Astro-Tech #8 Light yellow 1.25" color filter

Recommended applications for this filter:
Moon - Improves contrast and reduces irradiation between lunar features of varying brilliance in scopes under 5", especially when combined with a polarizer or neutral density filter. Venus - Occasionally helpful in revealing low-contrast banding in the thick Venusian cloud cover. Mars - Darkens blue and green maria, oases, and canal markings while it lightens the orange-hued desert regions. Also sharpens the boundaries of yellow dust clouds. Jupiter - Somewhat useful for darkening atmospheric currents containing low-hue blue tones and enhancing detail in small orange-red zonal features in the belts. Saturn - Somewhat useful for darkening atmospheric currents containing low-hue blue tones. Neptune and Uranus - Somewhat useful for enhancing very subtle dusky features in scopes 10" and larger. Comets - Brings out highlights in yellowish comet dust tails and enhances comet heads.
