The Cone Nebula, Fox Fur Nebula, and Christmas Tree Cluster. Shot over two nights, most of the time devoted to Ha plus a few hours of RGB binned 2x2. Ha was used as luminance, and blended into the color data with PixInsight's NBRGB script with a healthy boost.

The blue reflection nebula got kinda washed out by the LRGB combination despite my best efforts to fit the luminance of L and RGB. A challenge for next time..
