Image Details:

The Horn of Monoceros: 102 hours of exposure over 29 nights.

It took 4 months to get 29 clear nights, but there is so much nebulosity in this region that I just couldn’t stop piling on data to see what would be revealed.

I hope you enjoy this image as much as I enjoyed creating it!
