From what I can find online, this is the largest image of the lagoon nebula ever captured by an astrophotographer. This is one of the brightest and most well-known star-forming regions in the milky way. It sits directly towards the center of our galaxy in the constellation Sagittarius. Young hot stars emit tons of radiation, making the gas around them glow a bright red color.
This image was captured as a 3-panel Ha-RGB mosaic from SRO using the 16" RCOS telescope. At an image size of 150MPX and 0.2"/pixel resolution, this is the largest image that an amateur has ever captured of the region.
