1.25 inch O-III Filter greatly enhances contrast during visual observation of gaseous and planetary nebulae in all sky condition; 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; allowing 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
Not only useful at light-polluted sites; the contrast is also increased at dark sky sites; can be used with all 1.25 inch eyepieces; filter made from high-grade glass with dichroic interference and antireflection coatings
Each Astromania 1.25inch O-III Filter is individually inspected and proudly inscribed with the percentage of light transmittance of the two O-III emission lines
