This star photo was taken by John Reichelt using a Canon 550D with a 765 mm focal length telescope (f/6.4) and an exposure time of 150 seconds at ISO 6400. The photos were taken at Mudgeeraba in October 2015. A series of 3 different shots were combined in a panorama program.
The Trifid Nebula (scientific name: Messier 20) is a combination of the 3 main types of cloud objects seen in space; namely emission nebulae (the red areas of glowing hydrogen), reflection nebulae (the blue areas of reflected light from new baby stars bouncing off gas clouds) and dark nebulae (cold gas and dust blocking all light).
This object is 10 light years in diameter and about 5200 light years away in the constellation Sagittarius.
The Lagoon Nebula (scientific name: Messier 8) is a giant interstellar gas cloud in the constellation Sagittarius. It is over 50 light years in diameter and about 5000 light years away. The brightest area is where new baby stars are forming and just below that area there is a collection of very young stars formed from the same cloud. Dark globules of dust and cold gas are present as well.
