The Scorpio 2" 3nm SHO Narrowband Filter Set gives monochrome astrophotographers the three core narrowband channels needed for classic SHO imaging: SII, H-alpha and OIII.

With a narrow 3nm bandpass, these filters are designed to isolate key nebula emission lines while reducing unwanted background light, making them a practical option for imaging emission nebulae from light-polluted skies or under less-than-ideal conditions.

The Scorpio filters offer a very attractive price point compared to many established narrowband filter brands, making them an interesting option for imagers wanting to build or upgrade a mono narrowband setup without stepping into the highest price tier.
