Antlia 4.5nm EDGE Narrowband Filters

Antlia 4.5nm EDGE narrowband filters are H-alpha, OIII and SII filters with a 4.5nm bandpass, a middle ground between the tighter Antlia 3nm Pro filters and the wider 7nm Prime filters. They block most light pollution and moonlight while collecting signal faster than the narrowest options.

Used with a monochrome astronomy camera, the three filters cover a full SHO (Hubble palette) sequence for emission nebulae and supernova remnants.
