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 differences between Jupiter's cloud bands and reveals more details about the lunar and Martian surfaces. 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.
