Premium Image Quality: Premium telescope filter for reducing the brightness of the moon and improving contrast and surface detail; reduces glare and improves definition; this can be useful when viewing the sky in areas where there is light pollution
SHARP IMAGES: A CCD camera is not only sensitive to visible light but to other wavelengths; planets are out of focus in the IR region; the Astromania filters only lets through the visible light; meaning sharp planetary images
Exquisite Detailed Design: This filter is mounted in a nicely anodized housing and comes with a filter case to better protect the filter; easy to carry around and can be used directly to explore the mysteries of nebulae anytime or anywhere
#21 Orange - The orange filter blocks blue and green wavelengths; it sharpens boundaries between orange and greenish areas; #12 Yellow - The yellow filter improves contrast on Moon craters; on Mars; channels and polar caps become more apparent
#25 Red - The red filter blocks blue and green light nearly in total; for instance; between bluish toned structures and the brighter details on Jupiter's and Saturne's clouded surface; however; this filter is mainly used to observe Martian polar caps
