There are several objects in this frame: the largest NGC 1763, in the centre, NGC1769 the second largest, and NGC1773, more towards the 2 o'clock position. They are the milky blue-white areas of an Emission Nebula in Dorado. From my location, they are circumpolar (the object never sets). These complex nebulae reside within the Magellanic Clouds and are extremely important to studying the star formation process in low metallicity environments.
Whenever I process an object with red, green, or blue filters, I am amazed by the number of blue stars in the magellanic clouds.
This image was created using five filters: Red, Green, Blue, Luminance, and Ha. I love the more traditional colour rendition of astronomical objects. With the addition of Ha data, I was able to extend the reds just a little further, hopefully without becoming too overwhelming or distracting.
