SVBONY SV220 Dual-Band Nebula Filter with SV503 70mm Refractor Telescope with Built-in Field Flattener

The SV220 dual-band filter is designed for astrophotography of emission nebulae, planetary nebulae and supernova remnants. The high transmission and sharp cut-off greatly enhances the contrast of image and brings out the most detailed information of those deep-sky objects.SV503 70mm telescope is ideal for observing galaxies, nebulae and star clusters, delivering crisp and bright images. It with built-in field flattener and Extra-Low Dispersion Glass, which can virtually eliminate the field curvature and chromatic aberration,providing true colors.

• 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
• 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
• Outstanding flat-field correction; built-in field flattener of SVBONY SV503 telescope eliminates field curvature; offering a flat; wide view; Observers can explore the universe freely; unhindered by edge blur or distortion
• F/6.78 and a generous 70mm aperture; SVBONY SV503 telescope delivers bright; sharp images of distant galaxies; nebulae; and star clusters; Its flat-field refractor design minimizes chromatic aberration; ensuring true-to-life colors
