Notes

M8, The Lagoon Nebula in Sagittarius, shows exquisite detail when imaged through narrowband filters. This "false color" image was created using a tricolor technique by assigning SII to the red channel, H-alpha to the Green channel, and OIII to the blue channel. A top luminance layer taken from the SII data was used to complete the image.
