The Cone Nebula is a famous nebula in the Orion Arm surrounding the NGC 2264 star cluster. The 'cone' is a triangular dark nebula near the right border of this image. The bright star at the left of this picture is 15 Monocerotis (or 'S Monocerotis') - it is a quadruple star system consisting of four brilliant blue-white stars, and it is partly responsible for causing the nebula to glow. Near the top left of the image is the Fox fur nebula. This image was taken over three nights beginning on February 9, 2012. It totals 9.5 hours of exposure, including h-alpha, RGB and luminance.
