NGC 2244 The Rosette Nebula

NGC 2244 – The Rosette Nebula

With only a couple days clear all winter in 2023-24, I finally got a window of taking images and captured NGC 2244 which is the Rosette Nebula.  NGC 2244 is actually the inner star cluster found within, showing hot blue new stars springing to life.
