Northern Sky Narrowband Survey

The Northern Sky Narrowband Survey maps the entire northern hemisphere down to a declination of -16° in the light of the emission lines H-alpha (656.3 nm), [OIII] (500.7 nm) and [SII] (671.7 nm and 673.0 nm) as well as in continuum light. The usable angular resolution (FWHM of a point source) is about 10 arcseconds.
