2 inch O-III Filter greatly enhances contrast during visual observation of gaseous and planetary nebulae in all sky conditions; astrophotographic 2inch filter allows high-contrast imaging even in areas with strong light pollution
Especially useful for large aperture telescopes through which the light of the Moon can be extremely overwhelming; allow just for the double Ionized Oxygen lines between 496nm to 501nm to pass through at 95 percent
Completely blocks virtually all other visible wavelengths of light so views of nebulas are optimized; increases contrast through selective filtration-Anti-reflection coated to prevent glaring and ghosting
Double magnification: The 2x Barlow Lens simply increases the magnification of the eyepiece without significantly reducing optical quality; you can still use eyepieces with longer focal lengths for better pupil dilation and the image
4 Element Fully Multi-Coated: Premium fully variegated Telescope Barlow lenses in a four lens design are used for high-end quality planetary photos to ensure excellent correction and pin-sharp; high-contrast images without chromatic aberration
