Be the first to review this product

The Saxon Colour Planetary Filter No. 21 - 1.25" is an orange astronomy filter that reduces transmission of blue and green wavelengths, thus increasing the contrast between these areas and red or yellow or orange areas. This is ideal for Mars viewing as it will help sharpen the boundaries between these areas on the planet's surface. It can also be used on Jupiter to help bring out the Great Red Spot.
