The 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.
