Baader Planetarium 2" Oxygen III Nebula Filter FOIII-2 Reviews

Baader Planetarium 2" Oxygen III Nebula Filter FOIII-2

The Baader Planetarium Oxygen III Filter delivers the absolute highest contrast views of many diffuse and planetary nebula. For many objects, the Baader Planetarium O-III reveals a level of intricate detail that rivals the best deep sky photographs. Our favorite filter for the majority of nebula, especially The Veil, Lagoon (M8), Swan (M17), Ring (M57) and Dumbell (M29). With a large scope, you can even view the famous 'Pillars of Creation' in M16 (Eagle).


The Baader Planetarium Oxygen III Filter perfectly isolates the two doubly ionized oxygen lines (496 and 501nm), through a very sharp and narrow bandpass (8.2 nm wide!, the narrowest of any O-III filter). Unlike other O-III filters, the Baader Planetarium O-III completely blocks longer and shorter wavelengths (ever wonder why some O-III filters appear RED?, instead of the correct 500 nm Teal color). The result is the highest contrast achievable in an O-III filter.

The Baader Planetarium Oxygen III benefits from the precision fineoptically polished flat substrate, and advanced DWDM plasma assisted coatings. As a result, the Baader O-III will not degrade image sharpness or impart double images. To prevent deterioration from cleaning or exposure to moisture, some other filters even resort to sandwiching their delicate coatings between two layers of filter glass, resulting in potential blurred or double images. Contrary to myth, nebula filters are often useful at high magnifications, where image quality counts. Baader O-III filters can take high magnifications, and stars retain their pinpoint sharpness, even if the filter is used far ahead of the image plane (ie, for imaging use, or ahead of a star diagonal or binoviewer). Combine with our UV/IR filter for the ultimate in O-III deep sky imaging.

Celestron 93624 Narrowband Oxygen III 2 Filter Reviews

Celestron 93624 Narrowband Oxygen III 2 Filter

• For viewing many common nebulas
• Reduces glare and light scattering
• Increases contrast through selective filtration
• Made of high quality, solid plane parallel glass with excellent homogeneity
• Anti-reflection coated to prevent glaring and ghosting

Celestron Oxygen-III Narrowband Filter - 2in 93624The Celestron 93624 Narrowband Oxygen III 2-inch filter is a remarkable advance for the serious visual observer of emission nebulae. One of the biggest advantages of narrowband filters is that by passing only the light emitted by nebulae, light from artificial sources like street lights is blocked. This allows you to take detailed exposures of nebulas from a suburban location that can rival shots from much darker sites. The Celestron 93624 is made of high quality, solid plane parallel glass.
