M17 - The Swan Nebula

M17 – The Swan Nebula

Also known as the Omega Nebula

Messier 17, or the Swan Nebula is located in the constellation Sagittarius. This deep-sky astrophotography target is an H II region where star formation has recently taken place.  Also known as the Omega Nebula, this object rises high enough from my latitude to start imaging in early April if you stay up late enough!  It’s always exciting to see M17 for the first time in the year, as it marks the beginning of “milky-way” season for stargazers.
