Product Description

The OIII narrowband filter in 1.25 inch isolates just the two doubly-ionized oxygen lines (496 and 501nm lines) emitted by planetary and emission nebulae, while blocking the rest of the unwanted spectrum of light. The result is extreme contrast between the 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.

Premium Coatings
Each filter has an ultra hard, vacuum-deposited coating carefully designed to block all of the visual spectrum ranging from 400 to 700nm This eliminates the un-natural colored halos surrounding bright stars common with O III filters of less sophisticated coating technology.

Fits any eyepiece or accessory with the standard 1.25 inch filter thread
