For observation of diffuse emission and planetary nebulae the Meade Oxygen-III (O-III) nebular filter is the clear choice. It provides an extraordinary level of nebular filtration. In fact with one of these filters you can often see more of a nebula in a light-polluted city environment than you can in a dark-sky setting without the filter.

The O-III filter threads into the barrels of all Meade 1.25-inch eyepieces and those of most other 1.25-inch brands. Clear aperture is 26mm. Improves detailThe filter extracts more than 80 percent of light emanating from the two oxygen-III spectral lines at 496 and 501nm. Objects such as the Omega (Swan) Nebula (M17) in Sagitarius the Orion Nebula (M42) in Orion the Helix Nebula (NGC 7293) in Aquarius and the Eagle Nebula (M16) in Serpens are revealed in dramatically increased detail. Meade 60-layer interference coating technology isolates the desirable O-III lines while nearly eliminating other spectral lines. Complements other filtersAs with Meade narrowband filters the O-III filter complements other Meade nebular filters. The effectiveness of each filter type is dependent on the light-emitting characteristics of the particular nebula being observed. However under the right conditions the O-III filter will dramatically improve your nebula-viewing experience. An astronomical laser pointer will help you share the sights with friends.
