Optolong L-eXtreme Dual-band Light Pollution Filter - 1.25"

Optolong Dual-band light pollution filter - 1.25-inch size. The L-eXtreme filter is dual-band that passes H-alpha and O-iii emission lines. It isolates these two nebula emission lines so that the contrast and signal-to-noise ratio between nebulae were maximized. These two elements (Hydrogen and Oxygen) factor greatly in the scientific exploration of life.
