Astromania 2 O-III Filter - Produces Near-Photographic Views of The Veil, Ring, Dumbbell and Orion Nebula, Among Many Other Objects
The Astromania 2 O-III Filter is comparable to the Astromania UHC filter in its function. The difference is that this filter only allows the light of doubly ionized oxygen through. This means that there is an enormous increase in contrast with diffuse, planetary and extremely dim nebulae. This is a special narrowband filter which allows an even smaller range of wavelengths than the Astromania UHC filter. Even so, there are innumerable astronomical objects which can be first observed in detail with this filter or cannot be seen at all without it. A prime example is the Veil neb
