         Object NGC6334 - Cat's Paw Nebula
         Comment The Cat's Paw Nebula (NGC6334) as it's aptly named, is located in the constellation Scorpius. It is an emission nebula with a profusion of ionized hydrogen atoms that produce a vibrant red colour. The nebula is located along Milky Way galactic plane and as such is obscured by dust particles. These dust particles reduce the emission of blue and green wavelength light from the surrounding region (extinction factor). This phenomenon is known as "interstellar reddening" and is the reason why many of the young stars around and within the nebula do not exhibit blue light. The Cat's Paw Nebula is approximately 5,500 light-years distant.

This image is a LRGB composite and was taken from two instruments - Luminance:12.5" RCOS; Chrominance (RGB):Takahashi FSQ-106ED. The goal of this image was to test data up/down scaling possibilities from different focal length instruments.
