SkyWatcher O-III 2 Inch Narrowband Filter: The O-III Filter is specially designed for the observation of gas and planetary nebulae. The filter offers an easy and low cost way to identify nebulae objects in the deep sky. It distinguishes different contrasts of the wavelengths of light that pass through, giving ideal conditions for the observation of faint super nova remnants and planetary remnants.
The Skywatcher O-III filter can produce near-photographic views of the Veil, Ring, Dumbbell, Orion, plus many other nebulae under dark skies. The filter works ideally with larger aperture telescopes in the 200mm and larger range.
