      Description

      I've wanted to take this picture for a couple of years, but whenever I could get to my dark sky site, it was cloudy. The stars finally aligned (literally) and I was able to get a good amount of RGB data from my dark sky site this winter.

      During my research for taking this photo, I noticed that some images had small amount of faint Hydrogen Alpha immediately around M45, so I figured I'd pile on some HA data for my wide field image and see if any more hydrogen would present itself...I was pleasantly surprised to find some wispy streams of hydrogen that I'd never seen before, right outside of the star cluster.

      The RGB data was taken from my dark sky site in Bone Cave, TN. The narrowband data was taken from my backyard in Nashville, TN.
