Product Specifications

Meade Oxygen-III (O-III) nebular filters provide an extraordinary level of nebular filtration on diffuse and planetary nebulae. Observations of these nebulae in a city environment with the O-III filter often yield more image contrast than observations of the same objects in a dark-sky setting without the filter. The O-III filter extracts more than 80% of the light emanating from the two oxygen-III spectral lines at 496 and 501nm. Meade 60-layer interference coating technology isolates the desirable O-III lines, while attenuating other spectral lines virtually to zero. As with Meade Narrowband Filters, the O-III Filters are complements to other Meade nebular filters; the effectiveness of each filter type is highly dependent on the physical characteristics of the particular nebula being observed. #911X threads onto the rear cells of Meade LX-series mirror-lens telescopes and onto Meade ED Apochromatic Refractors, using the Universal Thread Adapter. Also threads to other brands of SCT's as well. Clear aperture is 36mm. #911X Oxygen-III Nebular features Rear Cell Thread.
