The Helix Nebula! It's often colloquially called the Eye of God. I imaged this from my Bortle 5/6 back yard on 11/13. The Helix Nebula is a planetary nebula located in the constellation Aquarius. Planetary nebulae don't actually have anything to do with planets, but consist of a shell of ionized gas which has been ejected from a red giant star, late in its life.
This target sits low in the southern sky for me, making imaging it a challenge. Looking through so much atmosphere low in the sky means you need to wait for very favorable sky conditions to get a sharp image.
