SVBONY SV220 1.25 inches Telescope Filter Bundle with 1.25 inches UHC Filter and 1.25 inches UV IR Cut Block Filter

SVBONY dual narrowband H-Alpha/O-III 7nm narrowband filters are specially designed for astrophotography in light-polluted environments, allowing imaging under bright artificial light pollution and moonlight conditions to capture color images without using multiple filter combinations. Images are most useful with single-use color cameras; can be used for imaging emission nebulae, planetary nebulae, and supernova remnants; high transmittance and sharp cutoff can greatly enhance contrast, showing the most detailed information about deep sky objects; designed to drastically cut off sodium. UHC filters or light pollution reduction filters are designed to selectively reduce the transmission of certain wavelengths of light;especially those produced by artificial light. The UV-IR-Cut filter uses the very latest coating technology to deliver the high filtration quality and lifetime durability.

• 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
• 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
• UHC filters or light pollution reduction filters are designed to selectively reduce the transmission of certain wavelengths of light;especially those produced by artificial light
• This UV/IR Cut off filter blocks undesirable ultraviolet and infrared rays that may interfere with obtaining the high contrast and quality images possible with a digital sensor
• Combine with any standard 1.25” filter threads for 1.25" eyepieces and other accessories to deliver the sharpest images possible;reducing ghost images caused by IR radiation
