The 1.25" yellow-green filter No. 11 from Explore Scientific significantly enhances contrast when observing celestial objects, notably the moon, Mars, and Jupiter. It accentuates the differences between Jupiter's cloud bands and reveals more details on the lunar and Martian surface. With a telescope of at least 8" in diameter, this filter even allows for the observation of objects on Saturn, under optimal viewing conditions. By slightly reducing brightness, it prevents overexposure and enables more detailed observation.
