Messier 16: a wide view of the “Eagle Nebula” – 28 May 2017
For sure, Messier 16 in one of the most famous and beautiful treasures out there. It is a vaste region of star formation, including a nice open cluster (NGC 6611) and a wide nebula (IC 4703).
This cosmic nursery is placed at about 7000 light years from us and it was discovered by Philippe Loys de Chéseaux in 1745-6. A binocular can easily show this complex, in the middle of the Milky Way, in the Serpens Cauda constellation. Wide field scopes, under dark skies, can make the vision mind-blowing, with plenty of details and countless stars.
The image above comes from the sigma-clipping combination of six, 120-seconds exposures, unfiltered, remotely taken with the 16″-f/3.75 Tenagra III (“Pearl”) robotic unit part of Tenagra Observatories in Arizona. The imaging camera is based on the KAF-16801 CCD. The resulting image scale is 2.4″/pixel.
