The Lagoon Nebula is a giant interstellar cloud in the constellation Sagittarius. The distance is estimated to be between 4,000-6,000 light years from the Earth. In the sky of Earth, it spans 90' by 40', translates to an actual dimension of 110 by 50 light years.
I capture it on July 17. 2011., through a WO Megrez 80/480 triplet fluorite APO, TeleVue 0,8x field flattener, SBIG ST8300C CCD, IR/UV Baader, CGEM mount, QHY5 guider. Exposure was 10x360 second.
