It also brings out the red and blue regions such as the Great Red Spot on Jupiter in contrast to the lighter portions. It is useful for observing the low-contrast hues of blue and red in the Jovian atmosphere. The filter enhances Saturn's cloud belts and polar regions and increases contrast of cloud patterns on Venus. This filter is good for lunar observing as well. The filter may not yield good results on small telescopes.
