In the center of the image, the stars cluster to form a bright and dense green candy floss-colored haze, that is the Large Magellanic Cloud. Scattered across the middle of the image are about 50 small yellow crosses, some of them are so close to one another that they almost overlap. SNR J0624-6948 (orange, higher in the image) and SNR J0614-7251 (blue, lower in the image) are seen in the lower left quarter of the image.
