Special Features

  • The Oxygen III 1.25" filter isolates just the two doubly-ionized oxygen lines emitted by planetary and emission nebulae, while blocking rest of the spectrum of light (Celestron 93623).
  • The neutral density moon filter provides 13% light transmission for reduced brightness and glare of the moon, Venus and bright double stars (Celestron ND filter).
  • The Oxygen III filter is made in China and has package dimensions of 3.0 x 1.0 x 3.0 inches (Celestron 93623).
  • The neutral density filter threads onto any 1.25" Celestron eyepiece for easy attachment (Celestron ND filter).
  • The bundle combines specialized filtration for enhanced views of nebulae and lunar/planetary observations.

Description

Celestron 93623 Narrowband Oxygen III 1.25 Filter
The 1-1/4" OIII narrowband filter isolates just the two doubly-ionized oxygen lines (496 and 501nm lines) emitted by planetary and emission nebulae, while blocking the rest of the overall spectrum of light. The result is extreme contrast between the black sky background and the faint photons of OIII light needed for detailed views of the Veil, Ring, Dumbbell, Crescent and Orion nebulae, among other objects. Each filter has an ultra hard, vacuum-deposited coating carefully designed to block all of the visual spectrum ranging from 400 to 700 nm This eliminates the un-natural colored halos surrounding bright stars common with O III filters of less sophisticated coating technology.
