm thick. Thanks to this slim design, the filter can also be used seamlessly in filter wheels and zenith mirrors. The double filter thread makes it possible to combine multiple filters. The filter comes in a sturdy storage box for protection.
