Eagle Nebula with its star-forming and well-known region of heated gas and dust that the Hubble Telescope made known as the Pillars of Creation.
The photo was taken over a week with one hour per night as M16 is around 10 degrees latitude from my balcony.
I had to fight against a lot of light pollution so I am happy with the result.
