The dark yellow filter Nr.15 1.25" from Explore Scientific is perfect for enhancing contrast during your observations of the Moon and Mars. On Jupiter, it accentuates the contrast differences between the cloud bands, revealing fascinating new details with each observation. This filter is recommended for telescopes with an aperture of at least 5", and with an 8" telescope or larger, it can even allow for identifying objects on Saturn under good viewing conditions. By reducing overexposure, it improves image clarity and enhances the overall contrast, providing you with an optimal viewing experience.
