saxon Colour Planetary Filter No.21 – Orange (1.25")

Boost contrast and surface detail on your favourite planetary targets with the saxon Colour Planetary Filter No.21 – Orange (1.25"). Allowing 46% light transmission, this filter is highly effective in enhancing features on Jupiter, such as the Great Red Spot and equatorial belts, while also delivering excellent results when observing Mars.

By filtering green and blue wavelengths, this orange filter improves atmospheric contrast and surface visibility, making it one of the best options for planetary viewing through telescopes with a 1.25" eyepiece. It also enhances clarity during imaging sessions, particularly in planetary astrophotography.
