Description

HaOIIIRGB composition. The nebula mainly comes from the Ha and OIII narrow-band images, but contains small contributions from the RGB broad-band images. The stars only come from RGB. Images stacked with 2x drizzle, to take advantage of good seeing (1.0 to 1.1 arcsec for OIII), and then 50% cropped. The uploaded version is further 75% down-sampled.
