The nebula NGC 3503 in Carina is a stellar nursery that glows brightly at the center of this image, surrounded by ghostly tendrils of gas and dust. At bottom right is the open cluster NGC 3532. The image comprises just over 17 hours of SHORGB data taken with a 4-inch f/5.5 scope from Buenos Aires, and also the town of Pardo under Bortle 2 skies.
