Description

Now that the clouds, snow, cold, and wind are back, the scopes are back in the garage. But thanks to my remote site at Deep Sky West-Chile, I've still got some data to process. This is some "bonus data" I got from their other scope (a VERY nice one) at El Sauce, and it's an object I can never image because it's always behind my neighbors trees and in the LP part of the sky due to the city lights.
M 17, also known as the Omega Nebula, is an interstellar cloud of dust and gas which is a nursery to young hot stars with a diameter of around 15 light-years and a mass of around 800 solar masses. M 17 lies about 5,000 light-years from Earth, which is about three times further than the Orion Nebula, in the Sagittarius arm of the Milky Way.
Anyway, hope ya like it!
