Sagittarius Star Cloud

And its Prismatic Landscape

sagittarius star cloud astronomy singapore astrophotography

A stellar landscape of truly prismatic colours, this region of the sky is indeed a sight to behold. Many dusty tributaries also crisscross throughout the region, with a large dark lane cutting across the image in an inverted v-shape. The Sagittarius Star Cloud, or M24, is the star cloud at the top left of the image and extends beyond the field of view. At the centre of the image, we see the blue reflection nebula NGC 6589-90, as well as the emission nebula IC 1284. 

Very interestingly, there is a distinct difference in colouration of the star field in the top left section, which are generally greenish-blue, compared to those below, which tend to be golden, possibly indicating a difference in age.
