Image Details:

The Heart, Soul, and Bear Claw Nebulas. Taken over the course of 7 nights from Nashville, TN. A total of 33 hours exposure.

One of my favorite things about astrophotography is "surprises" that show up in images. I lined up the Heart and Soul Nebulas (aptly named) in the frame, and started my exposures. All was going as planned, until about 10 hours into taking this image, when a pale blue smudge started showing up on the bottom/right of the frame. I initially thought it was a blemish/internal reflection that was causing unwanted errors in the image, but after a little research I found that it was another nebula...the Bear Claw Nebula. It's the little things in life, you know? The ones that are hundreds of light years wide! 🙂

I hope you enjoy this image as much as I enjoyed taking it.
