- The O-III narrowband filter is specially designed for the observation of gas and planetary nebulae.
- 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 O-III narrow band-pass filter isolates just the two doubly ionized oxygen lines (496 and 501nm) emitted by diffuse, planetary and extremely faint nebulae.
- O-III filters work ideally with larger aperture telescopes in the 200mm and larger range.
- With larger aperture telescopes, observers will have a better opportunity to identify nebulae objects in the deep sky.
- It can produce near-photographic views of the Veil, Ring, Dumbbell, Orion, plus many other nebulae under dark skies.
- Supplied with storage case.
