NGC6334, the Cat's paw Nebula in lower right, is a reddish diffused nebula with a size of about 20 arc minutes. It consists of several segments of three round red lights and a dimmed vast region, only appears clearly on long-exposed photos. The unique-shape has given a nickname of "Cat's paw nebula", and the nebula has another nickname of "The Telescope Goldfish Nebula" in Japan. It looks like a kind of goldfish with its eyes sticked out. NGC6357 in upper left has an apparent size of about 50 arc minutes, and is often called "The Cluster Amaryllis Nebula" at Japan (in Japanese "Higan-bana" Nebula), because the shape of it looks like a huge reddish flower.
