2Inch Oxygen III (O-III) are great for viewing diffuse and planetary nebulae. 

The views of the Veil, Ring, Dumbbell, Crescent and Orion nebulae are dramatically improved.

It can crank up the contrast between them and the sky to reveal more of their wondrous detail.

It does so by transmitting close to 90% of the light corresponding to the two oxygen-III spectral lines at 496nm and 501nm while completely blocking virtually all other wavelengths.
