These images are of the Cone Nebula area. Of course, you can also see the Fox Fur Nebula near NGC2264 (also called the Christmas Tree Cluster), B39 (the darkest nebula near the bottom), and NGC2259 (the star cluster on the lower right). It's a busy area in the Winter Milky Way. The bright star to the left that seems to be in the middle of everything is S Monocerotis, a type O7V star 4x wider than our sun and hundreds of times brighter. See info about S Mon here.
The total time for this image is 9 hours of h-alpha with DSW's FSQ.
