7 hours on the Horsehead nebula from bortle 7/8. I had no moon but the gradients still killed me. Luckily I fixed them using MSGR from data supplied by @gray light . 
Definitely my best version so far but I would like to drive a ways up north and do this again from a much darker site. I can definitely do a lot better.

Bottom left, is that a satellite trail?
Otherwise, really cool image. When I saw it I said "Whoa!" Audibly

Carbonstars are so sharp

Beautiful colors

I think that's a diffraction spike from Alnitak

No, it's a star spike from Alnitak
It's jealous that I didn't place it front row in the frame so it had to find another way to sneak in.
That light "spray" on the left is also from it 
I could care less about it since Hubble has artifacts like that all the time.

Indeed.
