Summary
[edit]DescriptionCrescent Nebula - Flickr - astrophotography andy.jpg |
It formed by the fast stellar wind from the Wolf-Rayet star WR 136 (Bright star in the middle) colliding with and energizing the slower moving wind ejected by the star when it became a red giant. Had to overcome a bunch of issues last night. Think I ended up imaging our neighbors pine tree at one point and had some autoguiding issues. I expected higher quality... anyway, here is Crescent Nebula after 1 hour and 35 minutes.
