Description
This filter is a narrow band transmission filter with very high (99.9%) blocking of Mercury and Sodium emission pollution bands, and very high transmission of critical Hydrogen Beta and Ionized Oxygen. It is most useful in areas of extreme light pollution like cities and busy streets. The filter is particularly well suited for observing all plantary and emission nebulas. It is not generally recommended for photography.
