Optolong L-Extreme 7nm Dual Narrowband Filter (H-Alpha and O-III) (2") Size Name:2" aplus-standard ol:last-child {margin-bottom: 0The Optolong L eXtreme is a 7nm dual bandpass filter which can be used with one shot color cameras like DSLRs and CCD CMOS astrophotography cameras. It is also more suited for fast systems. The convenience and cost effectiveness of this filter allows amateurs to image emission nebulae even in bright, light polluted or moonlit skies. The L eXtreme isolates the H Alpha and Oxygen III nebula emission lines so that the contrast and signal to noise ratio
