Insight Observatory is excited to announce its first deep-sky image set acquired by ATEO-3 that is now available on its Starbase image set repository. M17, the Omega Nebula in the constellation Sagittarius, was the first target imaged from the Insight Observatory affiliate remote telescope. ATEO-3 is a 12.5" f/9 (2860mm focal length) Quasar Optics Ritchey-Chretien owned and operated by Franck Jobard. This telescope is located at an elevation of over 5990 ft at Deep Sky Chile, a remote telescope hosted in the dark skies of the Rio Hurtado Valley in Chile.
The Omega Nebula, also known as the Swan Nebula, Checkmark Nebula, and the Horseshoe Nebula (cataloged as Messier 17 or M17 or NGC 6618), is an H II region in the constellation Sagittarius. It was discovered by Philippe Loys de Chéseaux in 1745. Charles Messier cataloged it in 1764. It is located in the rich starfields of the Sagittarius area of the Milky Way.
The Omega Nebula is between 5,000 and 6,000 light-years from Earth, and it spans some 15 light-years in diameter. The cloud of interstellar matter of which this nebula is a part is roughly 40 light-years in diameter and has a mass of 30,000 solar masses. The total mass of the Omega Nebula is an estimated 800 solar masses.
M17 is considered one of the brightest and most massive star-forming regions of our galaxy. Its local geometry is similar to the Orion Nebula except that it is viewed edge-on rather than face-on.
The open cluster NGC 6618 lies embedded in the nebulosity and causes the gases of the nebula to shine due to radiation from these hot, young stars. It is also one of the youngest clusters known, with an age of just 1 million years. The Swan portion of M17, the Omega Nebula in the Sagittarius nebulosity, is said to resemble a barber's pole.
