The Rosette Nebula, January 17, 2020
Friday evening was the first clear one in 10 nights, for a bit, as I was only able to capture 27 minutes worth of data before more clouds returned. I would like to have at least 2 hours, or more, of exposure on a target like this one. However, it was long enough to capture this beautiful rose in the heavenly sky.

The Rosette Nebula, also known as Caldwell 49, is a lovely nebula about 5,000 light-years away. The brilliant colors are produced from the radiation from the young stars illuminating a surrounding dust cloud. There are numerous new-born stars inside the optical nebula. In the sky, it is located on the upper left side (East) of the famous constellation of Orion the Hunter in the constellation of Monoceros (Unicorn).
