IC1274-5 Gum75 & NGC6559 Nebula with IC4685 Dark Nebula and M8 Lagoon Nebula in Sagittarius - 10/7/2015 (Processed stack)

Imaged at Perth Observatory site.

I'd first discovered this magnificent extended field beyond M8 Lagoon Nebula (bottom right) nearly a year before and was determined to gather a longer series of images this winter. This has turned out quite well but more light would have brought the noise level down a bit more.
