Main highlights

Reduce light pollution; SV220 telescope filter can greatly reduce the interference from natural light sources such as moonlight or artificial light pollution such as street lighting

Improving contrast; an increase in contrast can be perceived as an increase in brightness; the filter makes the contrast of the nebula and sky background increase; not the nebula brighter

Astrophotographic;the filter enhances contrast during visual observation of gaseous and planetary nebulae in all sky conditions; the filter allows high-contrast imaging even in areas with strong light pollution

Main highlights

【Variable Polarizing Filters】 Two rotating variable polarizing filters change light transmission from 40% to 1%. They reduce reflection and glare, darken the sky background, and boost visual contrasts to make planets and stars stand out. No chromatic aberration.

【Combine to Get a Variable ND Filter】Stacking two polarizing filters together will give you a variable ND2-2000 ND filter, which can be used freely on the telescope without affecting the focal length at all, helping you to capture more brilliant star rivers. Note: The thinner polarizing filter needs to be mounted underneath the ringed polarizing filter.

【5 Planetary Color Filters】 5 planetary filters in red, orange, yellow, green, and blue reveal details, emphasize features, and sharpen the contrast of Mercury, Mars, Venus, Jupiter, Saturn, Moon, and other celestial objects
