SVBONY SV227 5nm Narrowband Filters

SVBONY SV227 filters are 5nm narrowband filters that isolate the H-alpha, OIII and SII emission lines of nebulae while blocking most light pollution and moonlight. Each line comes as a 2" mounted filter, and an SHO set groups all three in 1.25" for smaller sensors and filter wheels.

They are aimed at mono camera imagers building Hubble palette images of emission nebulae from suburban or city skies.
