This is my version of the Trifid Nebula in narrow band filters. The reflection nebula part is not so spectacular in OIII as seen through broad band filters. However, the emission nebula is strong in all SHO filters, what brings great opportunity for creative visions of this beautiful object. Stars were taken from the broad band image posted before.
